Are there general css paths for drupal Is there a specific drupal way to focus on one specific part of a nodes element in the css path? For example if I change the H2 element within my theme css it changes all H2... How can I change one specific one on the page. The object is to be able to focus on particular elements to make them unique... If this is possible how do I write the style declarations?
Drupal allows your site to have many Themes installed. Themes can define their own HTML structure to make your site look a certain way. Drupal has a few themes the ship out-of-the-box.

Depending on the theme you use it may or may not contain HTML classes or ids in the source to easily target specific items on the page. Typically, themes and Core html is fairly darn flexible.

Looking at the Zen Theme HTML and CSS markup you can see it has fairly specific rules to get at and theme alot of the content from Zen and also core drupal themes: Useful CSS selectors to add to your stylesheets
