Cool toy. Nice graphics. Don’t know if it has any other purpose besides being artistic and all that, but it visualizes quite good how ’semantic’ your website in fact is.
What it means:
The brightness of the lines is determined by the importance of the tags in terms of structure.
- H1 is brighter than H2, which is brighter than H3.
- TABLE is brighter than TR, which is brighter than TD tags.
- Images and flash elements appear as 70% white.
- New HTML tags like STRONG and EM is brighter than older ones like B and I
- UL, OL and DL is brighter than their LI, DT, DD
- DIV layout is brighter than table layout
Basically a semantically rich site will appear brighter than one with messy old-style code.
