It does with varying degrees of compatibility.
Note that it usually depends on the operating system, and NOT the version of filemaker that is running that determines compatibility.
Make a simple test and test for yourself before putting in all of the work. The simpler your code, the more compatible it will be.
Just point your webviewer to HTML5test - How well does your browser support HTML5?
and see if it works wherever you want to use it.
Thank you very much. Ran the HTML5 test and see that the renderer is IE 11.
Thank you for this. As you can tell Web is not my first language. I ran the HTML5 test - useful site - and see that I'm running IE 11 thru the WebViewer and that I have a "score" of 471 out of 555 which I guess is OK. The problem I have is with table borders not displaying properly and as I'm not sure which of the HTML elements deals with this, I have some more learning to do. Very much appreciate your taking the time to respond. Very helpful.
CSS is the way to deal with borders and other formatting with HTML5. While you can add 'style' attributes to elements, a separate list of all styles (external or embedded) is preferable.
