. said: Hi, Can i ask for a Prophecy sheet (ex: here ) what is needed to do a sheet ? Lots, and a little. You will need to submit the html and css files to Github, and it would need to be approved by the devs (a process that, I believe, involves a magic eight ball, a few seers, and a conversation with the Old Ones), and then both the Github and Roll20 websites need to update. While you can make any sheet using notepad or other basic html editor, a lot of people use the 'custom' sheet option so they can see how Roll20 uses the code directly. Its also color coded, and has a few bells and whistles that are neat. There is a thread...somewhere in this forum, where all kinds of folks talk about what programs they use to edit the sheet. Personally, I use the custom sheet and Notepad++. Copy, paste, and Find/Replace are good friends of mine. They treat me well. Basic understanding of html is a huge bonus, but I started with next to no understanding and a lot of determination. The "Headbutt-Things-Into-Submission" isn't the most efficient method of learning, but it works for me. The CSS Wizardry thread is a gold mine of awesome. All kinds of very cool things exist there to help make almost any sheet better.
