Radiobutton list in HTML

Introduction:

A radiobutton list is a type of form element used in HTML to provide users with multiple options to choose from. It allows users to select only one option at a time. Radiobutton lists are commonly used in online surveys, quizzes, and registration forms where users need to make a single choice from a given set of options. In this article, we will discuss the usage, implementation, and customization of radiobutton lists in HTML.

Usage:

Radiobutton lists are created using the `` element in HTML. Each radiobutton element should have a unique `name` attribute and a corresponding `value` attribute. The `name` attribute is used to group the radiobuttons together, while the `value` attribute defines the value associated with the radiobutton. Only one radiobutton within the same group can be selected at a time.

Implementation:

To create a radiobutton list, you can use the `` element inside a `

` element. Here's an example:

<form> <input type=\"radio\" name=\"color\" value=\"red\"> Red <input type=\"radio\" name=\"color\" value=\"blue\"> Blue <input type=\"radio\" name=\"color\" value=\"green\"> Green </form>

In the example above, we've created a radiobutton list with three options: Red, Blue, and Green. The `name` attribute is set to \"color\" for all three radiobuttons, indicating that they belong to the same group. The `value` attribute is set to the respective colors.

Customization:

Radiobutton lists can be customized using CSS to change their appearance. You can style the radiobuttons using the `input[type=\"radio\"]` selector and apply different styles to the checked and unchecked states. For example:

input[type=\"radio\"] { margin: 5px; } input[type=\"radio\"]:checked { background-color: #FF0000; color: #FFFFFF; }

In the above CSS code, we've set a margin of 5 pixels for all radiobuttons. We've also specified styles for the checked state using the `:checked` pseudo-class. When a radiobutton is selected, it will have a red background color and white text color.

Conclusion:

Radiobutton lists are a useful and intuitive way to present options to users in HTML forms. They allow users to make a single selection from a predefined set of options. By understanding their usage, implementation, and customization through CSS, you can create radiobutton lists that perfectly fit the design and functionality requirements of your web application.

Remember to always test your radiobutton lists across different browsers and devices to ensure consistent behavior and appearance.
