How to create radio button in an HTML page

HTML Radio Button in a Form

In HTML, a radio button is used to allow users to make a single selection from a list of options.

Radio buttons are used in groups, where each button represents a different choice option. Users can select only one option at a time within the group.

How to Create a Group of Radio Buttons

Create an HTML <input> element inside an HTML form element.

Add type="radio" (type attribute with value 'radio') to the <input> element. Type attribute value is set to 'radio' to define the input element as a Radio button.

Add name="program" (name attribute with value 'program') to the <input> element.

The name attribute (program) will link all radio buttons together into a group.

Add value="Python" (value attribute with value 'Python') to the <input> element. The value attribute here sets the option value of the radio button.

Add a label ( <label>Python</label> ) next to the radio button to display the text "Python" next to the radio button.

Add two more radio buttons following the above instructions with value="Java" and value="C#" and add two labels with text "Java" and "C#".
