iframe and frame are two commonly used tags in web pages. They can be used to embed another web page in a web page or display other content. Although their functions are similar, there are some differences in practical applications.

1. iframe is a tag in HTML5, and frame is a tag in HTML4. HTML5 is the latest HTML standard. Compared with HTML4, HTML5 provides more functions and better compatibility. Therefore, iframes are more common in modern web development, while frames still exist in some old web pages.

2. iframe is an independent HTML document that can be embedded in another web page. By using the iframe tag, we can display the content of other web pages in a web page without affecting the layout and style of the main web page. The iframe can specify the width and height, can be positioned anywhere on the web page, and can also control whether to display scroll bars by setting attributes. In addition, iframe can also be used to implement block loading of web pages, which can improve the loading speed and user experience of web pages.

frame is a divided area of ​​an HTML document. It can divide a web page into multiple areas and display different web pages in each area. By using the frame tag, we can divide a web page into multiple frames, and each frame can load different web pages. Each frame has its own URL and independent browser window. You can control the size, borders, scroll bars, etc. of the frame by setting properties. However, the frame tag is no longer recommended in modern web development because it has some problems, such as search engine indexing and link processing.

For example, iframe can control whether users are allowed to interact by setting attributes, and multimedia content such as audio and video can be embedded in iframe, while frame does not have these functions. In addition, iframe can control whether to allow cross-domain loading of web pages by setting attributes, while frame does not have this function.

In general, iframe and frame are commonly used tags in web pages. They can be used to embed another web page in a web page or display other content. Although their functions are similar, there are some differences in practical applications. In modern web development, we prefer to use iframe tags because it has more functions and better compatibility. The frame tag is no longer recommended because it has some problems.
