automatically detect web browser window width change?

Question

i know that you with $(window).width() can get the size of the web browser.

i want to detect when the user change the size of his web browser so i could readjust the col

Answer 1

In MDN they give a really good Javascript standalone code:

window.onresize = resize;

function resize()
{
 alert("resize event detected!");
}

If you need just this kind of functionality I would recommend to go for it.
