I'm looking for a short jQuery snippet to count how many divs I can have horizontally in my browser window. Basically, I'm using a fluid layout, like this:

<div id="wrapper">
    <div id="content">
        <div class="foo" />
        <div class="foo" />

Wrapper is 100% width, and foo about 250px wide. What's the simplest way to determine how many there can be in a single row? I prefer flexibility. If wrapper is changed to some fixed width in CSS, it should still work.

Not sure maybe this could work

  var $target = $(event.target);
  if ( $target.is("div").css('display','inline') ) {

Found what I was looking for:

var count = Math.floor($('#wrapper').innerWidth() / $('.foo').outerWidth(true));

The true parameter for outerWidth takes the margin into consideration.
