  • Use CSS and web standards techniques for the coding of content, and the graphical styling and positioning of content.
  • Avoid using table markup for graphical layout, if you do use tables for layout make sure the content still is meaningful when the table markup is disabled.
  • Avoid using nested tables for layout, the deeper the level of nesting the more chance there of having a confusing sequence of content.
  • Tables that are used for layout should use only tr and td elements, and the table, tr and td elements should have a role="none" attribute to clearly indicate the table markup is being used for layout.
