HTML - Checked


checked is an HTML attribute that indicates via its value (true or false - default to true) if the form control element is checked.


It's used:

<input type="checkbox"  name="indicator" checked/>
<input type="radio" name="choice" value="regular" >
<input type="radio" name="choice" value="deep" checked >

That in a select select option, the same functional attribute is called selected

  <option value="blue">Blue</option>
  <option selected value="green">Green</option>


The checked state is also available in css via the pseudo class :checked (available also for the selected option of a select element)

<input type="checkbox"  name="indicator" checked/>
