HTML frames are used to divide a web browser window into multiple sections where each section can load a separate HTML document. Frames are created using the <frameset> tag, which is a container tag for all other tags that are used to create frames). The <frameset> tag replaces the <body> tag in frameset documents). Each frameset defines a set of rows or columns, and if the user defines frames using the rows attribute, then horizontal frames are created. If the user defines frames using cols, then vertical frames are created). The <frame> tag is used to create frames for the content of the web page, and the src attribute is used to identify the resource that should be loaded inside each frame.
Its important to note that frames have been deprecated and should no longer be used in modern web development. The HTML5 standard does not support framesets, and concern for usability and accessibility has motivated diminished use of framesets. Instead of using frames, web developers should use CSS to create a specific look and layout.
