Placement anchored to the viewport or window rather than the document flow. Reserve enough content space so the fixed region does not cover essential controls.

When to use it

Use it for persistent navigation or actions that must remain available during scrolling.

Know the difference

Fixed elements do not scroll with content; sticky elements initially participate in normal flow.
