Alexander said: If I am correct its a background image embedded in the roll20 page source. Correct. Is there a way to remove the gray space (see screenshot) and have it black. Yup, you can accomplish this by customizing the in-game CSS with the help of a third-party browser extension (e.g. Stylish): @-moz-document url-prefix("<a href="https://app.roll20.net/editor/" rel="nofollow">https://app.roll20.net/editor/</a>"), url-prefix("<a href="https://app.roll20dev.net/editor/" rel="nofollow">https://app.roll20dev.net/editor/</a>") {
body {
background-color: #000;
background-image: none;
}
} After installing Stylish for Firefox or Chrome , save the code above as a New Style.
