User:ThreeQC/Template:OK RB Text Block
OKLab Rainbow Text!
Usage
[edit]Like User:ThreeQC/Template:OK RB Text, but in a div instead of a span. Unlike that one, it works for multi-line text (the gradient isn't aware of the line breaks in the other one), but it has to be in its own block. I'm no webdev wizard, so I don't know how (or if) you could get the best of both worlds.
