Quick update: WCIU now allows sorting, and by default displays the most supported features first. Helpful to see which features can be used first.
I’ve added a search box for the “When can I use…” browser support tables. Just start typing a word like “corner”, “SVG”, or “attribute” and only the matched tables will appear.
Other minor updates include the addition of HTML5’s contenteditable (to throw IE a bone) and more unofficial features by Webkit, including CSS Transforms, CSS 3D Transforms, CSS Transitions, CSS Animation, CSS Gradients, CSS Canvas Drawings, CSS Reflections and CSS Masks. I’d be happy to add more non-Webkit features, but other browsers seem to prefer to keep their experimental features apart from their official builds.
This post explains my method used to convert comic book PDFs to CBZ files (CBZ is like CBR but uses ZIPs instead of RARs), for use in ComicZeal or other comic book reading software.
