In this article, we will explore HTML <input> and its various types, as well as how to use it to create forms and collect data from users.

What is the <input> Element in HTML?

The <input> element is an HTML element used to gather information from users through various types of input such as text, numbers, choices, and more. This element is one of many form elements used to collect data from users, which can then be used for various purposes, such as registration, searching, or other interactions.

There are several types of <input> elements in HTML, each suitable for different input types. Here are some common types of <input> elements:

1. <input type="text">

This element is used to collect text input from users. Typically, it is used to collect names, email addresses, or other text information.

Example usage:

<label for="name">Name:</label>
<input type="text" id="name" name="name">

2. <input type="password">

This element is used to collect passwords from users. The entered input is usually obscured with asterisks or dots for security.
