How this tag is working?

Checkout my code. In this code, you'll see that I've written "Hello" between <zxcvbnm> tag and changed it background-color. But in HTML, there is no tag such as <zxcvbnm>. Then how is it working?

It worked because you described it in CSS...that means HTML5 may have treated it like a tag name for use in CSS

Dipro Biswas Anshu Khanra HTML is XML based language so as you can define any tag as you want in XML you can do the same in HTML.
HTML is a simple particular XML convention.

Answer 8

If you define your own tags all will run very well, your web page will be rendered but your web page will not be recognised as a correct web page on the web because it don't match the HTML convention.
XML is used to format documents
and HTML is XML specialised in web documents formating.

DOM architecture.
HTML DOM generated from utf8 text file might not support it. And it might not be supported by JavaScript to update tag attribute and property.
