Can I add custom attribute to HTML tag?

Question

Can I add custom attribute to HTML tag like this: `<tag myAttri="myVal" />`

Answer 1

Hi there. The short answer is: yes, you can. However, you shouldn't for some reasons:

1. browsers don't recognize it (although you can still access them via JavaScript)
2. html has the "data" attribute, which exists specifically so that custom attributes can be used. i.e data-myAttr="myVal". Both CSS and JS have access to data attributes.

I hope this helps!
