<form action="">
    <input type="text" value="" class="card-num" />
    <input type="text" value="" class="card-cvv2"/>
</form>

<div class="description">
    <p class="card-num">Enter your 16 digit card number</p>
    <p class="card-cvv2">Enter the 3 digit number at the back of your card</p>
</div>

All descriptions are hidden initially. But when hovered on an element that has a matching

tag, display description?

I'd really appreciate any help.

Many thanks!
