Declaring styles between the <head> tags creates global styling. Using the method I described creates a localized style -- specific only to the element the style is attached to.
The navigation menu in SCC is created using <li> tags and is styled on line 30 of the default.css file "ol, ul {list-style: none outside none;}". A bulleted list within a product's description will acquire the styles defined in the css file, which hides the bullet. That is why Mark would need to add the local style to the <ul> element (so the bullet will show).
Book,
