jQuery(window).height inaccurate

Question

I\'m doing a simple test on $(window).height() and I\'m getting a value of 2602 on a screen resolution of 1366 x 768.

jQuery(document).ready(function($){

           


        

Answer 1

This can be just as simple as a missing or incorrect DOCTYPE (affected Chrome but not IE).

Interestingly this isn't even a jQuery issue - it affects document.documentElement.clientHeight too.

Without doctype:

With doctype:

I thought I had a layout template on my page, but it turned out I didn't - and therefore didn't have DOCTYPE.
