I have been trying to find an HTML editor for HTML5 that will flag obsolete tags. Since browsers need to be backwards compatible, editors don't complain if you use
spacer, or other things that are flat out "incorrect" - let alone if you are using an element on an attribute incorrectly.
There are a few sites that will scan a page after you publish it and output the non-HTML5 compliant aspects, but I was hoping to find an editor that would do it real time.
For Windows and ideally free (obviously) though I'd be open to paying if it is not an arm and a leg. Arm OR a leg would probably be OK though.
Sublime or something similar would be ideal in terms of functionality if it also flagged the obsolete/non-compliant aspects.
