| static | Default value. Elements render in order, as they appear in the document flow | |
| absolute | The element is positioned relative to its first positioned (not static) ancestor element | |
| fixed | The element is positioned relative to the browser window | |
| relative | The element is positioned relative to its normal position, so "left:20px" adds 20 pixels to the element's LEFT position | |
| sticky | The element is positioned based on the user's scroll position
A sticky element toggles between |
|
