HTML checked Attribute

The HTML "checked" attribute is a "boolean" attribute and specifies that an <input> element must be checked when the page loads.

You can use this attribute only on the <input> element (<input type="checkbox"> and <input type="radio">).

It is also possible to set the "checked" attribute after the page loads, with JavaScript.


<input type="checkbox|radio" checked>

Example of the HTML "checked" attribute:

<!DOCTYPE html>
    <title>Title of the document</title>
    <h2>HTML Form Example</h2>
    <form action="#">
      <input type="radio" name="game" value="football" checked> Football
      <input type="radio" name="game" value="basketball"> Basketball
