Working with radio buttons

To create a radio button, use the following HTML tag:

<input type="radio" name="name" value="value" />

where name identifies the field containing the radio button and value attribute specifies the value sent to the CGI script.

To make a particular radio button a default option, use the attribute checked="checked":

<input type="radio" name="name" value="value" checked="checked" />

The radio buttons are used whenever the input options are mutually excluding.
