Graham bemethavinci The raw blog on xtgem uses the classes set in the xtgem_template.css built in site templates
The global_stylesheet.css is used to hold custom classes of your own to extend or overrule settings in that template
These two are the css files linked automatically to all your sites pages
Thats it really you could just use one of the templates and create a reasonable functioning site without ever even opening a css file or html page in text editor
Just use the building tool

or you can delete the contents an add your own values
or you can delete the files and ignore them and link your own css
or any combination of any of the above
