Definition and Usage
A form element may contain both a label for its data value, and the data value itself. For such elements, the ::value pseudo-element selects the representation of just the data value itself, in order to style its appearance.
Syntax
element:value { style properties }
Examples
<input> <label>Zip code<label> <input::value/> </input>
input { border:dashed }
label { border:dotted }
input::value { border:solid }
