I have a textarea in my HTML. I need to get the padding numerical value in pixels as either integer or float. How can I get it using JavaScript? I am not using jQuery, so I'm looking for pure JavaScript solutions.
This will return the padding-left value:
window.getComputedStyle(txt, null).getPropertyValue('padding-left')
where txt is the reference to your TEXTAREA element.
The above works in all modern browsers and in IE9. However, it does not work in IE8 and below.

Btw, just for comparison, this is how you get the same job done using jQuery:
$(txt).css('padding-left')
The above does work in IE6-8.
