Overview

In the past tables were used to do much of the layout on a web page, however, using the Div tag in association with Cascading Style Sheets (CSS) is becoming the accepted way to layout a web page. Web page authoring tools such as Microsoft's Expression Web and Adobe's Dreamweaver provide templates you can use to simplify this task.

Center column layout

  • For the body:
    • It is good practice to zero the margin and padding to allow for different browser defaults
    • Text-align: center will center the container in IE5+ browsers
  • For the container:
    • Text-align: Left will override the body center setting
