In my case the reason was trivial, but actually took a lot of time to find.
Styles were not working, because I was putting them in the styles attribute under test section.
Make sure you add styles under build section.

You can also leave the .angular.cli.json like as it is
"styles": [
"../node_modules/bootstrap/dist/css/bootstrap.css",
"../node_modules/font-awesome/css/font-awesome.min.css",
"../node_modules/primeng/resources/primeng.min.css",
"../node_modules/primeng/resources/themes/omega/theme.css",
"styles.scss"
],
The order of the styles matter. In the above example. Bootstrap css will be applied first followed by primeng themes and finally your custom scss file. Eventually, styles.scss will override all other styles. And no need to import any where.

How to include custom styles with Angular CLI - Stack Overflow
angular-cli how to add global styles? - Stack Overflow
As per your folder structure, correct path is assets/css/styles.css so change it in your angular-cli.json file as below and check it.
"styles": [
"styles.css",
"assets/css/styles.css"
],
Simplest way is to create a folder (in src/) call it styles/ place your style.css (or SCSS and all other _variables.scss files) in it then amend angular-cli.json thus:
"styles": [
"styles/styles.css"
]
As of the beta.14 release of the CLI (which uses Angular 2.0 final), a global stylesheet can be linked inside angular-cli.json under the "styles" key. This is a reference to a file relative to the src/ directory, which is style.css by default.
Leveraging this method you could:
- Copy the global styles into
src/styles.css - Use CSS imports to import external rules into
styles.css - Add more global styles via the
apps[0].stylesproperty inangular-cli.json
See also Global Styles in angular-cli's wiki.
Sounds like a CSS selectivity conflict between your linked CSS file and the compiled CSS in JavaScript that Angular places as Embedded CSS in the head or your web page, but which is stored in the memory of the browser.
This is why I always recommend you stop using Angular's poorly designed embedded CSS system and use linked CSS only. To do that you need to change your Angular JSON Setting file to remove the Embedded Style sheet, then Add a Setting to Tell Angular to copy your Linked CSS to the "dist" folder so your HTML link can access it. But see below for details...it helps to understand how CSS works in Angular. It is NOT intuitive!
HOW CSS WORKS IN GOOGLE ANGULAR
For starters, none of the above answers explains what is REALLY going on in Angular's CSS system or why you might be seeing cascading problems. In an Angular project, when you add styles paths directly into the "angular.json"(newer) or "angular-cli.json"(older) settings file, Angular grabs all those CSS files, compiles them into a JavaScript file, then spits them out as embedded styles in the head of your HTML file:
This angular.json setting:
"styles": [
"src/styles.css",
],
Gets turned into HTML and added to a gigantic embedded <style> tag that JavaScript creates in the DOM of your browser:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>My Project</title>
<style>
.mystyle {background:blue;}/* everything in styles.css gets dumped in here! */
</style>
<body>
...
Bad CSS design! You can only see this if you go to a browser and use F12 and look at the actual DOM and CSS angular spits out in memory in your browser. If you use component styling, the same thing happens when those components get loaded into the DOM by Angular modules, etc. They get dumped into ANOTHER embedded style element under the first one.
I'm not 100% sure the Angular guys understood what they were doing adding embedded styles like this. Any CSS in your linked styles could be hidden with these embedded style systems Angular uses if they are inserted AFTER your linked styles.
One of the things I don't like about Angular is if you place CSS IMPORT tags inside your "styles.css" file (for example to bootstrap), the compiler also grabs those and spits those out into these embedded style tags, as well. Traditionally, importing one style sheet into another was used to control cascade order as imported sheets were inserted before other styles in the parents page. We use @import to hide styles that are not supported in very old browsers, and manage large libraries of styles by function this way. Because Angular ignores all that now and jumbles all this CSS together, you're left with a gigantic embedded inline style block in the head of your "index.html" file, and its very difficult to control cascading orders this way.
Angular's style system also doesn't support skinning of websites or themes using this inline system, nor global caching of linked styles between pages which would save bandwidth. And it doesn't matter WHERE you put your style sheets in your folder structure, as people above mention. If they are referenced in the angular.json, they all get compiled into these embedded style blobs at the head of your page in an order you cannot control.
For that reason, I recommend you REMOVE ALL STYLE REFERENCES FROM "ANGULAR.JSON"! Then add them back into your "index.html" manually as links like this:
<link href="styles/styles.css" rel="stylesheet" />
...then changing your angular.json settings file by removing the styles entry in your styles array path list then pasting it back into your assets array list so Angular knows where to migrate your CSS folders and files in the dist folder, like so:
"assets": [
"src/styles",
],
"styles": [
],
When you now compile your Angular application, JavaScript ignores your CSS file (in terms of compiling it with the JavaScript and later building it into a <style> CSS block) and instead pushes that file as a plain vanilla resource CSS file into your "dist" folder of files. When you push that to production, your <link> CSS tag can now send that CSS file to the user's browser, which is normally how most websites deliver CSS in websites today.
Your Angular application is now using just <link> or external CSS files for styles in your index.html file rather than <styles> or embedded CSS. You can still use this internal or "embedded" Angular-managed CSS system. I am not 100% against it. In rare cases, embedded CSS was great for supporting offline web pages. Angular has a nice system for controlling and manipulating CSS this way. But it is just not traditionally how CSS was used in most caching systems the past 20 years. Using "external" or <link> CSS, your main styles are now stored in the user's "native" browser cache for much longer periods of time, saving bandwidth and rendering/paint speed in the browser.
<link> CSS gives you back complete control of your websites styling, cross-browser fixes, skins, etc. Your front-end designers also have control over it and updates are independent of kooky polyfills, preprocessing, scripting dependencies, etc. You also now gain back full control of your cascade order, which is critical if you want full control over that.
Linking external styles also has huge caching advantages over Google Angular's broken CSS system, as the browser's naturally cache all this on page refreshes or revisits. We've been using CSS this way since the 1990's so Im baffled why Google went back to an old inline style system. Linked styles are just superior for managing and caching css. We also add versioning query strings to the end of linked CSS files (/mystyles.css?v=1.2) so you can force refreshes, etc. Again to do this, REMOVE all references to CSS in the angular.json file and manually add them in as links in the head of your index.html file.
I do think you can safely use the Angular's modular or component-based styling system as long as you understand that when you lazy load or preload Angular modules those embedded style elements do get pushed down from the server to the user on every new visit or refresh of the script block. Also understand that way modern browsers work today is not how older ones worked.....new browsers do not parse embedded styles after linked ones, but honor the order you inserted them into the head of your HTML page. In other words today, the order you put them in the page could be unpredictable in Angular when it finally delivers the HTML. Cascade order is today now heavily controlled by the HTML designer, not the W3C recommendations.
I think that's the main purpose of Angular's modular styling system....to take over control of CSS away from the designer and hope they don't notice. But to be honest, its unnecessary if you use external sheets and follow basic cascading rules.
No need to update or reinstall your bootstrap just do below mentioned step it will work for you
open angular-cli.json inside styles array and specifying the path of bootstrap like this:
Angular-cli.json:
"styles": [ "./node_modules/bootstrap/dist/css/bootstrap.min.css", "styles.css" ],Open your style.css and paste this at the top:
@import url("../node_modules/bootstrap/dist/css/bootstrap.min.css")
In your style.css add following line of code on top and let us know.
@import url("../node_modules/bootstrap/dist/css/bootstrap.min.css")
Also check with following line too
@import url("./node_modules/bootstrap/dist/css/bootstrap.min.css")
Hope it will help.
The styles array inside of the angular.json file is used to declare global styles for a project (styles.css being one).
If you import all of your other stylesheets into styles.css (and styles.css is specified in the styles array in angular.json), you'll end up with one global, composite stylesheet.
If you put all of your stylesheets into the angular.json styles array independently (rather than importing them into styles.css), you'll end up with multiple global stylesheets.
In angular.json
The styles.css file allows users to add global styles and supports CSS imports.
You can add more global styles via the styles option inside your project's build target options in angular.json. These will be loaded exactly as if you had added them in a <link> tag inside index.html.
Importing css files in styles.css enable you divide your css code into separate files for the sake of organize code

Late to the party, I had the same issue and I should've justed looked at the console, for us it was that we applied a default content security policy like so
<meta
http-equiv="Content-Security-Policy"
content="
default-src 'self';
script-src 'self';
frame-src 'self';
img-src 'self';
connect-src 'self';
style-src 'self';
font-src 'self';
"
/>
Which is the root problem,
Angular (at least in development / by default) uses unsafe-inline scss
For development you can just set it to allow for unsafe-inline
<meta
http-equiv="Content-Security-Policy"
content="
default-src 'self';
script-src 'self';
frame-src 'self';
img-src 'self';
connect-src 'self';
style-src 'self' 'unsafe-inline';
font-src 'self';
"
/>
for production it's recommended to generate the nonces, more info:

The angular app (v9) I'm working on has a bunch of different styles included.
In angular.json, in the options.styles array, I have something like:
"styles": [ "src/styles.sass", "node_modules/font-awesome/css/font-awesome.css", "vendor/roboto.css", "node_modules/dragula/dist/dragula.css", "node_modules/ng2-daterangepicker/assets/daterangepicker.css", "node_modules/@browsingagain11/my-ui-library/dist/assets/my-ui/styles/style.css" ],
And then in for example, src/styles.sass, I have a bunch of imports at top, including @angular/material/theming
Does having something lower in the styles array have priority over styles defined higher up in the array?
Also, an issue I'm running into is that the material design typography and designs are being overwritten by the typographies defined in the my-ui-library style.css file.
I wanted to keep typography of material design, so I removed the css style from the styles array and instead imported into my single component that wanted those styles: @import url('~@browsingagain11/my-ui-library/dist/assets/my-ui/styles/style.css')
But now I experience issues where things like icons from my-ui-library do not display and I believe its because styles higher up are cascading down.
Css is hard..
Edit:
Just to clarify a bit, when I include
@import url('~@browsingagain11/my-ui-library/dist/assets/my-ui/styles/style.css')
in my angular.json file styles array at the very bottom, the icons from this library end up showing. When I'm viewing source, icons and color gradients shown in ::before and ::after selectors show as expected (except font style size is a bit weird but thats another story..)
The problem of doing this addition to the styles array is the typography it introduces overwrites the typography that the site originally used (which was from material design).
If I were to instead remove the import and try and containerize it inside the component styling using:
@import url('~@browsingagain11/my-ui-library/dist/assets/my-ui/styles/style.css')
at the top of the component styles file, things like typography from this import seem to be working within this container. But, the ::before and ::after selectors are not showing at all.
It seems very convoluted using 2 different libraries that seem to overwrite each other, but we are in the process of migrating styles over and we haven't finalized designs for all components. So I'm trying to containerize styles in the specific components themselves. But they do not work as intended.
