Is it possible to adapt font size to div width with CSS?

Question

I have a div with 70% width, and here’s what I want to do:

• Put some words in that div
• Adapt font size so that those words occupy all div

Answer 1

Yes but I think you need to use JS(jQuery).

JS:

$(function(){

var box = $('.box');
var boxWith = box.width();

$('.box h1').css('font-size',boxWith);

});
