I am using react to build simple app, and using Materilize css. In my UserProfile Component class importing UserProfile.css import "./UserProfile.css.
/* UserProfile.css */
.custom-class {
margin-top: 30 !important;
color: pink;
}
UserProfile in render method have
<h1 className="custom-class">Title</h1> // Margin is not applyed, but color is pink
I have an option to
<h1 style={{ marginTop: 30, color: "pink" }}>Title</h1>
this works fine, but I prefer style code in css files.
I am not sure maybe that issue has no relation to overriding.
you should use px in css files, change your code to margin-top: 30px !important; and it should work.
And if you want to check overriding issues in css, you can inspect your code(with right click your browser and choose inspect) and check if its crossed or not.
You'll need to use camelCase for your classname, so .customClass instead of .custom-class.
Then your import statement should look like:
import css from './UserProfile.css`;
and in your component:
<h1 className={css.customClass}>Title</h1>
Read up on CSS Modules for more information.
You don't have a unit for margin-top in your css class
.custom-class {
margin-top: 30px !important;
color: pink;
}

I just started learning ReactJS and I made a Project with .scss
For some reason when I add a style in a .scss file that style also changes other components' styles as well.
example:
I add a li style in the Home.scss, but it will change the style of the Footer component's li too. I didn't import it into the Footer.js or anything.
Does anyone know what is the reason why does it do it, and what is the solution?
Adding a className per component won't solve your problem, it will work as expected until you have any nested component.
Because if you add
#component-name {
li {
...
}
}
The CSS will be applied to any component inside of that component too.
To limit your CSS to a component in react, you have a few options :
CSS Modules
Create React App supports CSS Modules out of the box (as of version 2)
It works with SCSS too (YourComponent.module.scss)
YourComponent.js:
import styles from './YourComponent.module.css'
export const YourComponent () => {
<ul>
<li className={styles.yourLi}>
</ul>
}
YourComponent.module.scss:
.yourLi {
color: blue;
}
CSS-in-JS
With this method, as the name suggests, you can declare your CSS within your JS.
There are multiple libraries to implement this.
Styled-Components
Here is an example with styled components which is the one that seems to be the most used as of today:
const YourLi = styled.li`
display: inline-block;
border-radius: 3px;
padding: 0.5rem 0;
margin: 0.5rem 1rem;
width: 11rem;
background: transparent;
color: white;
border: 2px solid white;
`
render(
<div>
<ul>
<YourLi>
Your styled li
</YourLi>
</ul>
</div>
)
Add a class footer in the first div of footer component
sass allows nested defining of classes like
.footer{
li{
}
}
using that can help.
since it doesn't matter where you import scss in react. styles are imported globally by default.
I am working on a quasar/vue app. I want to style the dialog popup within one component. I'm using scoped CSS, and if the CSS is not scoped, the style works. If the CSS is scoped, the CSS does not work. I only want to style this dialog in this one component.
The template code calling the dialog:
<div class="-nav">
<q-select
outlined
dense
v-model="select"
:options="options()"
behavior="dialog"
style="width: 100px"
/>
The CSS element is:
<style scoped>
.q-dialog__inner {
width: 400px;
background-color: red;
}
</style>
This does not work:
:deep(.q-dialog__inner) {
width: 400px !important;
background-color: red;
}
I noticed that the global quasar style is marked with !important
codepen: https://codepen.io/kiggs1881/pen/oNoOzEj
.q-dialog__inner > div {
width: 400px !important;
background-color: red !important;
}
hope it helps
Have you tried to put the parents class in front of the selector like this?:
(If have seen this here) and it worked for me inside an expansion item.
.q-dialog :deep(.q-dialog__inner) {
width: 400px !important;
background-color: red;
}
I think everything is provided in the quasar.dev documentation if that doesnt help try using on hover => funtion-To-Display-Popover-In-Specific-Component
there are many ways to counter this problem using scoped is not the only one
I understand similar topics have been discussed multiple times, but I couldn't find the solution to the problem I am facing.
I am trying to change the styles of PrimeNG in my angular app.
In my component, I changed .ui-inputext class of PrimeNG.
body .ui-inputtext {
font-size: 0.8vw;
padding:0;
background-color: #557db1 !important;
}
This is working only when I set encapsulation:ViewEncapsulation.None in my component class.
I also tried using :host >>>
:host >>> body .ui-inputtext {
font-size: 0.8vw;
padding:0;
color:red;
background-color: #557db1 !important;
}
Issue with using encapsulation:ViewEncapsulation.None in my component is that it changes styles of PrimeNGcontrols in the whole app.
I want to make changes to the control only for this component where I have modified CSS class.
Is there something else I need to do or maybe I am missing something here?
This issue was raised on GitHub here (https://github.com/primefaces/primeng/issues/1812) but it was not tracked further.
Try with :host /deep/ in your component css file.
Add one class to that input field and try to change css using that class rather than using the body and add encapsulation: Viewencaptulation.None in your component.ts file. It will not change other component css.
Here is the example code you can try like this:
<input type="text" class="field_input" pInputText placeholder="Username">
.field_input.ui-inputtext {
font-size: 0.8vw;
padding:0;
background-color: #557db1 !important;
}

I am very new to web development, and I cannot figure out how to solve the following issue, although it may be very easy.
I am using Angular 4 and Angular Material to implement tooltips like this:
<div mdTooltip="tooltip text" mdTooltipPosition="above">
<span>Show tooltip</span>
</div>
I would like to make the font size of the tooltip text bigger. However, I did not manage to find how to do this in the Angular Material documentation, neither searching in the web. Does anyone have any idea on how to do this? Thanks.
You can fix this by adding a .mat-tooltip css declaration in you main styles file and change the font size there. You need to set !important on the font size otherwise it won't show up.
Per the documentation here: https://material.angular.io/components/tooltip/api
And the spec: https://github.com/angular/material2/blob/master/src/lib/tooltip/tooltip.spec.ts
You can set the property 'matTooltipClass', as follows:
<div matTooltip="tooltip text" matTooltipPosition="above" matTooltipClass="tooltip">
<span>Show tooltip</span>
</div>
Then in your CSS (global - not for the component):
.mat-tooltip.tooltip {
background-color: darkblue;
font-size: 12px;
}
Also see their demo here: https://github.com/angular/material2/tree/master/src/demo-app/tooltip
Also keep in mind if you are using SASS, that the container for the tooltip is at the bottom and nowhere near where you are placing it in your component's HTML, so do not nest it in that component. Make sure it is standalone, otherwise it will not work. This note applies as well obviously to the comment above if you just choose to override .mat-tooltip
To see the changes, in developer tools, find the div at the bottom with the class "cdk-overlay-container". Then hover over the element. You can use your arrow keys to navigate into the element while you are hovered over to confirm whether your class is being added.
You can use css /deep/ selector.
For example:
/deep/ .mat-tooltip {
font-size: 14px;
}
Then you do not have to use !important
Add ng-deep before class name
Try this
::ng-deep .mat-tooltip {
background: red!important;
}
My problem was that using a globally defined css class-name such as .customname-toolip for matTooltipClass was NOT working. My solution below, and the !important was needed; set in the global styles.css file:
.mat-tooltip {
font-size: 16px !important;
}
add following code in your styles.css to increase its font size i.e. 12px
CSS
.mat-tooltip {
font-size: 14px !important;
}
and use matTooltip in your tag's as.
<p matTooltip="My Tooltip">...<p>
Try this way. It should work.
test.component.html
<div mdTooltip="tooltip text" mdTooltipPosition="above" matTooltipClass="myTest-tooltip">
<span>Show tooltip</span>
</div>
test.component.ts
#Component({
selector: 'test',
templateUrl: './test.component.html',
styleUrls: ['./test.component.scss'],
encapsulation: ViewEncapsulation.None,
/*
styles: [`
.myTest-tooltip {
min-width: 300px;
background-color: #FC5558;
font-size: 16px;
}
`]*/
})
test.component.scss
.myTest-tooltip {
min-width: 300px;
background-color: #FC5558;
font-size: 16px;
}
Use matTooltipClass to apply your custom class on tooltips
<button mat-raised-button
matTooltip="Adding a class to the tooltip container"
matTooltipClass="custom-tooltip">
Custom tooltip
</button>
Add your style in your component style.scss file
.custom-tooltip {
font-size: 20px !important;
}
You can set custom style only for your component by adding a custom class + using /deep/, which will apply the css changes only for your custom class and not globally.
for example adding a custom tooltip for an image tag :
<img
matTooltip="text"
matTooltipClass="my-custom-class"<----
src=""/>
and in the css file :
/deep/ .mat-tooltip.my-custom-class {<---
background: #FFFFFF;
}
I dont have an experience with angular but you may add a class or id for div. Then you may control with this class or id with css file.
<div class="sth" mdTooltip="tooltip text" mdTooltipPosition="above"> <span>Show tooltip</span> </div>
And
.sth{
font-size:20px;
}
in css file.
In v15, you can change css variables
body{
.mat-mdc-tooltip{
--mdc-plain-tooltip-container-color: #616161;
--mdc-plain-tooltip-supporting-text-color: white;
--mdc-plain-tooltip-supporting-text-font: Roboto, sans-serif;
--mdc-plain-tooltip-supporting-text-size: 12px;
--mdc-plain-tooltip-supporting-text-weight: 400;
--mdc-plain-tooltip-supporting-text-tracking: 0.0333333333em;
line-height: 12px;
}
}
Put this in your component css (or home component css if you want to apply it globally. note that putting this in your global css file won't work, and you have to put it in the home component css to apply it globally).
::ng-deep .mat-tooltip {
font-size: 16px;
}
I'm trying to change the style of the md-dialog.
in my main.scss i'm importing the prebuild pink-bluegrey theme...
then in my component I import the following -->
#import "#angular/material/dialog/dialog.scss";
$mat-dialog-padding: 0;
$mat-dialog-border-radius: 0.5rem;
$background: #ffffff;
#mixin mat-dialog-container {
padding: $mat-dialog-padding;
border-radius: $mat-dialog-border-radius;
background: $background;
}
#include mat-dialog-container;
The padding and border radius is correctly applied to the dialog window.
But the background is not working... also tried the !important statement.
I'm using this in a single component...
Is there also a change to apply those styles globally?
in chrome dev tools I see those applied style changes. The background gets overwritten by the pink-bluegrey theme..
hope anyone can help.
thanks
It is better practice to add a wrapper class around your dialog, and then add styling to the children. Have a look at this article for more information.
When you open your Angular dialog, you can add a panelClass
attribute, like this:
this.dialog.open(MyDialogComponent, {panelClass: 'my-panel'}).
then, in your css (e.g. in the root styles.css file), you can add the following:
.my-panel .mat-dialog-container {
overflow: hidden;
border-radius: 5px;
padding: 5px;
}
EDIT Warning
It is also possible to add the css to another file than the root styles.css, but then you have to use ::ng-deep in the css (e.g. ::ng-deep .my-panel{ // ... }). This is not advised, as ::ng-deep is deprecated in Angular
EDIT2 Good alternative
If you are using scss, then you can place your .my-panel-style in your mydialog.component.scss file, by using a #mixin, and #import the file in styles.scss. You can then use #include to load the defined mixin.
in your mydialog.component.scss file
#mixin myPanel(){
.my-panel .mat-dialog-container {
// css here
}
}
in your styles.scss
#import 'path/to/mydialog.component.scss' // you don't need the .scss suffix
#include myPanel();
I solved this problem by including this css block in the end of file material2-app-theme.scss
.mat-dialog-container {
overflow: hidden !important;
border-radius: 5px !important;
padding: 5px !important;
}
can you use css then change background in mat dilog, at i used color transparent
mat-dialog-container {
padding: 0px !important;
background: transparent !important;
}
