the discord widget is added with JS but it hovers with CSS with the following CSS (I took the selector out of a long list in the actual CSS file):

box-shadow: var(--Bs3BigHoverShadow) !important; transform: var(--Bs3BigElevation) !important; }
 * 1) WikiaRail > section:hover {

The CSS makes it so that any box in the wiki rail elevates upon hovering.
