I'm using placeholders for text inputs which is working out just fine. But I'd like to use a placeholder for my selectboxes as well. Ofcourse I can just use this code:

<select>
    <option value="">Select your option</option>
    <option value="hurr">Durr</option>
</select>

But the 'Select your option' is in black instead of lightgrey. So my solution could possibly be CSS-based. jQuery is fine too.

This only makes the option grey in the dropdown (so after clicking the arrow):

option:first {
    color: #999;
}

Edit: The question is: how do people create placeholders in selectboxes? But it has already been answered, cheers.

And using this results in the selected value always being grey (even after selecting a real option):

select {
    color:#999;
}

How about a non CSS - no javascript/jQuery answer?

<select>
    <option value="" disabled selected>Select your option</option>
    <option value="hurr">Durr</option>
</select>
