Checkboxes and Radio Buttons Tutorial - HTML

Welcome to this HTML tutorial on checkboxes and radio buttons! Checkboxes and radio buttons are essential form elements used to allow users to select one or multiple options from a list. Understanding how to use them is crucial for building interactive and user-friendly web forms.

Creating Checkboxes and Radio Buttons

To create a checkbox, use the <input> element with the type attribute set to "checkbox". Here's an example code for a single checkbox:


    <input type="checkbox" name="option1" id="checkbox1" checked>
    <label for="checkbox1">Option 1</label>

For radio buttons, use the <input> element with the type attribute set to "radio". Only one radio button in a group can be selected. Here's an example code for a group of radio buttons:


    <input type="radio" name="gender" value="male" id="maleRadio">
    <label for="maleRadio">Male</label>
    <input type="radio" name="gender" value="female" id="femaleRadio">
    <label for="femaleRadio">Female</label>

In the code examples, we've used the "name" attribute to group related checkboxes and radio buttons together, and the "for" attribute in the label tag to associate the label with the input element. The "checked" attribute in the checkbox example pre-selects the checkbox by default.

Steps to Create Checkboxes and Radio Buttons

Follow these steps to create checkboxes and radio buttons:

Open your preferred text editor and create a new HTML file.
Inside the <body> tag, add the <input> elements with the appropriate type attribute for checkboxes or radio buttons.
Use the "name" attribute to group related checkboxes and radio buttons.
Optional: Add label tags with the "for" attribute to improve usability.
Save the file with a .html extension and open it in your web browser to see the checkboxes and radio buttons.

Common Mistakes to Avoid

Missing "value" attribute: For checkboxes and radio buttons, it's important to include the "value" attribute to specify the data sent when the form is submitted.
Incorrectly grouped radio buttons: Ensure that radio buttons that belong to the same group have the same "name" attribute.
Using checkboxes for mutually exclusive options: Checkboxes allow multiple selections, while radio buttons are for exclusive choices.
