Giovanni got it in one. Both of those are exactly my reasons for wanting borders on slots (and padding). The draft essentially creates a phantom container element, and I want to be able to *style* that container! > Summing up, I think that the following properties should be allowed > for ::slot: padding, border (including border-image), position (only > relative) and top/left/right/bottom/z-index, page break related > properties (to avoid breaking rows/columns). Can you expand on that last one? I understand the rest, but can't quite get what you'd use the page-break properties for. > Also I would like to see allowed by Selectors Level 4 the combinations > ::slot(a)::before and ::slot(a)::after, to insert text inside slots, > without inserting it into elements (that may have border / padding) Wouldn't work - ::before and ::after are siblings to their superior parent. You'd need ::inside first (and have it applicable to ::slot). ~TJ
