Tables

• rows (tr)

Divs and layout

• We use style and classes to control their appearance

CSS (Cascading Style Sheets)

• Style can be in-line coded (style="")
• Style can be added to a style/endstyle block in the header

HTML ignores most white space

•   must be used to create a dependable space
• Other character entities include © &usd; • ¥

Javascript

• Code typically resides in a script/endscript block in the head section
• href="javascript:history.back()" can be used as a substitute for a real filename

  2. We can create new tags using a Document Type Definition

HTTP

• Hyper text transfer protocol
• Default socket connectivity uses port 80 on the server
• Multiple documents can be sent over a single connection using HTTP 1.1

Index pages

• index.html is the default page for a folder on the community server
• Some servers use default.htm, index.cfm, index.cgi, or perhaps index.htm
• You can also use index.php

File and Suffix conventions

• 3-letter suffixes are good, for example: .gif, .jpg, .wav, .mp3, .html (doh!)
• file names should not have spaces, ' ` ! & $ %
• myfile.gif myFile.gif my_file.gif myFile1.gif my-file.gif
