Hi Kefrem, what sheet do you want to make adjustments to? Unless it's an official sheet by roll20, you can find a copy of the code for a given sheet on roll20's character sheet repository on github . You'll probably only need to edit the text found in the html file, but you'll need the html, css, and translation(if included) when running a custom sheet. Make your edits using a text editor like notepad++. Copy/paste to your custom game using the game settings page. There are three separate tabs (html, css, translation) where you can paste/edit the code. Save and load your game in another tab to test your changes.
