Site looks cool. Good to see you've made it interactive.

Seems like you are supporting JS flavor, that should be mentioned prominently.

Suggestions for the cheatsheet:

1) Multiline example regex is missing the anchors

2) Negative lookbehind should be `(?<!)` not `(?!)`

3) `+` and `*` examples are using `()` around a character, which isn't needed (the `?` example doesn't use it)
