• The DOM isn't the only area in which things have gotten better: HTML and CSS are also much more uniform than once they were
• In CSS, there are ways to hide advanced CSS from older browsers
  • @import
  • The media attribute
  • Attribute and other CSS2 selectors
  • The "box model hack"
  • Caio's comment hack
