Aptana doesn't know about <main> tag in HTML5?
1 answer
If you want to get rid of the error, you can disable the Unrecognized Elements warnings as follows:
Window> Settings> Aptana Studio> Verification> HTML Tidy Validator
Select HTML Tidy Validator> Elements> Unrecognized Elements
Note that without these warnings, you can enter undefined tags (for example, <abc>).
