Radio Button Based Star Rating System

A plain HTML/CSS based rating system that uses SVG stars for rating symbols. Comes with a smooth select / deselect effect based on CSS3 transitions.

How to use it:

Create radio buttons for the 5 star rating system.

<input type="radio" name="stars" id="star-null">
<input type="radio" name="stars" id="star-1">
<input type="radio" name="stars" id="star-2">
<input type="radio" name="stars" id="star-3" checked>
<input type="radio" name="stars" id="star-4">
<input type="radio" name="stars" id="star-5">

Wrap the SVG stars into label elements as follow:

<label for="star-1">
 <svg width="255" height="240" viewBox="0 0 51 48">
 <path d="m25,1 6,17h18l-14,11 5,17-15-10-15,10 5-17-14-11h18z"/>
 </svg> 
</label>
<label for="star-2">
 <svg width="255" height="240" viewBox="0 0 51 48">
 <path d="m25,1 6,17h18l-14,11 5,17-15-10-15,10 5-17-14-11h18z"/>
 </svg> 
</label>
<label for="star-3">
 <svg width="255" height="240" viewBox="0 0 51 48">
 <path d="m25,1 6,17h18l-14,11 5,17-15-10-15,10 5-17-14-11h18z"/>
 </svg> 
</label>
<label for="star-4">
 <svg width="255" height="240" viewBox="0 0 51 48">
 <path d="m25,1 6,17h18l-14,11 5,17-15-10-15,10 5-17-14-11h18z"/>
 </svg> 
</label>
<label for="star-5"> 
 <svg width="255" height="240" viewBox="0 0 51 48">
 <path d="m25,1 6,17h18l-14,11 5,17-15-10-15,10 5-17-14-11h18z"/>
 </svg> 
</label>
<label for="star-null"> Clear </label>
