I'm attempting a gray drop-shadow effect on a note in post #1072996, but the only coding I can find to create the effect is CSS-based rather than HTML-based, and it gets stripped/sanitized when I save the note, even though the effect shows up in the Greasemonkey-based preview. Does a way to create this effect within Danbooru's current note coding parameters exist, or should I just not worry about it?
Pardon if this is already covered in another thread; my attempts at key word searches didn't uncover anything that already answers the question. Feel free to answer with a relevant link if I've managed to overlook the appropriate thread.
