Episode notes
Shadow DOM Basics
- The Shadow DOM encapsulates UI elements, logic, and styles, simplifying complex structures.
- Default browser elements like
<video>and<audio>utilize the Shadow DOM, containing internal elements and functionalities.
Styling Shadow DOM Elements
- Browser Shadow DOM elements are hard to style, often requiring vendor prefixes like
-webkit-appearance. - Styling inputs, selects, and other default elements involves these workarounds due to their Shadow DOM nature.
Creating Custom Shadow DOM Components
- Create your own Shadow DOM components for functionalities and styles that don't leak over into your main code.
- Encapsulation prevents class overrides and maintains consistent behavior, ideal for reusable UI elements.
