xhtml - How to make HTML code inactive with comments

Question

I have some HTML code on a page that I don't want to erase, but make inactive for the short term. How can I make the browser ignore parts of the page in the same way the // works in some programming languages?

Answer 1

Behold HTML comments:

<!-- comment -->

The proper way to delete code without deleting it, of course, is to use version control, which enables you to resurrect old code from the past. Don't get into the habit of accumulating commented-out code in your pages, it's no fun. :)
