Note that "z-index" includes all aspects of the CSS stacking algorithm. Also note that it's possible for rendering objects to become "accidentally" invisible as a result of other things stacking on top of them, just like it can happen with colors. Oh, "visibility:collapse" on an ancestor may affect rendering object visibility even if the rendering object has some other visibility setting. I'm not sure whether you care about the difference between: <div style="opacity: 0">Text</div> and <div style="color: rgba(255, 255, 255, 0);">Text</div> Is the latter "color-related"? -Boris _______________________________________________ dev-embedding mailing list [email protected] https://lists.mozilla.org/listinfo/dev-embedding
