Table Row Hover Effect
Hovering a cell tints its row, marks the row with an accent bar and faintly tints its column too. The row uses an inset shadow and the column a background, so the crossing cell stacks both.
Also known as: table row highlight on hover, table crosshair hover css, tr hover css.

}Customizing this snippet
- Color: set
--hfx-coloron the element or a parent. Currently previewing#3b82f6. - Base size: set
--hfx-size. Every other dimension is inem, so the whole thing scales together. Currently previewing16px. - Speed: change the duration on the
transitionoranimationshorthand. Staggered delays are relative, so they keep their rhythm. - Reduced motion: the rule at the end of the CSS turns the motion off for people who asked their OS for less of it. Keep it.
