These are the demo files to go along with the tutorial.
A plain HTML document with default styling. A 22px baseline grid shows that text has a poor rhythm.
The same document with CSS making text flow with the baseline grid.
The same document with the same CSS, but now with images included. Notice how text starts to become mis-aligned.
A partial solution which confirms the principle is sound, but has some implementation quirks.
A document that keeps a clean vertical rhythm throughout and deals with re-scaled images in liquid layouts.
