Issue
I'd like to use the CSS border attribute to make a fine 1px grid between span elements, like so.

This is what I currently have. It doesn't quite work obviously.
<html>
<head>
<style>
div {
width: 204px;
}
span {
display: inline-block;
height: 100px;
width: 100px;
border: 1px solid #ccc;
border-left-width: 0;
border-top-width: 0;
}
</style>
</head>
<body>
<div><span>1</span><span>2</span><span>3</span><span>4</span></div>
</body>
</html>
When the div is set to 306px and the elements reflow, the solution should adapt dynamically.

Preferably CSS only, or pure Javascript. Older browsers like IE7 can be ignored.
Solution
I'm using this solution, which automatically sets the border.
HTML
<div><span>1</span><span>2</span><span>3</span><span>4</span></div>
CSS
div {
width: 204px; /* adjust to get less/more columns */
}
span {
display: inline-block;
height: 100px;
width: 100px;
border: 1px solid #ccc;
border-left-width: 0;
border-top-width: 0;
}
JavaScript
var a = document.querySelector('div');
// columns
var b = parseInt(a.offsetWidth / (100 + 2), 10);
for(var c, d = document.querySelectorAll('span'), e = d.length, i = 0; c = d[i]; i++) {
// column
c.style.borderRightWidth = ((i + 1) % b) != 0 ? "1px" : "0";
// row
c.style.borderBottomWidth = parseInt(i / b, 10) * b < e - b ? "1px" : "0";
}
