# 8. HTML Input Types Explained: From Text to Passwords

### Introduction

HTML forms are the primary way users interact with websites, whether logging in, signing up, or filling out a survey. This article explores various HTML input types, their purposes, and how they enhance user interaction.

### Understanding HTML Forms

A form in HTML is a container for collecting user input and sending it to the server. Forms consist of:

* **Form Element (**`<form>`): Defines the form and its action.
    
* **Input Elements (**`<input>`): Collect user data.
    
* **Buttons (**`<button>`): Submit or reset the form.
    

#### Example of a Simple Form:

```xml
<form action="/submit" method="post">
  <label for="username">Username:</label>
  <input type="text" id="username" name="username">
  <label for="password">Password:</label>
  <input type="password" id="password" name="password">
  <button type="submit">Login</button>
</form>
```
