Add dedicated classes for missing HTML tags #268
Description
I did a comparison between the implemented tags and the HTML tags listed at MDN.
The following lists don't include obsolete tags (e.g. <marquee>), or SVG and MathML elements (e.g. <math>, <svg>).
To find out which tags are implemented and which are not, I searched for the tag name in tests. The table uses three states:
- ✅ — dedicated class with specialised methods
- ✅ (by CustomTag) — no dedicated class, but
CustomTaghas explicit void-element knowledge for it (seeVOID_ELEMENTSinCustomTag.php), so it renders correctly without needing to call->void()manually - ❌ — no dedicated class; can still be produced via
CustomTagbut requires a manual->void()or->normal()call
Should any of the following tags have their own named class? There are a few I consider particularly useful to add: <head>, <main>, <details> + <summary>, <dialog>, <dl> + <dt> + <dd>, <progress>, and <figure> + <figcaption>.
This is intended as a tracking issue rather than a single PR.
HTML Tags
I'd gladly implement any (or all) of the missing tags from this list, ideally one small group at a time.
