Remove stylesheet only inside react app window - javascript

Image will best describe this:
code sandbox:https://codesandbox.io/s/annoying-stylesheet-2gpejc?file=/public/index.html
I'm writing React app inside non react app and their styles interfere with my React app styles.
How do I overwrite bootstrap-enterprise.css stylesheet only for the region of my React app without overriding the style rest for the rest of the page (The top app bar is theirs)
Edit:
.App {
all: revert;
}
worked initially, but then I tried it my real usecase (overrding Mui Textfield styling component) and it didn't. i edited the codesandbox for the exact case.

Since your React app is separated from the rest of the app, you could use the all css property to reset all the styles inside your React app before to write yours :
/* Affect all the elements under .App */
.App * {
all: unset
}
In your codesandbox, adding it at the top of your styles.css seems to work fine.

Is there any solution to these problems with Next.Js?

So i recently migrated from react to Next.Js, I am facing these issues and want to know if these have a solution :
Unlike react next can't just change a specific part of webpage and keep static part like navbar same throughout all my pages, I have to specifically add my Navbar component to all pages
The {styles.example} way of using css seems like a lot of work, I saw a lot of people using to do css within the js file, but it becomes a mess when I try to make it responsive. Is there any way i can use css just as normal like import it in js file, and use classname='example' in example.module.css
use _app
https://nextjs.org/docs/advanced-features/custom-app
import css in _app is global
https://nextjs.org/docs/basic-features/built-in-css-support
css extended
head(html way, won't apply loaders,make sure resource placed as refered): https://nextjs.org/docs/api-reference/next/head
import css (_app just like head but go webpack, named if not _app): https://nextjs.org/docs/basic-features/built-in-css-support
styled-jsx (inline,scoped by default, set global via prop): https://github.com/vercel/styled-jsx
element-style-prop: the react way
example cases
head in _app: compiled global css like bootstrap reset...
import css in _app: global custom css
head in component: compiled css for component, like date picker
import css in component: named fassion
styled-jsx: css fassion, scoped by default, global if global prop set
element-style: react fassion, element level

Apply css style to all primeng dialogs in my angular app

I am using prime ng dialog all over my angular application. I can change each specific dialog style by using ng-deep. For eg I have contact us page for which I have these files:
contact.html
contact.component.ts
contact.css
So I place the below css in contact.css and it changes the contact us dialog title bar color.
:host ::ng-deep .ui-dialog .ui-dialog-titlebar{
background-color: red
}
I want to do this for all the dialogs in my application, how can I do this? I placed the same css in style.css file in src folder and it didn't work.
So angular components by default employ a very handy strategy of Style Encapsulation which makes it so that styles don't bleed out into other components and cause unwanted effects.
You can utilize ng-deep like you have to allow styles defined within it to be inherited by child components of where it's specified.
However for things to be globally inherited you'll want to define them highest up in the order of inception so those styles cascade down to selectors below. In a default angular application that's not using SCSS or another pre-processor one of the easiest ways to do this is to add them to one of the first files initialized that hosts the child components such as index.html or app.component to allow components initialized afterwards to inherit them when they're rendered.
Hope this helps, cheers!

Problems adding custom CSS to Vuetify component

I'm working with the Vuetify selector input component, v-select, and I want to custom style it. Since the component renders with only one v-select and no necessary children in the html, I turned to styling the component via inspecting in chrome and copying down the class there. For example, to change the font size of the active value, I used:
.v-select__selections {
font-size: 20px;
}
This worked fine, until I realized my styles in this manner did not work on any parts of the (normally hidden) navigation drawer. For example,
.v-menu__content {
height: 500px;
}
Would not impact the styles in any way. Bizarrely enough, it was not simply my styles getting overwritten by Vuetify styles (!important had no effect) - it appeared that my CSS didn't reach the components at all. There was no trace of any of my written styles upon inspect. How?
I believe this is due to the active-based nature of the drawer-part of the selector component. Is there another way I should be addressing those kinds of elements in CSS? I wish I could provide a Jsfiddle, but (on the templates I've found), Vuetify renders completely differently. I'm using Vuetify 1.1.7.
My styles are included directly in the component .vue file, non scoped. Vuetify and vuetify styles are imported in main.js:
import Vuetify from 'vuetify'
import 'vuetify/dist/vuetify.min.css'
import 'material-design-icons-iconfont/dist/material-design-icons.css'
File structure (Default structure from vue init webpack -myProject):
src/
-main.js
-app.vue
-components/
-problematicComponent.vue
index.html
Edit: I also tried using deep selectors, but the problem still remained with the hidden menu components:
>>>.v-menu__content {
height: 500px;
}
Therefore the problem I have is different than the problem here:
Vuetify - CSS not working (taking effect) inside component
I once had a similar problem with the vuetify selector component using SCSS. Are you addressing .v-menu__content as nested inside .v-select? Because, interestingly enough, it isn't a child. It is at the same level as v-app (For whatever reason).
Make sure
.v-menu__content {
height: 500px;
}
isn't nested inside any other components in your SCSS.
while writing deep selector write like
.any_parent_class(can be any identifier) >>>> target_class{
}
i tried it with scoped selector , it worked.
like
.flex >>>> .v-menu__content{
}

React-Bootstrap and Bootstrap-sass modal.scss not loading

I have a react application, which uses react-bootstrap + bootstrap-sass.
I´m loading the bootstrap.scss file in my main app.scss like this:
#import '~bootstrap-sass/assets/stylesheets/_bootstrap';
In my page, I implemented a simple Component from React-Bootstrap.
But the modal window has no CSS whatsoever, so it looks really bad.
I´ve tried to load the modal.scss directly
#import '~bootstrap-sass/assets/stylesheets/bootstrap/_modals';
But still no styles are applied.
(the modal appears and hides as expected though).
Bootstrap scss is loaded though, as the styles on buttons, dropdowns, etc is present.
You you need to import the compiled CSS into the component JSX files that it applies to.

Vue.js modify other component's style

I am using Webpack with Vue.js to create a large-scale web app. The problem I encounter is the following:
I've am using vue-router and the following structure for the main app template:
<customNav></customNav>
<router-view></router-view>
The navigation is a single file component that has its own styles defined inside the component file. Let's say it has a black background by default. Now, on single occasions (when showing different views through the router), I want it to be transparent.
I thought I might just overwrite the CSS in the router view component, but this doesn't work because Webpack is bundling all the CSS of components I import, and I have to import all the components in the main.js to define them in the router. Therefore, overwriting the style in a component leads to it being the global default, even if the component is not even used.
How would I solve this problem?
You can take help of dynamic styling of VueJS. You can assign a class, based on the value of a variable. So in your customNav You can have two classes: say black-bg and transp-bg and you can change this will help of a variable: blackBackground
<YourElem v-bind:class="{ 'black-bg': blackBackground, 'transp-bg'!blackBackground}"></YourElem>
I think you can change this variable in two ways:
Have this as an instance data and change it based on current route.
Have this in vuex state and change in different components based on your requirement.
