HTML input
The HTML <input> elements allows you to create interactivity in your website, where users can communicate with you, using forms. Input can be of any type, such as text, file, date, color, etc. Input comes with a special type, that allows you to write your “passwords” but they are hidden behind the asterisks (*). You can have your input form to have a file input, so users can also send you a file. You can also attach images using input.

15. Radio
Unlike checkbox, radio types only allows you to select a single value from a given list of value. For example, if you want to get gender from a user, you can use radio types, since a user can only have a single gender.
<fieldset>
<legend>Select your gender </legend>
<div>
<input type="radio" id="male" name="gender" value="male"
checked>
<label for="male">Male</label>
</div>
<div>
<input type="radio" id="female" name="gender" value="female">
<label for="female">Female</label>
</div>
</fieldset>It should be noted that the name property for both of these radio inputs is same, because they are related and we only need a single value.
If we use different names for both of these inputs, we would then be able to select both the values, which we do not want.
