The label tag
The default, classless <label> has no special styling, and is commonly used on above or beside form input fields:
<label>Label</label>
The label utility class
Codebase has a UI label class, that you can apply label to a <label>, or a <span>, or other inline element. This will give you:
<label class="label">Label</label>
UI colors
The label class default backgroud is middle gray, same as bg-info. Add a UI background color utility class, and you can have:
Really? Required Winner Anything Author Description Uncaregorized
<span class="label label-warning">Really?</span>
<span class="label label-danger">Required</span>
<span class="label label-success">Winner</span>
<span class="label label-info">Anything</span>
<span class="label label-primary">Author</span>
<span class="label label-secondary">Description</span>
<span class="label label-tertiary">Uncaregorized</span>
Labels can sit comfortably within a block of text, as you can see for yourself. That text can occupy multiple lines, and the label will not disturb the vertical rhythm.
