How can I make the height and width of a div grow and shrink with their aspect ratio while resizing the window?. I'm using tailwind css with next JS and I want to make my div responsive while resizing the window, and in doing that I need the height to shrink as well. how is that possible?
<div className="relative flex -z-10 h-auto w-72 object-scale-down">
<Image src={"/profile.webp"} fill objectFit="cover" />
</div>
I'm using an image as a content for the div.
I am trying to render a Chart JS canvas via a slot;
chartWrapper.html
<template>
<div class="chart-wrapper">
<slot name="chart"></slot>
</div>
</template>
chartWrapperContainer.html
<c-chart-wrapper>
<canvas slot="chart" class="donut" lwc:dom="manual"></canvas>
</c-chart-wrapper>
The chart does not render and the canvas in the rendered Markup shows 0 width and height. Rendering without the slot works well; I need to wrap it into a slot for structural reasons.
What could be wrong with this?
This was sorted out by wrapping the canvas in a div; made some logical sense to me not to push a plain 'photo' into a slot whose internals it's unaware of.
<!-- chartWrapper.html -->
<template>
<div class="chart-wrapper">
<slot name="chart"></slot>
</div>
</template>
<!-- chartWrapperContainer.html -->
<c-chart-wrapper>
<div slot="chart">
<canvas class="donut" lwc:dom="manual"></canvas>
</div>
</c-chart-wrapper>
Alternately, you could set a CSS property that defines the Custom Element as a block, or inline-block through the :host pseudo-class. (By default a custom element has its display value set to inline.)
Then you can set its height and width or let the default ones:
<!-- chartWrapper.html -->
<template>
<style>
:host {
display: inline-block ;
width: 50% ;
height: 200px ;
}
</style>
<slot></slot>
</template>
I want to use ng-tags-input in my project.
I try to set diffrent color for each tag according to color property object in array.
Here is plunker I am working on.
For this purpose I need to override tag-item css class in ng-input template.
Here is the example of ng-input template:
<script type="text/ng-template" id="tag-template">
<div class="tags-input" ng-style="{background: data.color}">
<span>{{$getDisplayText()}}</span>
<a class="remove-button" ng-click="$removeTag()">✖</a>
</div>
in this row I try to override tags-input css class:
<div class="tags-input" ng-style="{background: data.color}">
And here is result I get:
as you can see on left and right edges not colored.
Any idea what I am doing wrong?And how to override the tags-input css class??
If you look at the markup, you'll see that the .tags-input div where you apply your background color style is embedded into an li element, which has a laft and right padding of 5px. That's why the color is not applied on the full width of the button.
So, make sure to apply your own stylesheet after the ng-tags-input stylesheet, and override some CSS rules in order for the lito have no padding, and for the div with the background color to have a padding instead:
/* override default tag styles for colors to look less ugly */
tags-input .tags .tag-item {
padding: 0;
height: 27px;
}
.tags-input {
padding: 0 5px;
border-radius: 2px;
}
Here's your plunkr modified to make that happen.
I would like to set the width of an element using ng-style and a media query.
I have tried this:
{'width' : #media (max-width: 480px) ? '70%' : '90%' , 'border-radius': '6px', 'background':'#F5F2ED'}
But it doesn't seem to work.
Any ideas?
There is a trick to this problem,
create another inner <div> in your outer <div>
It works because you can reverse the effect of your applied style, by setting the values as 0, none or initial.
Example:
The effects you want for your<div>
IN TS: setting background-color according to the data parsed in from parent. (unable to do in CSS)
IN CSS: no background when the screen width is larger than 1024px (you do not want to check width to change accordingly in TS)
The problem you faced is that:
When using [ngStyle] to set the style, it will overwrite your media query for devices larger than 1024 px.
The solution is that: you create a inner div and set the css as:
outer div | color according to the data parsed in, use [ngStyle]
max-width | more than 1024 | less than 1024
inner div | background-color : white | background-color : initial
In your HTML
<div [ngStyle]="'background-color':color[2]">
<div class="inner">
some component
</div>
</div>
In your CSS
.inner{
background-color: white;
}
#media (max-width:1024px){
background-color: initial;
}
In your TS
#Input() color
This will reverse the effect or set it to none so that outer div color can be applied.
Also, note that the CSS for inner div for more than 1024px should be your default website theme background, so change to anything which is your default background.
Because they are in different div outer div cannot overwrite inner div.
Let's see to this directive source:
var ngStyleDirective = ngDirective(function(scope, element, attr) {
scope.$watch(attr.ngStyle, function ngStyleWatchAction(newStyles, oldStyles) {
if (oldStyles && (newStyles !== oldStyles)) {
forEach(oldStyles, function(val, style) { element.css(style, '');});
}
if (newStyles) element.css(newStyles);
}, true);
});
There is nothing to support this functionality.
I started to use Angular Material in my project and I was wondering how I can change the svg color inside an am-button.
This is my code:
<md-button class="md-fab md-primary">
<md-icon
class="ng-scope ng-isolate-scope md-default-theme"
style="height: 14px; width: 14px;"
md-svg-src="img/material-icons/core/arrow-forward.svg"
></md-icon>
</md-button>
What do I need to add to change the color of the svg from the curent black to white, just like in Google's button demo? (section "Icon button using Font-icons")
I'm on angular-material 0.8, and I simply added
style="color:white;font:bold;"
to the md-icon element.
For the people trying to color their md-icon, I found out that I had the same problem using Angular 1.3.x and Angular Material 0.8.x.
I fixed the problem by editing my SVG files and deleting the "fill" attribute that was overriding any inherited color.
After deleting this "fill" attribute in each SVG file, I could properly choose the color I wanted to assign to the icon thanks to CSS as specified by Jason Aunkst.
The SVG is under the md-icon, so you could add this to your style:
md-icon {
color: red
}
md-icon svg {
fill: inherit;
}
The following is the only way I've gotten it to work via stylesheets.
md-icon {
svg {
path {
fill: #ffffff;
}
}
}
Am using this in the CSS :
.my-icon svg
{
fill : #fff;
}
And in the HTML :
<ng-md-icon icon="search" class="my-icon"></ng-md-icon>
Works fine!
You should be able to do this by add "fill:white" to the style of the icon.
<md-icon class="ng-scope ng-isolate-scope md-default-theme" style="height: 14px; width: 14px; fill:white" md-svg-src="img/material-icons/core/arrow-forward.svg"></md-icon>
Add this to your css:
svg {
fill: inherit;
}
The svg will now inherit the fill attribute of your md-icon
<md-icon style="fill: red;" md-svg-src='/img/ic_menu_white_24px.svg'></md-icon>
I was having a similar problem when trying to change default svg icon color. For those who are experiencing the similar issue, make sure you check the angular-material version you're currently using. Currently, I'm using the angular-material "0.7.1" and this is quietly important.
NOTE: with my current Angular-material (0.7.1) version, the <mdIcon></mdIcon> directive only checks to see if attr.Icon is defined or not during postLinking compileFunction. With this implementation, in order to reference your svg icon files, you simply add icon attribute to your <mdIcon icon="iconsDir/path_to_icon_file.svg"></mdIcon> element directive. Notice in the earlier angular-material version, you might have use md-src-svg for referencing your svg files, its no longer the case in 0.7.1 version.
So if you were using 0.7.1 and following above instruction, you should have your svg icon rendering correctly, now its time to change the background-color of the svg you're using.
Raw svg file before any modification:
<svg version="1.1" xmlns="http://www.w3.org/2000/svg" x="0px" y="0px" width="24px"
height="24px" viewBox="0 0 24 24">
<g>
<path d="M6,2C4.9,2,4,2.9,4,4l0,16c0,1.1,0.9,2,2,2h12c1.1,0,2-0.9,2-2V8l-6-6H6z M13,9V3.5L18.5,9H13z" />
</g>
You should have a folder within your project where you save all your svg icons, in my case, I have a folder named icons where I store all my svg icons. The example svg file above is the non-modified svg icon where I got it from https://github.com/google/material-design-icons. (Default its rendering as a black svg file)
To change the default svg file, you would simple add a fill attribute to your raw svg file. See modified svg file version:
<path d="M6,2C4.9,2,4,2.9,4,4l0,16c0,1.1,0.9,2,2,2h12c1.1,0,2-0.9,2-2V8l-6-6H6z M13,9V3.5L18.5,9H13z" fill="green" />
I simply added fill="green" the path element svg file, and now my svg icon is rendering as color green instead of default black. I know some of you guys might be using a different version of angular-material, but the mechanism of changing default svg color should apply the same. Hopefully this can be helpful to solve your problems, thanks!
The issue seems to be with the downloaded SVGs from Google Design icons as they override the fill attribute in the svg root. Compare the view source of SVGs on Google Design with the ones used in the example.
Solution:: Override fill in css.
md-icon svg {
fill: currentColor;
}
One way to do it is by setting a custom class selector.
HTML:
<md-button class="md-fab mybtnstyle">
<md-icon md-svg-src="img/icons/cake.svg"></md-icon>
</md-button>
CSS:
.md-button.md-fab.mybtnstyle {
background-color: blue;
}
.md-button.md-fab.mybtnstyle:hover {
background-color: red;
}

Easiest way out
Now there's no need to change the svg or the fill property.
Simply add the !important to md-icon's color property in CSS:
md-icon {
color: #FFF !important;
}
I was having a similar problem, I needed to change the SVG color using CSS, but I also needed to keep the original SVG color (e.g. fill="#fff") when no CSS was supplied.
I enhanced Jason Aunkst's approach to make it work. Here's the solution:
md-icon[style*="color:"] svg [fill] {
fill: inherit;
}
That class will set any svg's child element with a fill attribute to inherit the color value as long as the svg is a child of an md-icon element that contains the style attribute with a color value.
It will only work on SVG's that are only using one fill color though. Adjust as needed, hope it helps!
