6 Assigning property values, Cascading, and Inheritance
@import not as the first declaration An @import is ignored if it is not the first statement in a style block.
Importing external stylesheets with @import An @import used to import external stylesheets.

Element selector precedence The element selector takes precedence over the font element 'color' attribute.
Universal selector precedence The universal selector and the 'color' attribute have the same specificity. The universal selector is applied since CSS takes precedence.
User style sheet precedence The 'font' element's 'color' attribute trumps the user stylesheet's universal selector. They have the same specificity but the font element is a virtual author rule.
Inheritance Children elements can inherit properties from parents.
Inheriting computed values The computed value of a font-size with a percentage is the percentage of its parent's font-size value. A nested element which also has a percentage applies the parents' specified value (which is inherited).	A
Non-inherited values If the cascade results in a value, use it.

Calculating specificity - Specificity 0002 vs. 0001 First-line selector with highest specificity wins - specificity 0002 takes precedence over 0001.
Calculating specificity - Pseudo-element vs. simple element The pseudo-element 'first-line' takes precedence over simple element selector.
Calculating specificity - Specificity 0001 vs. 0000 The element selector has the highest specificity - specificity 0001 takes precedence over 0000.
Calculating specificity - specificity 0003 vs. 0001 First-line selector with highest specificity wins - specificity 0003 takes precedence over 0001.
Calculating specificity - specificity 0003 vs. 0002 First-line selector with highest specificity wins - specificity 0003 take precedence over 0002.

6.1 Specified, computed, and actual values
6.1.1 Specified values
list-style - initial value 'list-style' property is a shorthand notation that sets the three properties 'list-style-type', 'list-style-image' and 'list-style-position'. If one of the 3 list-style properties is not specified explicitly, then such 'list-style' property is assigned its initial value as indicated in its property definition.	G

Inherit keyword Children elements inherit the parents color given the 'inherit' keyword.
Inherit on non-inherited properties Inherit can be used on properties which are not normally inherited.
Inherit on the root element If the 'inherit' value is set on the root element, the property is assigned its initial value.
