+ <p>The input to the computations described in this module is:
+
+ <ul>
+ <li>a set of parsed style sheets
+
+ <li>the initial value of each property
+
+ <li>the title of the preferred style sheet (if any)
+ </ul>
+
+ <p>The output of the computations described in this module is a specified
+ value for all properties on all elements.
+
+ <p>In order to find the specified values, implementations must first
+ identify which statements that apply to the document. This is done by:
+
+ <ol>
+ <li>Starting out with all author style sheets specified in the document,
+ as well all user and UA style sheets.
+
+ <li>Removing statements that have associated Media Queries <a
+ href="#MEDIAQ" rel=biblioentry>[MEDIAQ]<!--{{!MEDIAQ}}--></a> that are
+ false in the given context.
+
+ <li>Removing @import statements that do not match the title of the
+ preferred style sheet, if any. This is described in <a
+ href="#import">Importing style sheets</a> below.
+
+ <li>Removing @media statements that do not match the title of the
+ preferred style sheet, if any. This is described in <a
+ href="#import">Named @media rules</a> below.
+
+ <li>Expanding all remaining @import rules.
+ </ol>
+
+ <p>Then, for every element, the value for each property can be found by
+ following this pseudo-algorithm:
+
+ <ol>
+ <li>Identify all declarations that apply to the element (as described in
+ <a href="#SELECT" rel=biblioentry>[SELECT]<!--{{!SELECT}}--></a>)
+
+ <li>If the cascading process (described below) yields a winning
+ declaration and the value of the winning declaration is not ‘<code
+ class=css>initial</code>’ or ‘<code
+ class=css>inherit</code>’, the value of the winning declaration
+ becomes the specified value.
+
+ <li>Otherwise, if the value of the winning declaration is ‘<code
+ class=css>inherit</code>’, the inherited value (see below) becomes
+ the specified value.
+
+ <li>Otherwise, if the value of the winning declaration is ‘<code
+ class=css>initial</code>’, the initial value (see below) becomes
+ the specified value.
+
+ <li>Otherwise, if the property is inherited, the inherited value becomes
+ the specified value.
+
+ <li>Otherwise, the initial value becomes the specified value.
