Angular CLI have it's own way to initialize your global css/js.
They are located in .angular-cli.json configuration
Locate "styles": and add your css there
Example :
"styles": [
"../node_modules/angular2-busy/build/style/busy.css",
"styles.css"
],
Hope that helps.

Basically there are three different ways to do that :-
- By adding it to the "styles" array in angular-cli.json file as is shown by @penleychan in his answer.
"styles": [ "../node_modules/bootstrap/dist/css/bootstrap.min.css", "styles.css" ]
- You can directly import the css file into styles.css file (or any other css file) that is included in "styles" array in angular-cli.json file by adding the @import statement at the top of that file.
@import "~bootstrap/dist/css/bootstrap.min.css";
- Include the css file in index.html page by adding a link element.
<link rel="stylesheet" type="text/css" href="node_modules/bootstrap/dist/css/bootstrap.min.css" />
You can find a more elaborated explanation and a few more alternatives at this link
If you want to point to a css/scss file within a component, you can add a shortcut to your styles folder in your angular.json in the options node like so :
"my-app": {
"root": "...",
"sourceRoot": "...src",
"projectType": "application",
"architect": {
"build": {
[...]
"options": {
[...]
"stylePreprocessorOptions": {
"includePaths": [
"projects/my-app/src/styles" // path to your styles folder
]
}
}
},
}
},
Then, whenever you use @import "...";, it will start from the css folder, so you can use @import "theme.scss";
go to angular.json and include "styles": ["../assets/css/theme.scss","styles.css"],
Go to your angular-cli.json file and there is a property of arrays and you can add your css file in that place, just like I did with bootsrap.min.css.
An angular-cli project contains by default a styles.css file under the src folder of the project (myAngularCliProjectName/src/styles.css).
In this file you'll be able to add global styles and also import other style files.
There's no need at all to link them from the index.html file.
You can add you style file(i.e custom.css) at project root level(same level as styles.css) and then you can register it in angular-cli.json i.e
"apps":[
{
"styles":["style.css","custom.css"]
}
]
you can import CSS files in your global style style.css file.
@import 'custom.css';
So guys I was wondering since am still quite new to angular 7 I got some free html templates which came with alot of javascript files n css... How can I make those scripts work on the whole project as I want to use the template as a theme by breaking for my different components buh I need to make sure d scripts and css would work globally..
You can add a <script> in your HTML but IT WON'T WORK because while building the app the Angular DOMSantizer removes all the <script>.
So you have to load the custom js the way @trichetriche showed. But, if the js is required only for one component then there's a workaround which is kind of hacky.
You can load the js just after the DOM has been loaded/initialized in the ngAfterViewInit(). This way Angular DOMSantizer doesn't know about the <script>.
Here you go:
constructor(private elementRef:ElementRef) {};
ngAfterViewInit() {
var s = document.createElement("script");
s.type = "text/javascript";
s.src = "../path-to-your-js-or-external-URL";
this.elementRef.nativeElement.appendChild(s);
}
For more info, refer this: https://github.com/angular/angular/issues/4903
You can't.
But, you can add it in your application as a global script by addiing it in angular-cli.jsonfile :
"scripts": [
"assets/xxx.js", // path to assets file
"../node_modules/moment/moment.js" // Path to node modules dependency
],
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.
1: Configure angular.json:
"styles": [
"node_modules/bootstrap/dist/css/bootstrap.min.css",
"styles.scss"
]
2: Import directly in src/style.css or src/style.scss:
@import '~bootstrap/dist/css/bootstrap.min.css';
Alternative: Local Bootstrap CSS If you added the Bootstrap CSS file locally, just import it in angular.json
"styles": [
"styles/bootstrap-3.3.7-dist/css/bootstrap.min.css",
"styles.scss"
],
or src/style.css:
@import './styles/bootstrap-3.3.7-dist/css/bootstrap.min.css';
I personally prefer to import all my styles in src/style.css since it’s been declared in angular.json already.
Any CSS style file added to styles array at angular.json will be injected to index.html and will be a globally this mean any class added in these files you can use it inside any component.
another way is to add style file manually to index.html this work if the file host on cdn or in the assets folder.
Try the following:
@Component({
selector: 'app-my-form',
templateUrl: './my-form.component.html',
styleUrls: ['my-form.css']
})
Your file will be a SCSS file: myform.scss.
And then you can import an external css file like this:
@import "my-external-stylesheet.css"; // this on the top of `my-form.scss`
In the .angular-cli.json file of your child application look for the styles property of your app. Add the path to your parent CSS in there.
Here is an example of the JSON config.
"apps": [
{
"styles": [
"../../../../apec-template-bootstrap-responsive/src/main/resources/css/old-apec.css",
"styles.css"
],
}
],
This should give your child application any style you require from the parent.
