To label a radio button, add a <label> element after the <input> element and insert a for attribute with the same value as the id of the associated <input> element. Then, write your label text in the <label> tag. While using <label> isn't strictly necessary, it's considered a best practice for two reasons.

The radio button is an HTML element that helps to take input from the user. Although it is hard to style the radio button, pseudo-elements makes it easier to style the radio button. Radio buttons are applied when there is the requirement of a single selection from a group of items.

The <input type="radio"> defines a radio button. Radio buttons are normally presented in radio groups (a collection of radio buttons describing a set of related options). Only one radio button in a group can be selected at the same time.

The radio button component is comprised of a set of clickable circles (the inputs) with text labels positioned to the right. If there is a group of radio buttons, a group label can be added. Group label (optional): Describes the group of options or provides guidance for making a selection.

In order to create a radio button, we need to define the input element and assign it to a variable called input. Then, change its input type to radio. Finally, append the input element to the label element.

Radio buttons allow the user to select one option from a set. You should use radio buttons for optional sets that are mutually exclusive if you think that the user needs to see all available options side-by-side. If it's not necessary to show all options side-by-side, use a spinner instead.
