To specify the value of a checkbox using an attribute in HTML, you utilize the “value” attribute within the <input> tag. This attribute allows you to assign a specific value to the checkbox, which is sent to the server if the checkbox is checked when the form is submitted.
Syntax
<input type="checkbox" name="checkbox_name" value="checkbox_value">
The table below illustrates the attributes alongside their descriptions.

- Assigning Values: The “value” attribute assigns a specific value to the checkbox, which is submitted to the server if the checkbox is checked.
- Form Submission: When the form containing the checkbox is submitted, the checkbox value is included in the form data sent to the server.
- Identifying Checkboxes: The “name” attribute identifies the checkbox within the form, allowing you to distinguish it from other form elements.
- Multiple Checkboxes: You can have multiple checkboxes with the same name but different values, allowing users to select multiple options.
- Conditional Processing: Server-side scripts can process form submissions based on the values of checkboxes, enabling conditional logic and actions.
