Answer 1

you should not use $("#startegy-sections-targeting-exclude").css('line-height'); if you haven't specified a line-height. in javascript you can use this :

var element = document.getElementById('startegy-sections-targeting-exclude');
var lineheight = document.defaultView.getComputedStyle(element, null).getPropertyValue("lineHeight");
