HTML Iframe
Through examples, we will learn about HTML iframes and their implementation. In HTML, iframe stands for Inline Frame. The <iframe> element specifies a rectangular zone within the content in which the browser can show a distinct document, complete with scrollbars and borders.
An inline frame is a type of frame that allows another page to be embedded into the current HTML text. The HTML iframe name property specifies a reference for an <iframe> element. In JavaScript, the name attribute is also used to refer to elements. The iframe is mostly used to display a webpage within the current web page.
The src Attribute is used to define the URL of the document that will be shown in the iframe.
Syntax
Attributes value
It has a single value URL, which is the URL of the content included in the iframe. URL links are classified into two categories, which are given below:
- Absolute URL: It directs you to another website.
- Relative URL: It refers to additional files on the same web page as a relative URL.
Height and Width
The height and width properties are used to define the iframe's size. The property values are normally supplied in pixels, but they can alternatively be specified in % such as "80 %".
Getting removing the border
By default, an iframe has a border around it. To remove the border, we must utilize the CSS border property and the style attribute.

FAQs
Yes, an iframe can be styled with CSS. You can target the iframe element itself, as well as the content within the iframe using CSS rules. However, it's important to note that due to security restrictions, you cannot modify the styles of the content within the iframe if it comes from a different domain. Additionally, some styles may not apply to iframes depending on the browser and its version.
To make an iframe responsive, you can use CSS to adjust its dimensions based on the screen size. One way to do this is to set the width of the iframe to 100% and the height to 0. Then, use padding-bottom to set the height based on the aspect ratio of the content being displayed. For example, if the aspect ratio is 16:9, you can use a padding-bottom of 56.25% (9 divided by 16 multiplied by 100). This approach ensures that the iframe will scale proportionally as the screen size changes.
iframes are a powerful tool in HTML for embedding content from other sources into a webpage. However, there are some best practices to keep in mind when using them:
- Use iframes sparingly, as they can slow down page load times.
- Ensure that the content being loaded into the iframe is secure and trustworthy.
- Use the "sandbox" attribute to limit the capabilities of the embedded content and prevent security vulnerabilities.
- Use CSS to style the iframe and its contents, but be aware that cross-domain restrictions apply.
- Make the iframe responsive by setting its width to 100% and using padding-bottom to adjust the height based on the aspect ratio of the content.
