    This will come in handy, will use a subtle rgba colour background on selection – cheers :-)

    I ran a test case with this because i was doing this the long way. Come to find out, if you happen to already know the labels for="" and input’s id, then a switch case is quicker.

    $('form :input').bind({
        focus: function () {
            var id = $(this).attr('id').toString();
            var add = $("label[for='" + this.id + "']").addClass('labelfocus');
            switch (id) {
                case 'title':add;break;
                case 'description':add;break;
                case 'resource':add;break;
                case 'tag':add;break;
                case 'theme':add;break;
                case 'language':add;break;
        blur: function () {

    jsPerf Benchmark Test Case (Slightly modified with triggering events). I do however prefer this method due to the less code and easy to use, especially if you have dynamic forms.

    You can style it with just CSS if you put the label after the input

    <input id="something-cool" type="text" />
    <label for="something-cool">Something Cool</label>
    input:focus + label { position: relative; top: -20px; }

Posting Code

We highly encourage you to post problematic HTML/CSS/JavaScript over on CodePen and include the link in your post. It's much easier to see, understand, and help with when you do that.

Markdown is supported, so you can write inline code like `<div>this</div>` or multiline blocks of code in triple backtick fences like this:

  function example() {
    element.innerHTML = "<div>code</div>";
