Template:Sticky header/styles.css

/* Template:Pp-template */ /**

* Make first row or thead element top sticky.
*
* Table classes:
* - sticky-header: sticky first row.
* - sticky-header-multi: sticky thead; headers moved via sortable + JavaScript.
*
* Tested:
* - Windows 10: (all skins) Chrome, Firefox, Edge.
* - Android Galaxy S21 (Minerva): Chrome, Firefox.
* - iPhone SE 2020 (Minerva): Chrome, Edge, Firefox, Opera, Safari.
* - Wikipedia Android app.
* - Print: Not styled.
* - No JavaScript.
*
* Notes:
* - Sortable moves to thead any header rows and (after sort) sorttop rows.
* - Sticky gadget (.mw-sticky-header) moves to thead any wikitable header rows.
*
* Issues:
* - Sticky in Timeless any width and other skins at <=639px width: tables wider
*   than content area overflow and horizontal table scroll lost.
* - Monobook <=550px width, can't override style:
*   body.skin--responsive .monobook-body {overflow: auto;}
