I would suggest using a rule/guideline based approach that will allow developers to rack up some quick wins with comparatively little effort. 1. Show a horribly crowded page of text. 2. Give them the rule: "For most text use a line-height of about 1.5 to increase readability." 3. Show how much the page is improved. In order to demonstrate all of the rules at work, you might want use one example page and show the process of applying one rule after another, till the end product is quite presentable.
