How do you overwrite CSS Modules in React for nested components? - reactjs

As my first React Project, I want to create a DatePicker component and I would like to use CSS Modules.
However, CSS Modules generates a unique class and I would like to know if it is possible for the user to customize a nested component for example ?

What is a nested component in this case? CSS modules will encapsulate your styles, you can still write any kind of valid CSS in that file..

Multiple Inline stylesheets

enter image description hereI am using React, Typescript and Styled components. Everything looks fine but I am seeing multiple styles tag under my head tag. I would like to know why it is creating multiple styles tag and is there any way to combine all styletags into one.
For example , I am creating a dropdown in a loop and it has 3 values and it generates 3 style tag under my head tag
Thanks all
From what I understand, I believe this is expected behavior assuming you're utilizing style partials for each component. React (and other front end frameworks like Angular) is importing the styles that apply to the current view. It does this by importing them individually as the page renders different views.
This isn't always ideal, though. I often create CSS partials in a global styles folder if I want to share styles across components. The only styles I put in the component specific CSS file are styles that are 100% specific to that component and I don't ever want to share.
You could also always create a shared CSS file that you import once - ie - dropdown.css (or .scss etc if you're using a pre-processor) and delete the react component specific CSS files that you will be replacing with this new global version. The downside being that whatever CSS you have in there will always be imported even if the dropdown isn't being rendered or viewed.

Hot to use custom CSS with Material UI and NextJS

I am try to add some CSS to my components. However, when the website renders the custom CSS is always removed. I am styling my own pages and do not override the CSS of third parties, at least not consciously. I am using Material UI and NextJS and realised that while following this
that all server-side CSS is removed. I suspect that this is the issue, but not sure how to work around it. The CSS is just custom to the component and follows the naming convention of Next :
[filename].modules.css
Does anyone know what do do?

Inject custom React component

On a React app, a client needs to customize some pages for some specific needs.
Is it possible to inject some custom JS / React component and "override" the behavior of an other component?
I don't want to keep the custom component on the bundle all the time and do some control because other clients may customize other features as well ...
Basically, I'm trying to inject a custom JS with a custom component inside and use it.
Anyone had to do samething like this?
In my company we had kind of the same problem and it can get very messy. You can use window.eval() if you import an external js code to make it run in your project but I would not recommend it at all as it gave us a lot of headaches...
That would be for JS code which are instructions and not components.
If your client has their own components maybe you can suggest them to create a node library so you can import their comps.

CSS Modules: is there a way to reuse react component with different styles

React with CSS Module is very delightful, anyway, I have a page on which I want to represent exactly the same components except styling, I do not know how to do this with CSS Module.
In a traditional way, I would like to use different css file links in the "head" on each page, but CSS Modules is bound within it is own component by importing styles, seems there is no way to overwrite it without ruin the other page.
Of course, I can just copy all components and paste in another folder, and import them there, re-write the css files, but a full copies of component seems silly, what if I want to modify any component in these components? then I have to modify all copies.
Is there a graceful way to do this?
Thank you.

Restrict imported CSS to given component

I am currently building out the admin side of my first React app, which was started with create-react-app (also styled-components if it matters in this case).
Instead of building out my own custom admin I'm using Semantic UI React. Part of this involves importing the styles:
import 'semantic-ui-css/semantic.min.css';
I'm doing this in my admin container component. The problem I'm running in to is that once I import those styles the global selectors are applied site-wide, even though I only want them in the admin side of things.
Is there a standard practice for restricting imported styles to a given area of your app? I'm pretty unfamiliar with this.
You need to use a style loader supporting CSS modules spec.
This loader would namespace your component's css classes with a parent unique class. This would prevent your css classes from leaking to global namespace.
Example, I had used isomorphic style loader from kriasoft which did this.
