In this HTML tutorial, we will explore the usage of radio buttons and checkboxes. Radio buttons and checkboxes are essential form elements that allow users to make selections and express preferences. We’ll delve into the structure of these elements, their attributes, provide code examples, and conclude with key takeaways.
Introduction to Radio Buttons and Checkboxes
Radio buttons and checkboxes are essential form elements used to collect user preferences, make selections, and perform various tasks within web applications. Understanding how to create and customize radio buttons and checkboxes is vital for web developers.
Radio Buttons
Radio buttons are used when users need to make a single selection from a list of options. They allow users to choose only one option from a set of mutually exclusive choices. Each radio button is associated with a specific value.
Checkboxes
Checkboxes, on the other hand, allow users to make multiple selections from a list of options. Users can select one or more checkboxes simultaneously, making them suitable for tasks where multiple choices are allowed.
The <input> Element
Both radio buttons and checkboxes are created using the <input> element with specific type attributes.
Here’s a basic example of radio buttons and checkboxes:
|
1 2 3 4 5 6 7 8 9 10 11 12 |
<label> <input type="radio" name="gender" value="male"> Male </label> <label> <input type="radio" name="gender" value="female"> Female </label> <label> <input type="checkbox" name="interest" value="sports"> Sports </label> <label> <input type="checkbox" name="interest" value="music"> Music </label> |
type: Specifies the type of input element, which isradiofor radio buttons andcheckboxfor checkboxes.name: Assigns a name to the input element to group related options.value: Specifies the value associated with the selected option.
Code Examples
Here are examples of radio buttons and checkboxes with different attributes and options:
Radio Buttons:

Conclusion
Radio buttons and checkboxes are fundamental for creating interactive forms and collecting user preferences. Understanding how to create and customize these elements using the <input> element and its attributes is essential for web development. Whether you’re building a survey, a preference selection form, or any other feature that requires user choices, radio buttons and checkboxes play a pivotal role.
When using radio buttons, remember that users can only select one option from a list of mutually exclusive choices. Checkboxes, on the other hand, allow multiple selections. Ensure that your forms are designed for usability and accessibility, and implement validation to process user choices effectively.
