var spans = document.getElementById("chain").getElementsByTagName("span"); for(var a = 0; a < spans.length; a++) { var target = spans[a]; target.innerHTML = a; }

Maybe try and look up for Jquery if you want to do it in Javascript In css you can refer to it as: span { .... } This means you will effect all spans in the document!!

With css selectors, you can target each <span> direct childs of a specific element by: #chain > span:nth-child(n) ... where n is the index (started at 1) of yours spans. '>' operator is required to target only direct childs, else you could select also deeper childs: #chain span:nth-child(2) { color:red; } with: <div id="chain"> <span>I'm not styled</span> <span>I'm red</span> <p> <span>I'm not styled</span> <span>I'm red also as I'm second child of p which is child of #chain</span> </p> </div> You could also use ':first-child', ':last-child' for first and last child, and also look at specificity of ':first-of-type', ':last-of-type', and 'nth-of-type(n)'...
