Storybook: Global styles applied to whole iframe - css

I am importing global styles in preview.js.
import '!style-loader!css-loader!sass-loader!../global.sass'
Unfortunately they get applied to the whole iframe's content.
Is there any way to import global styles which will not style storybooks elements but only my components?
I added the styles import to the angular.json. But this will result into the same problem.

Limiting CSS framework to Vue scope

I got a problem with the tailwind preflight. It's resetting some styles globally, which I really don't want it to. And disabling preflight would be a huge amount of work.
So, is there a way to use a css famework just inside the Vue.js scope without it affecting other styles of the page (I'm using Vue on top of an existing project)?
Importing it as usual:
import { createApp } from "vue";
import ImportConfig from "~/components/data_import/import_config/ImportConfig.vue";
import "~/styles/main.css";
Won't do the trick, cause the styles are accessible globally.
Also using VUe's custom-components ain't a proper solution cause these are using the shadow dom.

Why are the styles of my scss module being applied to the wrong component?

I'm building a website with gatsby and I have set up the gatsby scss plugin. Everything seemed to be working fine until I realized my styles from home.module.scss were also being applied to my navigation component that only imports navbar.module.scss.
I have a style for my buttons in each of these modules that looks like this...
button {
// different styles in the different modules
}
Both of these modules import a global scss file at the top like this...
#import '../styles/global.scss';
The react components only import their respective modules. In my main index component I import global styles like this import './global.scss'
Am I misunderstanding how scss modules work in React or is this is a bug?
from my understanding
In react importing SCSS or CSS in any component will be global.
So it will affect all other components as similar to the component where you imported the SCSS file.
use different class names

React and CSS Styling

In my page, I have to use two react components
Component1 and Component2
Page1 code
<Component1/>
<Component2/>
All the styling for components would come from the component CSS files. But for the page layout, I have page1.css
I would write selectors and classnames and define styles for page1.css.
There could be many pages and different layouts with similar classnames, how can we control the behavior of not having overriding styles.
You can use CSS module to apply the style to each component, it works so well, easy to manage code and it is local selector as well, so there is no conflict between 2 component.
Project tree will be like:
Component:
Button
Button.js
Button.module.css
Form
Form.js
Form.module.css
Avatar
Avatar.js
Avatar.module.css
Each component will have a unique css file to come with, so it is very easy to maintain the code when scaling up.
How to use:
create-react-app
Install css-loader
Create css file with add-on module at the file name ex: styles.css => styles.module.css
4.Import styles to component:
import styles from './styles.modules.css'
5.Add classname to JSX tag
<div className={styles.header}> Hello world</div>
Start styling your component by using normal CSS
You can use css specific to that component only:
page1.js
import './page1.css'
// page1 component
I suppose page1 component folder structure like:
page1/
page1.css
page1.js

React - Child componet stylesheet overwriting other child's stylesheet

I'm trying to apply separate styleSheets for every child component by importing different styleSheets in different components but fails to achieve this as styles are being overwritten.
Sample Code: Stackblitz
childa.jsx:
import React from 'react';
import "./childa.css"
export default () => <h1>Child A!</h1>;
childa.css:
h1 {
color: blue;
}
childb.jsx:
import React from 'react';
import "./childb.css"
export default () => <h1>Child B!</h1>;
childb.css:
h1 {
color: red;
}
This is just a sample code. Need solution for a project having large styleSheets.
Based on your clarification in one of your comments:
The thing is I'm converting a project from angular to react and all
the css is already written so I can't use inline style. Is there any
way in which I don't have to rename all the css classes in all the
stylesheets?
Short ans: You can't achieve that as of now.
This article explains all the different ways to style react components. In your case, the best that you can do is use css modules and rename generic classes like h1 to .h1.
Check this great article about css modules: Modular CSS with React.
Note: css modules are not available in create-react-app. If you must use it here's an
article on how to use CSS Modules with create-react-app.
I think this is caused by ther order of the imports.
In your parent component you have something like
import React from 'react'
import ChildA from './ChildA'
import ChildB from './ChildB'
This means that in the compiled code you'll have the two stylesheets imported one after the other, and the second h1 rule will overwrite the first
You should use classes for your components, or use inline style
Importing a css does not wrap it in the scope of the component is just a straight import into the DOM. In order to mantain a separation of components styles you have to approach with another solution, as styled-components.
This may not work for your entire application, but I fixed it by applying a class to the element (.childA and .childB). This solved the problem.
export default () => <h1 className='childB'>Child B!</h1>;

how to override react-bootstrap with custom css file

I use react-bootstrap, but I want to modify some of the elements, so I wrote my own custom.css. However it doesn't make any changes (only when I put !important, but the file is so large so it's not a good option).
import {MenuItem, Nav, Navbar, NavBrand, NavDropdown, NavItem} from "react-bootstrap";
import {LinkContainer, MenuItemLink} from "react-router-bootstrap";
import '../assets/css/custom.css';
This is what I did so far.
When are you importing the Bootstrap CSS? I have an app which successfully uses Bootstrap with some overrides, which does this at the top of its index.js:
require('bootstrap/dist/css/bootstrap.min.css')
require('./bootstrap-overrides.css')
