At first look at my codes:
JSX:
import React from "react";
import "./styles.scss";
export default function App() {
return (
<div className="App">
<h1> This is a Portfolio Item </h1>
<div className="item-container">
<div className="img-container">
<img
src="https://tf-react-chester.now.sh/images/portfolio-image-5.jpg"
alt="Portfolio 1"
/>
</div>
<h3>This is the Title of Item </h3>
<h4>
This is the description of Item. This is the description of Item.{" "}
</h4>
</div>
</div>
);
}
And CSS(SASS):
.App {
.item-container {
width: 100%;
height:auto;
.img-container {
position: relative;
$margin: 20px;
&::before{
position: absolute;
content: '';
**width: calc(100%-20px);
height: calc(100%-20px);** /* These two line don't work. */
left: 10px;
top: 10px;
background-color: #fff;
transition: all 0.5s ease-in-out;
transform: scaleX(0);
transform-origin: 0;
}
&:hover {
transform: scaleX(1);
}
img{
max-width: 100%;
}
}
}
}
I am trying to create a ::before animated content over the image. But when I am using calc() method it doesn't work at all.
What's the reason?
Note: I have tried some solution to the same problem from StackOverflow but those don't work for me.
This is the codesandbox link:CodeSandBox
Try with spaces ;)
width: calc(100% - 20px);
height: calc(100% - 20px);

I have the following code:
const CardContainer = styled(Flex)`
flex-direction: column;
padding: 12px;
width: 100%;
max-width: 450px;
height: auto;
border-radius: 32px;
overflow: hidden;
z-index: 1;
background: rgba(218, 228, 242);
box-shadow: 4px 4px 12px 2px rgba(black, 0.6);
transition: 0.2s;
&:not(:first-child) {
background: red;
margin-left: -50px;
}
&:hover,
&:focus-within {
transform: translatey(-1rem);
}
&:hover ~ &,
&:focus-within ~ & {
transform: translatex(50px);
}
`;
But the last statement is not working. The CSS code that I'm trying to copy is:
.card:hover ~ .card,
.card:focus-within ~ .card {
transform: translatex(50px);
}
And here is the original codepen:
https://codepen.io/toddwebdev/pen/yWMgQX?editors=1100
You need to do this instead:
& + ${() => CardContainer} {
transform: translateX(var(--distance));
}
Also your import styled from "#emotion/styled has to be import styled from "#emotion/styled/macro in order to support the above.
Note: changed the styled(Flex) to styled("section") to prevent errors in sandbox
import styled from "#emotion/styled/macro";
import "./styles.css";
const CardContainer = styled("section")`
flex-direction: column;
padding: 12px;
width: 100%;
max-width: 450px;
height: auto;
border-radius: 32px;
overflow: hidden;
z-index: 1;
background: rgba(218, 228, 242);
box-shadow: 4px 4px 12px 2px rgba(black, 0.6);
transition: 0.2s;
&:not(:first-of-type) {
margin-left: -50px;
}
&:hover,
&:focus-within {
transform: translateY(-1rem);
& + ${() => CardContainer} {
transform: translateX(var(--distance));
}
}
`;
export default function App() {
return (
<div className="cards">
<CardContainer>
<div className="card">

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:

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.
enter image description here
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.
in Plain JS I can say const corners = document.querySelectorAll('.corner') then I can add event listener to it.
My question is
Haw can I do that with react ?
Is it posibale to add on function in the parent <div> and program
it to add event listener for of its Childs
import React, { useState } from 'react'
import '../css/style.css'
function Boxshape() {
return (
<div
className='item'>
<div className='box'>
<div
onMouseOver={() => console.log('mouse over element A')}
className='corner A'></div>
<div className='corner B'></div>
<div className='corner C'></div>
<div className='corner D'></div>
</div>
</div>
)
}
export default Boxshape
this is my css just in case you are carries
.item{
height: 100px;
width: 100px;
position: absolute;
background-color: aquamarine;
}
.corner{
position: absolute;
width: 10px;
height: 10px;
border-radius: 5px;
background-color: black;
z-index: 2;
}
.A{
top:-1px;
left: -1px;
cursor: nw-resize;
}
.B{
top:-1px;
right: -1px;
cursor: ne-resize;
}
.C{
bottom:-1px;
left: -1px;
cursor: sw-resize;
}
.D{
bottom:-1px;
right: -1px;
cursor: se-resize;
}
Yes, you can attach an onmouseover event to the parent and retrieve the targets. Here is a plain HTML snippet, but you can translate this to React.
function logCorner(e) {
const targetClassNames = e.target.className;
if (targetClassNames.includes('corner')) {
console.log(`mouse over ${targetClassNames}`)
}
}
body {
padding:2rem;
}
.item{
height: 500px;
width: 500px;
position: absolute;
background-color: aquamarine;
}
.corner{
position: absolute;
width: 10px;
height: 10px;
border-radius: 5px;
background-color: black;
z-index: 2;
}
.A{
top:0px;
left: 0px;
cursor: nw-resize;
}
.B{
top:0px;
right: 0px;
cursor: ne-resize;
}
.C{
bottom:0px;
left: 0px;
cursor: sw-resize;
}
.D{
bottom:0px;
right: 0px;
cursor: se-resize;
}
<div className='item'>
<div class='box' onmouseover="logCorner(event)">
<div class='corner A'></div>
<div class='corner B'></div>
<div class='corner C'></div>
<div class='corner D'></div>
</div>
</div>
Depending on how complex your corner divs become you can adopt a variety of patterns.
Here is a simple example that abstracts the corner divs to a Handle component
function Boxshape() {
return (
<div className='item'>
<div className='box'>
<Handle className="A" />
<Handle className="B" />
<Handle className="C" />
<Handle className="D" />
</div>
</div>
)
}
function Handle({className}) {
const mouseOverHandler = () => {
console.log(`mouse over: ${className}`)
}
return (
<div
onMouseOver={mouseOverHandler}
className={`corner ${className}`}></div>
)
}
export default Boxshape
Yeah, you can pass in the event in the element tag, and then make a function (you decide the functions name), and then you can pass in the function into the element, by saying this.
don't do () cause we only log it once on click, also we put it in brackets, cause it's a js code, not a react.
function handleClick() {
console.log('Don\'t you dare click me lol')
};
<button onClick={handleClick}>I\'m a button</button>
I have been working on a simple application and i am trying to set an images a back-ground for my main page (the image cover all my background ) i have checked many answers that are on stackoverflow but i could not it correct, i wonder how to fix that ?
A screenshot
App {
text-align: center;
height: 100%;
background: url("N.png") no-repeat;
background-size: cover;
}
.App-logo {
animation: App-logo-spin infinite 20s linear;
height: 80px;
}
.App-header {
background-color: #222;
height: 150px;
padding: 20px;
color: white;
}
.App-title {
font-size: 1.5em;
}
.App-intro {
font-size: large;
}
#keyframes App-logo-spin {
from { transform: rotate(0deg); }
to { transform: rotate(360deg); }
}
class App extends Component {
render() {
return (
<div className="App">
<header className="App-header">
<img src={logo} className="App-logo" alt="logo" />
<h1 className="App-title">Welcome to React</h1>
</header>
<p className="App-intro">
To get started, edit <code>src/App.js</code> and save to reload.
</p>
</div>
);
}
}
export default App;
Set the height of the parent elements to 100% also.
html,
body,
#root {
height: 100%;
}
I apologizes in advance for this stupid question.
I created a series of components using the creat-react-app boilerplate. I imported them into the app.js and they render as expected but if I try move the components on the page using the app.css by giving my components an id tag. Nothing happens.
What am I missing? I thought that once you import the component you can just treat it as another html element on the page.
Again I apologizes for the simple question and grateful for any help.
As requested code:
one of my components;
import React from 'react';
import {Panel, Image} from 'react-bootstrap';

bootstrapUtils.addStyle(Panel,'main','backgroundImg');

I answered my own question. The answer is in two parts.
I needed to change the css position: fixed; to position: relative;
If I understand it right the css fixed position is basically the world coordinates of the web page and the css relative position is a local coordinate of the parent object.
To move the React component I created a <div> with the created React component inside of it and moved the <div> using CSS.
I have no doubt that there is probably a more elegant way but this is how I solved my issue.
