Prerequisites
- Basic knowledge of HTML
- General understanding of web development

2. Step-by-Step Guide

An iframe (inline frame) is an HTML element that allows you to embed another HTML document within the current HTML document. The iframe tag includes several attributes that you can control to customize the behavior of the embedded content. Some of these attributes include src, height, width, frameborder, scrolling, and allowfullscreen.

## Iframe Basic Syntax
The basic syntax for an iframe is as follows:

```html

```

## Iframe Attributes
- src: Specifies the URL of the page to embed.
- width and height: Define the size of the iframe.
- frameborder: Determines whether to display a border around the iframe (1 = yes, 0 = no).
- scrolling: Controls the appearance of scrollbars (yes, no, auto).
- allowfullscreen: Allows the iframe to be displayed in full-screen mode.

3. Code Examples

Consider the following examples:

### Example 1: Basic Iframe

```html

```

This code will insert a YouTube video into your webpage. The video is defined by the URL in the src attribute.

### Example 2: Iframe with Size Attributes

```html

```

The width and height attributes are used to specify the size of the iframe.

### Example 3: Iframe with Additional Attributes

```html

```

The frameborder="0" attribute removes the border around the iframe, making the embedded content appear more seamlessly integrated with your webpage. The allowfullscreen attribute permits users to view the content in fullscreen mode.

4. Summary
