How To Add Inline Styles in Angular Components

Adding inline styles to components in Angular

If the Angular component is small and CSS usage is limited we can create the component with inline styles.

When we create a component in Angular, by default Angular CLI generates the component with external CSS file.

CREATE src/app/user-style/user-style.component.html (25 bytes)
CREATE src/app/user-style/user-style.component.spec.ts (648 bytes)
CREATE src/app/user-style/user-style.component.ts (291 bytes)
CREATE src/app/user-style/user-style.component.scss (0 bytes)
UPDATE src/app/app.module.ts (667 bytes)

Adding inline styles in Component Metadata

To create the component with inline styles in Angular, pass --inline-style flag to ng generate component command.

>ng generate component user-inline-style --inline-style 

If you see the output, no external file is created.

CREATE src/app/user-inline-style/user-inline-style.component.html (32 bytes)
CREATE src/app/user-inline-style/user-inline-style.component.spec.ts (691 bytes)
CREATE src/app/user-inline-style/user-inline-style.component.ts (282 bytes)
UPDATE src/app/app.module.ts (790 bytes)

ng generate component command created a component with inline style as show below.

@Component({
  selector: 'app-user-inline-style',
  templateUrl: './user-inline-style.component.html',
  styles: [
  ]
})

The inline style component metadata will have styles property, instead of styleUrls.

The styles property accepts an array of strings as value.

For example to style h1 tag of the component, we can directly add the necessary styles in string format.

@Component({
  selector: 'app-user-inline-style',
  templateUrl: './user-inline-style.component.html',
  styles: ['h1 { color:red }']
})

Incase if you want to add external style sheet, we can add it via styleUrls property.

A component metadata can contain both styles and styleUrls properties.

i.e., In Angular, We can create a component with both inline styles as well as external style sheets.

@Component({
  selector: 'app-user-inline-style',
  templateUrl: './user-inline-style.component.html',
  styles: ['h1 { color:red }'],
  styleUrls: ['./user-inline-style.component.scss']
})

And remember inline style will have more priority than external CSS style.

In the above example, If we add h1 color style in the CSS file it will have no impact.

//Inside user-inline-style.component.scss

h1 { color:green }

The h1 tag will be in red color only because, we have an inline style for that.

Adding inline styles in component template HTML

We can directly embed CSS styles in component template using <style> tag.

@Component({
  selector: 'app-user-inline-style',
  template: `
  <style>
      h1 {
        color:red
      }
    </style>
    <h1>Component with inline style</h1>
  `,
  styles: [
  ]
})

We can also use <link> tag to refer an external CSS file.

@Component({
  selector: 'app-user-inline-style',
  template: `
    <!-- relative URL of the stylesheet -->
    <link rel="stylesheet" href="../assets/user-style.css">
    <h1>Component with inline style</h1>
  `,
  styles: [
  ]
})

Summary

In this tutorial we have learnt different ways of adding inline styles to an Angular component.

  1. Adding in component metadata using styles
  2. Adding in template using <style> tag.
  3. Adding in component template using <link> tag.
