Hi Marc! The first thing I would try after pasting styled HTML (about the only kind you are going to find online), try the format eraser button in the handout's text editor controls. Depending on how it was styled, that might work. It doesn't recognize custom classes that your source HTML might be using, just, H1, H2, blockquote, etc. Otherwise, you would have to have a source of "simple HTML". Unless you are creating it yourself with something like Dreamweaver, that's kind of hard to find. Most online sites have some level of styling, or use things like divs and spans. The most certain results are achieved with the laborious process of pasting plain text and using the internal styling controls. Same with markdown. You can paste markdown into a place that formats and renders it as HTML, but you would have to find a place that guarantees that they are letting the browser decide what font to use, what H1 looks like, etc. Unless you can find sources like that, you have two options that avoid manual styling: Check out Stephen S.' Markdown script. You type or paste markdown in the GMNotes, it references a CSS style handout and renders the HTML in the notes area. If you defined all of your styles like "H1 {}", etc, I'm guessing it would render all basic HTML tags free of extra styling. A script could be written that would strip all styling and non Roll20-handled tags from a handout's HTML. The Format Eraser button does this, but it's not perfect.
