I use Stylish plugin on Chrome to adjust the CSS styles in my ROLL 20 games to help with vision and color blind condition. I began using it to increase the size of the fonts in the modules I was using and also enhance block quotes for call-out text. Then it started becoming more useful when I realized I could not see the color of the text in crit and fumble rolls. The simple CSS below creates a background color to show the crits and fumbles more clearly. I hope this helps others. .inlinerollresult.showtip.tipsy-n-right.fullcrit { background-color: #336600; color: yellow; padding: 5px; line-height: 2; } .inlinerollresult.showtip.tipsy-n-right.fullfail { background-color: #ff0000; color: #ffffff; padding: 5px; line-height: 2; }
