/*

|
* ShrinkVertically -- keep the board's horizontal scrollbar visible when columns
|
|
* are vertically collapsed (gear menu "collapse vertically" / shortcut, which sets
|
|
* localStorage vertical_scroll=0 and adds the class .board-task-list-compact).
|
|
*
|
|
* Kanboard core sets: .board-task-list-compact { max-height: 90vh; }
|
|
* That 90vh is measured from the top of the viewport and ignores the page header
|
|
* above the board, so column + header together exceed the viewport and push the
|
|
* horizontal scrollbar below the fold.
|
|
*
|
|
* We instead reserve a fixed pixel budget for the chrome above and below the task
|
|
* list (page header + board column header + the horizontal scrollbar + a little
|
|
* breathing room). A fixed-px budget is more reliable than a proportional vh value
|
|
* because that chrome is a fixed height regardless of screen size.
|
|
*
|
|
* The pixel budget is the --sv-shrink-offset CSS variable. It is injected in the
|
|
* page head from the plugin setting (Settings -> Shrink Vertically); when unset it
|
|
* falls back to 240px below. Increase it if the scrollbar is still clipped, or
|
|
* decrease it to make the columns taller.
|
|
*
|
|
* The selector is intentionally more specific than core's single-class rule, and
|
|
* uses !important, so this override wins even alongside a theme (e.g. Essential).
|
|
*
|
|
* The min-height override is essential: Kanboard's drag-and-drop sets an INLINE
|
|
* min-height on each column equal to its full content height
|
|
* (BoardDragAndDrop.js: css("min-height", parent().height())). In CSS, min-height
|
|
* beats max-height, so that inline value keeps tall columns from shrinking and our
|
|
* max-height alone does nothing. A stylesheet !important overrides the inline
|
|
* (non-important) min-height, so we reset it to 0 and let max-height win.
