Yesterday, I discovered a new wish I had in CSS: when selecting the next few siblings of an element, instead of having to do .el + *, .el + * + *, .el + * + * + *, I'd love to have something like :nth-next-sibling(-n + 3 of .el). But writing that down, the of made me think “Oh bother, that syntax would be confusing with :nth-child(n of .el)" and then the epiphany followed: I can achieve my goal with :nth-child already.
