Eclipse Warnings Invalid location tag on valid HTM

Question

I'm getting Invalid location tag Warning on some tags with Eclipse Neon.3. For example:

<a ...><h1></h1></a>

is valid on HTML5 but eclipse showing Invalid location tag warning for <H1>.

I've seen another question on Why does Eclipse creates warning on HTML script tag?. I don't know it's the same problem as this or not (that question is implying to the Undefined attribute name Warning). but asked on +6 years ago.

Another old Question (+5 years ago) with about the same problem: error on eclipse Invalid location of tag (b). But it's not about how eclipse throw warning for valid HTML5 tags.

How can I fix this warning?

Answer 1

The stupid Eclipse does not fit HTML 5 syntax, although it's already at least 5 years after HTML 5 standard release out. The only way you can do is to force Eclipse "ignore" these warnings. See this post.
