iframe (Inline Frame) is an HTML tag used to embed other web pages or documents in a web page. It allows embedding a web page into another web page, creating an inline frame, so that multiple web content can be displayed simultaneously in one web page.

Iframes come in many forms. Here are some common forms:

1. Embedding other web pages: The most common usage is to embed a web page into another web page. By using the iframe tag, content from other web pages can be displayed within the current web page. This form is often used to display external content such as ads, maps, videos, etc. For example, a YouTube video can be embedded in a news web page so that users can watch the video directly on the web page.

2. Embed local files: In addition to embedding other web pages, iframe can also be used to embed local files, such as documents, pictures, etc. By specifying a file path, you can display the contents of a local file in a web page. This form is often used to display documents, image collections, or other media files. For example, a PDF document can be embedded in a web page so that users can view the document content directly on the web page.

3. Create an inline window: In addition to embedding other web pages or files, iframe can also be used to create an inline window. By setting the width and height of the iframe, you can create an independent window in the current web page to display other web pages or content. This form is often used to create pop-up windows, dialog boxes or carousels, etc. For example, you can create a carousel to display multiple images on a web page.

4. Implement web page segmentation: In addition to embedding other content, iframe can also be used to achieve web page segmentation. By creating multiple iframes, a web page can be divided into multiple independent areas, each area displaying different content. This form is often used to create multi-window applications or multi-column layouts. For example, a web page can be divided into two areas, with the navigation menu on the left and the content on the right.
