An HTML iframe, which stands for “inline frame,” is an HTML element that allows you to embed another document within the current HTML document. This embedded document can be of various types, such as another web page, a video, a map, or any other content that can be displayed in a browser. Iframes create a window or frame on your web page where the embedded content is displayed.
In the below PDF we discuss about HTML Iframes in detail in simple language, Hope this will help in better understanding.
Basic Structure of an Iframe:
To create an iframe, you’ll need to use the <iframe> tag in your HTML. Here’s a basic structure of an iframe:
<iframe src="URL_to_embedded_content" width="width" height="height" title="Description"></iframe>
Let’s break down the essential attributes:
- src: This attribute specifies the URL of the content you want to embed within the iframe. It’s the most critical attribute, as it determines what gets displayed in the iframe.
- width: You can set the width of the iframe using this attribute. It can be defined in pixels, percentage, or other units.
- height: This attribute controls the height of the iframe and can also be defined using various units.
- title: The title attribute is crucial for accessibility and SEO. It provides a description of the content within the iframe.
How to Use Iframes:
Now that you understand the basic structure of an iframe, let’s look at some common use cases and how to implement them.
1. Embedding a Webpage:
To embed an external webpage within your own, simply set the src attribute to the URL of the webpage you want to embed. For example:
<iframe src="https://www.example.com" width="800" height="600" title="Example Website"></iframe>
This code will display the “example.com” webpage within an 800×600 pixel iframe on your page.
2. Embedding Videos:
Iframes are often used to embed videos from platforms like YouTube or Vimeo. You can do this by setting the src attribute to the video’s URL.
<iframe src="https://www.youtube.com/embed/video_id" width="560" height="315" title="Video Title"></iframe>
This code will embed a YouTube video with the specified dimensions.
3. Creating a Google Map:
Iframes are also handy for embedding maps. To embed a Google Map, use the embed code provided by Google Maps and place it in the src attribute.
<iframe src="https://www.google.com/maps/embed?parameters" width="600" height="450" title="Location Map"></iframe>
An HTML iframe (short for inline frame) is an HTML element that allows you to embed another web page or content within the current web page. It creates a window or frame within the page to display external content.
You can create an iframe using the <iframe> element. You specify the source URL of the content to be displayed within the iframe using the src attribute.
The src attribute in an iframe specifies the source URL of the web page or content that should be displayed within the iframe.
If the src URL in an iframe is invalid or does not exist, the iframe will display an empty frame, or it may show a default error message depending on the browser.
To make an iframe responsive, you can use CSS to set the width of the iframe to a percentage value and use the aspect-ratio property, which helps maintain the correct aspect ratio as the screen size changes.
