Supported CSS Styles

Attention! MapTool 1.6+ contains [frame5():] and [dialog5():] roll options, which support modern HTML 5, CSS, and JavaScript.
MapTool 1.7+ additionally contains an [overlay():] roll option which allows HTML 5, CSS, and JavaScript user interfaces directly in the map view, and adds access to several Whitelisted CDNs for easy inclusion of Bootstrap CSS, Google Fonts, and JS libraries such as jQuery.

MapTool supports a subset of the CSS level 1 specification in the chat panel, and in the panels created by [frame():] and [dialog():]. These styles can be used in-line, and also as external styles within dialogs and frames. This is not meant to be an exhaustive reference, nor an introduction to CSS, this page is only a collection of which properties are supported and to what extent. If you are looking for an introduction to CSS, visit W3Schools CSS Tutorial

Also, note that some CSS attributes are modeled but not rendered, meaning that they can be used and will be recognized, they just won't have any effect on the rendered result. The list is available straight from the Java documentation: CSS Styles
