HTML version 4 vs 5

Question

Is there any way to avoid HTML 5 parser? My application has the following doctype type:

DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd" 

And I want it to be interpreted using HTML4 definitions, not HTML5

EDIT:

My question is to solve this problem: Chrome popup. Fill in this field

Answer 1

New answer based on updated question:

These are not HTML HTML parsing rules that you encounter, they are HTML 5 attribute support. No, you cannot override this. If you do not want to use new things in HTML 5 - do not use them in your document!

Original answer:

No no.

HTML 5 parsing rules are basically "What browsers have been doing for the past decade and a half anyway."

This simply allows us to avoid the excellent SGML features with limited language support (and validators that pass them as valid).

Answer 2

You have nothing to do with HTML 4 and HTML 5 (and not even their parsers). This is due to the fact that you invented your own non-standard attributes (which you should not have done in the first place), and now new standardized attributes (or attributes in the standardization process) collide with them.

Answer 3

Thanks U Everything, but especially thanks to the college who knew how to solve my problem:

You can disable validation on the form.
