Relatively new to React, and am wanting to recreate the design below
enter image description here
I have the base formatting down, but as you will notice, there are lines separating the logo blocks, from the login and signup blocks, with the signup and login buttons pushed to the bottom.
Below is my current code
CSS:
width: 100vw;
height: 100vh;
}
body {
margin: 0;
padding: 0;
}
.Sidebar {
height: 100%;
width: 20%;
background-color: white;
border-right: 1px solid #F0F4FB;
padding-left: 15px;
box-sizing: border-box;
}
.SidebarList {
height: auto;
width: 100%;
padding-left: 15px;
font-size: 18px;
border: 2px #FD954E;
box-sizing: border-box
}
.SidebarList .row {
width: 100%;
height: 50px;
background-color: white;
list-style-type: none;
margin: 0%;
padding-bottom: 15px;
display: flex;
color: #A7ACB6;
justify-content: center;
align-items: center;
font-family: Arial, Helvetica, sans-serif;
}
.SidebarList .row:hover {
cursor: pointer;
background-color: #E7E7E7 ;
}
.SidebarList #active {
background-color: white;
color: #FD954E
}
.SidebarList .Login {
background-color: white;
color: #FD954E;
width: 279px;
height: 39px;
right: 1596px;
top: 958px;
border: 1px solid #FD954E;
box-sizing: border-box;
border-radius: 19.5px;
}
.SidebarList .SignUp {
width: 279px;
height: 39px;
right: 1596px;
top: 1011px;
background: #FD954E;
border-radius: 19.5px;
border: none;
}
.row #icon {
flex: 30%;
display: grid;
place-items: center;
transform: scale(1.2)
}
.row #title {
flex: 70%;
}
.Logo {
padding-left: 25px;
padding-top: 25px;
padding-bottom: 30px;
border-bottom: 1px solid #F0F4FB;
width: 55%;
}
Sidebar.js
import React from "react";
import "../App.css";
import { SidebarData } from './SidebarData'
import Logo from './Logo.svg'
function Sidebar() {
return (
<div className="Sidebar">
<div>
<img src = {Logo} alt='Logo’ className=‘Logo’ />
</div>
<ul className="SidebarList">
{SidebarData.map((val, key) => {
return (
<li
key={key}
className="row"
id={window.location.pathname == val.link ? "active" : ""}
onClick={() => {
window.location.pathname = val.link;
}}
>
<div id="icon">{val.icon}</div> <div id="title">{val.title}</div>
</li>
);
})}
</ul>
<div className= "SidebarList">
<button className="Login">
Login
</button>
</div>
<div className= "SidebarList">
<button className="SignUp">
Sign Up
</button>
</div>
</div>
);
}
export default Sidebar;
How should I structure my code in order to acheive my desired result? Ex: with the logo at the top with the seperator, the list of navigation elements, and then the login and signup buttons at the bottom with the seperator?
Currently, my sidebar looks as follows, with the seperator not full width between the logo and navigation elements, and the buttons extending beyond the sidebar.

It would be easier to simplify the problem with just HTML and CSS as that's much easier to troubleshoot. Part of your problem is that you are defining the width of the sidebar as a percentage of the screen width but elements within the sidebar are defined with a width in pixels. When the browser window is too small, your buttons will appear outside the full width of the sidebar. You could either code all your values as percentages or in pixels. Alternatively, you could use a mix and just set a min-width for the sidebar so that you don't end up with elements out of place.
The reason that your line break is not the full width of your sidebar is because you are defining it with the border-bottom property of the logo. Your logo is not 100% the width of the sidebar so your line break will only be the width of the logo. A better solution would be to define a div that is set to width: 100%. This way, you will have more control.
Here is a simplified solution to your sidebar problem using pixels to define the widths.
HTML:
<div class="sidebar">
<div class="header">
<div class="logo">Logo</div>
</div>
<div class="line-break" />
<div class="content">
<ul class="nav">
<li>Home</li>
<li>Blog</li>
</ul>
</div>
<div class="line-break" />
<div class="footer">
<button class="login">Login</button>
<button class="sign-up">Sign up</button>
</div>
</div>
CSS:
html, body {
height: 100%;
margin: 0;
padding: 0;
}
.sidebar {
width: 300px;
height: 100%;
border-right: 1px solid grey;
}
.line-break {
height: 1px;
width: 100%;
background-color: grey;
}
.header .logo {
height: 40px;
width: 200px;
background-color: grey;
margin: 20px;
}
ul.nav {
list-style-type: none;
padding: 20px 0 0 40px;
}
ul.nav li {
margin-bottom: 14px;
}
ul.nav li:last-child {
margin-bottom: 0;
}
.footer {
display: flex;
flex-direction: column;
align-items: center;
padding: 20px 0;
}
.footer button {
padding: 6px 0;
width: 80%;
margin-bottom: 14px;
}
.footer button:last-child {
margin-bottom: 0;
}
And here is a link to a CodePen
where you can see this in action.
I want to design a dynamic nav tabs component. when the card is clicked relevant tab is shown, with the connection arrow and border-color green.
sample code or a suggestion would be much helpful
.
You can use accordion by bootstrap. Use css flexbox to horizontally align the tabs next to each other and bind a javascript method that changes css color properties (arrow, green color) on clicking.
Here is the link - https://getbootstrap.com/docs/4.0/components/collapse/
Here is how you can do :
.js :
import React, { Component } from "react";
import { render } from "react-dom";
import "./style.css";
const App = () => {
const selectBlock = (e) => {
e.target.classList.toggle('selected');
}
return (
<div className="block" onClick={(e) => {selectBlock(e)}}>
<div>Here is the block</div>
<div className="arrow">
<FakeArrow />
</div>
</div>
);
};
const FakeArrow = () => {
return (
<div>
<span className="arrow-down-border" />
<span className="arrow-down" />
</div>
);
};
render(<App />, document.getElementById("root"));
.css :
.block {
position: relative;
width: 150px;
height: 50px;
text-align: center;
border: 2px solid black;
}
.arrow {
display: none;
}
.block.selected {
border: 2px solid #99d32c;
}
.block.selected .arrow {
display: block;
}
/* You need to fake the arrow border with another arrow behind */
.arrow-down-border {
position: absolute;
bottom: -20px;
left: 55px; /* 150px (main block) / 2 -20px (size of the triangle)*/
width: 0;
height: 0;
border-left: 20px solid transparent;
border-right: 20px solid transparent;
border-top: 20px solid #99d32c;
}
.arrow-down{
position: absolute;
bottom: -17px;
left: 58px; /* 150px (main block) / 2 -17px (size of the triangle)*/
width: 0;
height: 0;
border-left: 17px solid transparent;
border-right: 17px solid transparent;
border-top: 17px solid #ffffff;
}
Here is the repro on Stackblitz.
Of course this is just an example, you have to set a color for the arrows so my advice would be to do it with constants or props. Same thing for the position and others functionality you can add to the FakeArrow component.
Now, it would be waaaayy easier to manage it with an image if you really need a border (this is the tricky part in your requirement), or a simple arrow without border.
You can take a look at this post, it's the same question actually, i used a slightly different way to do it with css, but the result seems to be the same.
I want to center a div vertically with CSS. I don't want tables or JavaScript, but only pure CSS. I found some solutions, but all of them are missing Internet Explorer 6 support.
<body>
<div>Div to be aligned vertically</div>
</body>
How can I center a div vertically in all major browsers, including Internet Explorer 6?
Below is the best all-around solution I could build to vertically and horizontally center a fixed-width, flexible height content box. It was tested and worked for recent versions of Firefox, Opera, Chrome, and Safari.
.outer {
display: table;
position: absolute;
top: 0;
left: 0;
height: 100%;
width: 100%;
}
.middle {
display: table-cell;
vertical-align: middle;
}
.inner {
margin-left: auto;
margin-right: auto;
width: 400px;
/* Whatever width you want */
}
<div class="outer">
<div class="middle">
<div class="inner">
<h1>The Content</h1>
<p>Once upon a midnight dreary...</p>
</div>
</div>
</div>
View A Working Example With Dynamic Content
I built in some dynamic content to test the flexibility and would love to know if anyone sees any problems with it. It should work well for centered overlays also -- lightbox, pop-up, etc.
The simplest way would be the following three lines of CSS:
1) position: relative;
2) top: 50%;
3) transform: translateY(-50%);
Following is an example:
div.outer-div {
height: 170px;
width: 300px;
background-color: lightgray;
}
div.middle-div {
position: relative;
top: 50%;
-webkit-transform: translateY(-50%);
-ms-transform: translateY(-50%);
transform: translateY(-50%);
}
<div class='outer-div'>
<div class='middle-div'>
Test text
</div>
</div>
One more I can't see on the list:
.Center-Container {
position: relative;
height: 100%;
}
.Absolute-Center {
width: 50%;
height: 50%;
overflow: auto;
margin: auto;
position: absolute;
top: 0; left: 0; bottom: 0; right: 0;
border: solid black;
}
Cross-browser (including Internet Explorer 8 - Internet Explorer 10 without hacks!)
Responsive with percentages and min-/max-
Centered regardless of padding (without box-sizing!)
height must be declared (see Variable Height)
Recommended setting overflow: auto to prevent content spillover (see Overflow)
Source: Absolute Horizontal And Vertical Centering In CSS
Now the Flexbox solution is a very easy way for modern browsers, so I recommend this for you:
.container {
display: flex;
align-items: center;
justify-content: center;
height: 100%;
background: green;
}
body,
html {
height: 100%;
}
<div class="container">
<div>Div to be aligned vertically</div>
</div>
Actually, you need two div's for vertical centering. The div containing the content must have a width and height.
#container {
position: absolute;
top: 50%;
margin-top: -200px;
/* Half of #content height */
left: 0;
width: 100%;
}
#content {
width: 624px;
margin-left: auto;
margin-right: auto;
height: 395px;
border: 1px solid #000000;
}
<div id="container">
<div id="content">
<h1>Centered div</h1>
</div>
</div>
Here is the result.
Edit 2020: only use this if you need to support old browsers like Internet Explorer 8 (which you should refuse to do 😉). If not, use Flexbox.
This is the simplest method I found and I use it all the time
(jsFiddle demo here).
Thank Chris Coyier from CSS Tricks for this article.
html, body{

</article>
</div>
Support starts with Internet Explorer 8.
After a lot of research I finally found the ultimate solution. It works even for floated elements. View Source
.element {
position: relative;
top: 50%;
transform: translateY(-50%); /* or try 50% */
}
Use the CSS Flexbox align-items property to achieve this.
html, body {
height: 100%;
}
body {
display: flex;
align-items: center;
}
<div>This is centered vertically</div>
To center the div on a page, check the fiddle link.
#vh {
margin: auto;
position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
}
.box{
border-radius: 15px;
box-shadow: 0 0 8px rgba(0, 0, 0, 0.4);
padding: 25px;
width: 100px;
height: 100px;
background: white;
}
<div id="vh" class="box">Div to be aligned vertically</div>
Another option is to use flex box, check the fiddle link.
.vh {
background-color: #ddd;
height: 400px;
align-items: center;
display: flex;
}
.vh > div {
width: 100%;
text-align: center;
vertical-align: middle;
}
<div class="vh">
<div>Div to be aligned vertically</div>
</div>
Another option is to use a CSS 3 transform:
#vh {
position: absolute;
top: 50%;
left: 50%;
/*transform: translateX(-50%) translateY(-50%);*/
transform: translate(-50%, -50%);
}
.box{
border-radius: 15px;
box-shadow: 0 0 8px rgba(0, 0, 0, 0.4);
padding: 25px;
width: 100px;
height: 100px;
background: white;
}
<div id="vh" class="box">Div to be aligned vertically</div>
The easiest solution is below:
.outer-div{
width: 100%;
height: 200px;
display: flex;
border:1px solid #000;
}
.inner-div{
margin: auto;
text-align: center;
border: 1px solid red;
}
<div class="outer-div">
<div class="inner-div">
Hey there!
</div>
</div>
There are multiple ways to achieve this.
Using flex property of CSS.
Solution #1
.parent {
width: 400px;
height:200px;
background: blue;
display: flex;
align-items: center;
justify-content:center;
}
.child {
width: 75px;
height: 75px;
background: yellow;
}
<div class="parent">
<div class="child"></div>
</div>
or by using display: flex; and margin: auto;
Solution #2
.parent {
width: 400px;
height:200px;
background: blue;
display: flex;
}
.child {
width: 75px;
height: 75px;
background: yellow;
margin:auto;
}
<div class="parent">
<div class="child"></div>
</div>
show text center
Solution #3
.parent {
width: 400px;
height: 200px;
background: yellow;
display: flex;
align-items: center;
justify-content:center;
}
<div class="parent">Center</div>
Using percentage(%) height and width.
Solution #4
.parent {
position: absolute;
height:100%;
width:100%;
background: blue;
display: flex;
align-items: center;
justify-content:center;
}
.child {
width: 75px;
height: 75px;
background: yellow;
}
<div class="parent">
<div class="child"></div>
</div>
Unfortunately — but not surprisingly — the solution is more complicated than one would wish it to be. Also unfortunately, you'll need to use additional divs around the div you want vertically centered.
For standards-compliant browsers like Mozilla, Opera, Safari, etc. you need to set the outer div to be displayed as a table and the inner div to be displayed as a table-cell — which can then be vertically centered. For Internet Explorer, you need to position the inner div absolutely within the outer div and then specify the top as 50%. The following pages explain this technique well and provide some code samples too:
Vertical Centering in CSS
Vertical Centering in CSS with Unknown Height (Internet Explorer 7 compatible) (Archived article courtesy of the Wayback Machine)
There is also a technique to do the vertical centering using JavaScript. Vertical alignment of content with JavaScript & CSS demonstrates it.
If someone cares for Internet Explorer 10 (and later) only, use Flexbox:
.parent {
width: 500px;
height: 500px;
background: yellow;
display: -webkit-flex;
display: -ms-flexbox;
display: flex;
-webkit-justify-content: center;
-ms-flex-pack: center;
justify-content: center;
-webkit-align-items: center;
-ms-flex-align: center;
align-items: center;
}
.centered {
width: 100px;
height: 100px;
background: blue;
}
<div class="parent">
<div class="centered"></div>
</div>
Flexbox support: http://caniuse.com/flexbox
A modern way to center an element vertically would be to use flexbox.
You need a parent to decide the height and a child to center.
The example below will center a div to the center within your browser. What's important (in my example) is to set height: 100% to body and html and then min-height: 100% to your container.
body, html {
background: #F5F5F5;
box-sizing: border-box;
height: 100%;
margin: 0;
}
#center_container {
align-items: center;
display: flex;
min-height: 100%;
}
#center {
background: white;
margin: 0 auto;
padding: 10px;
text-align: center;
width: 200px;
}
<div id='center_container'>
<div id='center'>I am center.</div>
</div>
.center {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%); /* (x, y) => position */
-ms-transform: translate(-50%, -50%); /* IE 9 */
-webkit-transform: translate(-50%, -50%); /* Chrome, Safari, Opera */
}
.vertical {
position: absolute;
top: 50%;
//left: 0;
transform: translate(0, -50%); /* (x, y) => position */
}
.horizontal {
position: absolute;
//top: 0;
left: 50%;
transform: translate(-50%, 0); /* (x, y) => position */
}
div {
padding: 1em;
background-color: grey;
color: white;
}
<body>
<div class="vertical">Vertically left</div>
<div class="horizontal">Horizontal top</div>
<div class="center">Vertically Horizontal</div>
</body>

Centering only vertically
If you don't care about Internet Explorer 6 and 7, you can use a technique that involves two containers.
The outer container:
should have display: table;
The inner container:
should have display: table-cell;
should have vertical-align: middle;
The content box:
should have display: inline-block;
You can add any content you want to the content box without caring about its width or height!
Demo:
body {
margin: 0;
}
.outer-container {
position: absolute;
display: table;
width: 100%; /* This could be ANY width */
height: 100%; /* This could be ANY height */
background: #ccc;
}
.inner-container {
display: table-cell;
vertical-align: middle;
}
.centered-content {
display: inline-block;
background: #fff;
padding: 20px;
border: 1px solid #000;
}
<div class="outer-container">
<div class="inner-container">
<div class="centered-content">
Malcolm in the Middle
</div>
</div>
</div>

Centering horizontally and vertically
If you want to center both horizontally and vertically, you also need the following.
The inner container:
should have text-align: center;
The content box:
should re-adjust the horizontal text-alignment to for example text-align: left; or text-align: right;, unless you want text to be centered
Demo:
body {
margin: 0;
}
.outer-container {
position: absolute;
display: table;
width: 100%; /* This could be ANY width */
height: 100%; /* This could be ANY height */
background: #ccc;
}
.inner-container {
display: table-cell;
vertical-align: middle;
text-align: center;
}
.centered-content {
display: inline-block;
text-align: left;
background: #fff;
padding: 20px;
border: 1px solid #000;
}
<div class="outer-container">
<div class="inner-container">
<div class="centered-content">
Malcolm in the Middle
</div>
</div>
</div>
See also this Fiddle!
It can be done in two ways
body{
left: 50%;
top:50%;
transform: translate(-50%, -50%);
height: 100%;
width: 100%;
}
OR
Using flex
body {
height:100%
width:100%
display: flex;
justify-content: center;
align-items: center;
}
align-items:center; makes the content vertically center
justify-content: center;makes the content horizontally center
This is always where I go when I have to come back to this issue.
For those who don't want to make the jump:
Specify the parent container as position:relative or position:absolute.
Specify a fixed height on the child container.
Set position:absolute and top:50% on the child container to move the top down to the middle of the parent.
Set margin-top:-yy where yy is half the height of the child container to offset the item up.
An example of this in code:
<style type="text/css">
#myoutercontainer {position:relative}
#myinnercontainer {position:absolute; top:50%; height:10em; margin-top:-5em}
</style>
...
<div id="myoutercontainer">
<div id="myinnercontainer">
<p>Hey look! I'm vertically centered!</p>
<p>How sweet is this?!</p>
</div>
</div>
I just wrote this CSS and to know more, please go through: This article with vertical align anything with just 3 lines of CSS.
.element {
position: relative;
top: 50%;
transform: perspective(1px) translateY(-50%);
}
For newcomers, please try:
display: flex;
align-items: center;
justify-content: center;
The three lines of code using transform works practically on modern browsers and Internet Explorer:
.element{
position: relative;
top: 50%;
transform: translateY(-50%);
-moz-transform: translateY(-50%);
-webkit-transform: translateY(-50%);
-ms-transform: translateY(-50%);
}
I am adding this answer since I found some incompleteness in the previous version of this answer (and Stack Overflow won't allow me to simply comment).
'position' relative messes up the styling if the current div is in the body and has no container div. However 'fixed' seems to work, but it obviously fixes the content in the center of the viewport
Also I used this styling for centering some overlay divs and found that in Mozilla all elements inside this transformed div had lost their bottom borders. Possibly a rendering issue. But adding just the minimal padding to some of them rendered it correctly. Chrome and Internet Explorer (surprisingly) rendered the boxes without any need for padding
CSS Grid
body, html { margin: 0; }
body {
display: grid;
min-height: 100vh;
align-items: center;
}
<div>Div to be aligned vertically</div>
.center{
display: grid;
place-items: center;
}
The answer from Billbad only works with a fixed width of the .inner div.
This solution works for a dynamic width by adding the attribute text-align: center to the .outer div.
.outer {
position: absolute;
display: table;
width: 100%;
height: 100%;
text-align: center;
}
.middle {
display: table-cell;
vertical-align: middle;
}
.inner {
text-align: center;
display: inline-block;
width: auto;
}
<div class="outer">
<div class="middle">
<div class="inner">
Content
</div>
</div>
</div>
Just do it: Add the class at your div:
.modal {
margin: auto;
position: absolute;
top: 0;
right: 0;
left: 0;
bottom: 0;
height: 240px;
}
And read this article for an explanation. Note: Height is necessary.
I did it with this (change width, height, margin-top and margin-left accordingly):
.wrapper {
width: 960px;
height: 590px;
position: absolute;
top: 50%;
left: 50%;
margin-top: -295px;
margin-left: -480px;
}
<div class="wrapper"> -- Content -- </div>

display: -webkit-flex;
display: flex;
align-items: center;
justify-content: center;
I think a solid solution for all browsers without using Flexbox - "align-items: center;" is a combination of display: table and vertical-align: middle;.
CSS
.vertically-center
{
display: table;
width: 100%; /* Optional */
height: 100%; /* Optional */
}
.vertically-center > div
{
display: table-cell;
vertical-align: middle;
}
HTML
<div class="vertically-center">
<div>
<div style="border: 1px solid black;">some text</div>
</div>
</div>

Especially for parent divs with relative (unknown) height, the centering in the unknown solution works great for me. There are some really nice code examples in the article.
It was tested in Chrome, Firefox, Opera, and Internet Explorer.
/* This parent can be any width and height */
.block {
text-align: center;
}
/* The ghost, nudged to maintain perfect centering */
.block:before {
content: '';
display: inline-block;
height: 100%;
vertical-align: middle;
margin-right: -0.25em; /* Adjusts for spacing */
}
/* The element to be centered, can
also be of any width and height */
.centered {
display: inline-block;
vertical-align: middle;
width: 300px;
}
<div style="width: 400px; height: 200px;">
<div class="block" style="height: 90%; width: 100%">
<div class="centered">
<h1>Some text</h1>
<p>Any other text..."</p>
</div>
</div>
</div>
There is a trick I found out recently: You need to use top 50%, and then you do a translateY(-50%).
.outer-div {
position: relative;
height: 150px;
width: 150px;
background-color: red;
}
.centered-div {
position: absolute;
top: 50%;
-webkit-transform: translateY(-50%);
-ms-transform: translateY(-50%);
transform: translateY(-50%);
background-color: white;
}
<div class='outer-div'>
<div class='centered-div'>
Test text
</div>
</div>
