What is frame? Write its types.?
HTML Frames can be used to split a web page so you can load multiple HTML files or pages into one web page. This will cause the web browser to display multiple pages at one time. A common example of this technique which I like to use is to display an index of a document on the left side of the browser window with descriptions and links so when the reader clicks on the link, that page is displayed on the right side of the browser window. Using HTML frames may be a bit complicated at first for those new to HTML, so you may want to skip this section or skim it, then come back to it when you want to create frames in your HTML documents.
