Naming Web Page Files
Web servers search for default page names Default page names include:
index.html index.htm
Names determined by the serverDesigners must know what type of server hosts the
web pages Apache Server (Linux) -- usually index.html IIS (Windows) – usually index.htm or default.htm
http://www.chromezebra.comThe browser will open the index file without having to type it.
Markup Languages
Extensible HTML (XHTML)Latest formulation of HTMLDefines content rather than format Used to organize data on the pageMore flexible than HTMLUsed to insure accessibility for persons with limited
vision, hearing, etc.Works with Cascading Style Sheets
Web Page Access
Viewing PagesThe page and all referenced images and objects must
reside on a Web server that provides access to the Internet.
File Transfer Protocol (FTP)This is a program that uploads web pages to the web
server. (you will do this in this class)
Options for a server: Contract with an Internet Service Providers (ISP)Set up your own server and Internet access
NOTE: your web page will reside on a server but you will not need a server in this class.
