How to get width of a div in percentage using jQuery? [duplicate]

Answer 1

you will need to get viewport width and then calculate your element width percentage in accordance with viewport width.

var width = $('#someElt').width();
var parentWidth = $('#someElt').offsetParent().width(); // this will return parent element's width which also can be replaced with docuent to get viewport width
var percent = 100*width/parentWidth;
