- The feed selection menu (a narrow rectangle in the upper left)
- The feed items (a large, verticle rectangle in the lower left)
- The main page (where the page will load when the headline is selected)
The three frames of the one page are obviously three HTML documents, but only one of them is real when the page is loaded: the menu. The rest are taken by a blank, filler page. So, we have two pages to construct: index and menu . If this application is to exist on a server on the internet, validation is a must. Let us therefore begin with the DOCTYPE declaration:
This will tell the server which Document Type Definiton (DTD) file to use. The DTD effectively determines the lense through which the server looks at the HTML or XHTML.
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN" "http://www.w3.org/TR/html4/frameset.dtd">
