Zen Cart Stylesheets
Zen Cart(tm) stylesheets are located in this folder: /includes/templates/YOUR_TEMPLATE/css
What follows is a description of how one can use Zen Cart's built-in power to pull certain stylesheets for certain conditions.
The CSS files are sent to the browser in this order: (and alphabetically within each case of more than one match):

             style*.css // are always loaded and at least ONE should contain site-wide properties.

language_stylesheet.css // changes to ALL pages, when that language is used
          page_name.css // changes to one page (use index_home.css for "just the home page")
 language_page_name.css // changes to one page, when that language is used
               c_??.css // changes to all info pages in a category
      language_c_??.css // changes to all info pages in a category, when that language is used
               m_??.css // changes to a manufacturer's listing page
      language_m_??.css // changes to a manufacturer's listing page, when that language is used
               p_??.css // changes to a product's info page
      language_p_??.css // changes to a product's info page, when that language is used
             print*.css // printer-friendly global usage site-wide changes for printing-only


The 'stylesheet.css' always loads first and should contain the bulk of your CSS selectors. Each file loaded takes priority over previously loaded file(s). To save loading time, only new selectors or selectors whose properties you wish to change should be in the subsequent optional CSS files. You can have different overrides for the same page, in different languages, because the two would never be called at the same time.
If someone selected the French language on your site, the 'french_stylesheet.css' would also be loaded. It should only contain the site-wide changes you want to make to 'stylesheet.css'. For example, change a 'background-image' for your French customers.
If someone went to any of the other pages, that page's CSS file would be loaded. Possibly you want different 'background-image' & 'background-color' on each of 'page_x' pages. Possibly you do not want a border around '.plainBox' most of the time, but on a couple of pages you do... and on one of those pages you want it in black and the other in red.
Possibly you created a NEW tag and did a <span class="newtag"> in your Privacy Statement. It is defined in only one CSS file, 'german_privacy.css' as '.newtag { text-transform: uppercase }' Because, in Germany, that phrase must be in all CAPS, but not in other countries.
Use your CSS files and the standard tags as much as possible, just change their properties when needed. If possible, DON'T HACK the core code. Use your CSS files to do the work for you. When the style coding has been removed from the Zen Cart code and people have to decide if they want to go without the upgrade ~or~ undo all their hacks and finally learn about CSS... your site will still be up and running.
