HOW TO: Validate a live DOM (live HTML altered by JavaScript)

[Albert Wiersch]

These days HTML is dynamic and often changed by JavaScript. Pages aren't static anymore like in the "good old days" of Web 1.0.

You may be wondering how you can check a web page that has been altered by JavaScript. You can do this by checking the HTML generated from a live DOM.

Here is a page that describes how you can do this using CSS HTML Validator and Chrome:
