Question: I'm trying to build a static site using Angular. What I want is to have some global css/js/image files to be added to the `index.html`

This is my code in `index.html`

```
<link rel="stylesheet" type="text/css" href="css/layers.css">

```

My `css` folder in in the same level as the `index.html` file

I'm getting this error for each stylesheet I added (from ng serve with chrome)

> 
> Refused to apply style from '<http://localhost:4200/css/layers.css>' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.
> 
> 
> 

I've tried adding this too

```
#.angular-cli.json
"styles": [
        "styles.css",
        "css/layers.css"
      ],

```

How can I fix this?

My angular setup is

```
Angular CLI: 1.6.5
Node: 8.1.4
OS: darwin x64
Angular: 5.2.2
... animations, common, compiler, compiler-cli, core, forms

Answer: 
in your angular.json, add the config option

> 
> "extractCss": false,
> 
>

like this

```
"options": {

        "aot": true,
        "outputPath": "dist",
        "index": "src/index.html",
        "extractCss": false,
        "main": "src/main.ts",
        "polyfills": "src/polyfills.ts",
        "tsConfig": "src/tsconfig.app.json",
        "assets": [
          "src/favicon.ico",
          "src/assets"
        ],
        "styles": [
...

```
Step 1:
Update your angular.json with the below details.

```
        "styles": [
          "./node_modules/bootstrap/dist/css/bootstrap.min.css",
          "src/styles.css"
        ],
        "scripts": [
          "./node_modules/jquery/dist/jquery.js",
          "./node_modules/bootstrap/dist/js/bootstrap.js"
        ]

```

Step 2:
Make sure the index.html DONT have the "css" and "js" imports/references.
