Spell / grammar checker that can not flag HTML?

Can anyone find me an editor that can disciminate between HTML code and the main text.

my current spell checker/ grammar checker flags all HTML Code as an error.

and when everything is an error, it seems nothing is. You’re so used to skipping HTML that you ignore real errors.

Any good free spell/grammar checkers that at least knows to segregate HTML code as code and not flag it as a misspell? I want to correct, copy and paste quickly
