Modifying inlineroll appearance

This is a very basic question, but since I know nothing about CSS, I fear I still have to ask it, please help me out: how do I modify the appearance of inline rolls in sendChat messages I send via the API? E.g. remove the ugly yellow background, but perhaps keep other properties such as bold text and the tooltip.

Do you want this done for just you? If so you can use the browser extension stylish and copy my css: .inlinerollresult { background: 0 0; border: 2px solid rgba(0, 0, 0, 0); border-radius: 3px; } That should cover what you asked for. I use those for rolls within the shaped roll template.

That's nice as far as the style goes, but I want this done for everyone. Can I somehow override what the inlinerollresult style looks like when it's part of my sendChat message?

Nope. You could only modify what appears in a roll template for everyone via editing the sheet. Otherwise you can only do for yourself.

Though if you make the rolls in the API and just send the results to the chat, you can format them however you like. 

Shame :(. I do not want to write my own dice roller, so making the rolls myself is out. Using a sendChat callback would be possible I suppose, but I don't really to write all of that for a bit of formatting.

One small change you can make with ease, you can choose to apply the Green border or the Red border around the yellow box, by using "critical success" and "critical failure" macro codes (cs, cf). This does not remove the yellow highlighting, but it's somethin'. <a href="https://wiki.roll20.net/Dice_Reference#Critical_Su" rel="nofollow">https://wiki.roll20.net/Dice_Reference#Critical_Su</a>...
