home page
Your home page is the main page of your web site, the page your site visitors will see when they go to your web address or domain, such as http://www.geocities.com/widgetdesigns or http://www.widgetdesigns.com. The file that generates this default web page (often called the index page) when you create your site with GeoCities is called "index.html." A site visitor can see your home page when he enters either your site's web address (http://www.widgetdesigns.com) or your web address plus /index.html (http://www.widgetdesigns.com/index.html) in the address bar of his web browser.

When you build your own web site or page using a Yahoo! tool, your home page will be named "index.html" automatically. Be sure you do not change the name of this file, or your new home page will not display at your domain. If you create your home page using a third-party tool, be sure to name your main page "index.html." Learn more.
HTML
HTML, or Hypertext Markup Language, is a formatting language used to create web pages and documents. HTML consists of sets of codes (called tags) that are used to control the way a document is displayed by a web browser, such as Netscape Navigator/Communicator or Microsoft Internet Explorer. A document that is formatted using HTML tags — such as the page you're viewing now — is called an HTML document. Learn more about HTML.
