<frame>
HTML <frame> Tag
The <frame> tag defines a specific window, a frame, where we can load another web page. Use the src attribute to define the address of this web page. The web page can have several such frames.
The <frame> tag is used with the <frameset> element, which defines how to divide the window into frames.
The <frame> is a deprecated HTML tag and is not supported in HTML5. Use the <iframe> tag instead.
If you want to use frames in a web browser instead of the <body> tag, you can put the <frameset> tag. It defines the structure of a frame (zone in the browser window, where we can load another web page), the number of columns and rows, and also how many percent/pixels it will occupy in a frame. But take into account, that this tag is deprecated in HTML5, too.
The pages that contain frames can be validated only if the is set to HTML Frameset DTD or XHTML Frameset DTD. （>只有当设置为HTML Frameset DTD或XHTML Frameset DTD时，才能验证包含框架的页面。）
Use the rows attribute of the <frame> tag for defining horizontal frames, and the cols attribute for defining vertical frames.
Syntax
Syntax （语法）
The <frame> tag is empty, which means that the closing tag isn’t required. But in XHTML, the (<frame>) tag must be closed (<frame/>).
Example of the HTML <frame> tag:
<!DOCTYPE html>
<html>
<head>
<title>Title of the document</title>
</head>
<frameset cols="50%,50%">
<frame src="https://www.w3cdoc.com/learn-html/html-basic.html">
<frame src="https://www.w3cdoc.com/learn-css/css-syntax.html">
</frameset>
</html>

Frames vs iframes
Frames vs iframes （框架与iframe）
The <frame> and <iframe> elements have similar behaviour. However, there are some differences between them. The <frame> tag is used with the <frameset> element, which defines how to divide the window into frames. Each of these frames has its content. The <iframe> tag inserts the frame directly into the same row with the other elements of the web page.
