It’s not every day you can feel CSS be slow at something. Reddit user jgbbrd discovered nesting grid containers that all have 100% height can cause many-seconds of rendering delay. Probably not something you’ll ever have to worry about, but still, interesting. From the comments:

  • What a funny use of the NSFW tag!
  • This is not an issue when using 100vh instead.
