In this module, we'll explore the future of CSS and its intersection with emerging technologies like WebAssembly, PWA's, and CSS-in-JS libraries. We'll also delve into experimental CSS features and their potential impact on the web development landscape.

Future of CSS

- WebAssembly and CSS: How WebAssembly can enhance CSS performance and capabilities.

Syntax: wasm-module { ... }

Example: wasm-module { name: "my-module"; }

- PWA's and CSS: How Progressive Web Apps utilize CSS for enhanced user experiences.

Syntax: @media (display-mode: standalone) { ... }

Example: @media (display-mode: standalone) { /* styles for PWA mode */ }

- CSS-in-JS Libraries: The role of libraries like styled-components and emotion in shaping the future of CSS.

Syntax: const Button = styled.button;

Example: const Button = styled.button;

Experimental CSS Features

- CSS Nesting: Nesting CSS selectors for more efficient styling.

Syntax: & { ... }

Example: .header { &__title { font-size: 24px; } }

- CSS Scope: Scoping CSS styles to specific components or elements.

Syntax: :scope { ... }

Example: :scope { /* styles scoped to this element */ }

- CSS Color 4: Enhanced color manipulation and calculation capabilities.

Syntax: color-mix()

Example: background-color: color-mix(in srgb, red, blue);

Examples

- WebAssembly and CSS:

wasm-module {
  name: "my-module";
  css: `
    .header {
      background-color: #333;
    }
  `;
}

- PWA's and CSS:

@media (display-mode: standalone) {
  /* styles for PWA mode */
  .header {
    background-color: #333;
  }
}

- CSS-in-JS Libraries:

const Button = styled.button`
  background-color: #333;
  color: #fff;
  padding: 10px 20px;
`;

Best Practices
