I don’t really know what to say, it’s cool if you can highlight things but this looks like an editing glitch.
It is actually an HTML mechanic I discovered while (trying) to make my own website, then decided to use in the forums.
If you surround the word “ins” by <>, then all text afterwards will be highlighted in green. If you want the highlighting to end, just add a “/” before “ins”.
<ins>Hello World!</ins> =
A similar thing happens with highlighting things in red.
<del>Hello World!</del> =
Thanks, I assumed so since the “EDIT” wasn’t highlighted. Good to know!
Thanks for this neat little thing @MetaNinja!
