Is having multiple classes in a single element a good practice? Like so:

<div class ="panel panel-primary panel-hide text-center">

Or is it better to do this:

<div class ="panel">
    <div class="panel-primary">
        <div class="panel-hide">
            <div class="text-center">
             <!-- content here -->

Or is it better to limit classes to 2 or 3 per div?

Or does it even matter?
