Question

How do I retreive the line-height of an element without the “px”?

Using this I get the full line-height value including the px.

$('#example').css('line-height');

Answer 1

Parse it as an integer with parseInt

parseInt($('#example').css('line-height'), 10);

Outputs:

18

As an integer. The other solutions maintain the String type.

EDIT

For values that may contain decimal points, you can use parseFloat()

parseFloat($('#example').css('line-height'));

Outputs:

18.4
