    Flow-Relative Mappings</h3>
 
   <p>Flow-relative directions are calculated with respect to the writing mode
-   of the element and used to abstract layout related to padding and border
-   properties. For example, if an element had computed values of &lsquo;<code
-   class=css>direction: ltr; writing-mode: vertical-lr; text-orientation:
-   vertical-right</code>&rsquo;, &lsquo;<code
-   class=property>padding-top</code>&rsquo; would give its start padding, and
-   &lsquo;<code class=property>padding-left</code>&rsquo; would give its
-   before padding.
-
-  <p>Flow-relative directions are calculated with respect to the writing mode
-   of the <em>parent</em> of the element and used to abstract layout related
-   to the margin properties and the &lsquo;<a href="#top"><code
+   of the <em>containing block</em> of the element and used to abstract
+   layout rules related to the box properties (margins, borders, padding) and
+   any properties related to positioning the box within its containing block
+   (&lsquo;<code class=property>float</code>&rsquo;, &lsquo;<code
+   class=property>clear</code>&rsquo;, &lsquo;<a href="#top"><code
    class=property>top</code></a>&rsquo;, &lsquo;<a href="#bottom"><code
    class=property>bottom</code></a>&rsquo;, &lsquo;<a href="#left"><code
-   class=property>left</code></a>&rsquo;, and &lsquo;<a href="#right"><code
-   class=property>right</code></a>&rsquo; properties. (For the root element,
-   which has no parent, the values of the writing mode of the element is used
-   instead.)
+   class=property>left</code></a>&rsquo;, &lsquo;<a href="#right"><code
+   class=property>right</code></a>&rsquo;) For inline-level elements, the
+   writing mode of the <em>parent element</em> is used instead.
+
+  <p>For example, the margin that is dropped when a box's inline dimension is
+   <a
+   href="http://www.w3.org/TR/CSS21/visudet.html#blockwidth">over-constrained</a>
+   is the end margin as determined by the writing mode of the containing
+   block.
 
   <p>The <a
    href="http://www.w3.org/TR/CSS21/box.html#collapsing-margins">margin
    collapsing rules</a> apply exactly with the <em>before margin</em>
    substituted for the top margin and the <em>after margin</em> substituted
-   for the bottom margin. Similarly the padding and border on the same side
-   as the before margin is substituted for the top padding and border, and
-   the padding and border on the same side as the after margin for the bottom
-   padding and border. Note this means only before and after margins ever
-   collapse.
-
-  <p class=note>The parent element is used instead of the containing block,
-   because the benefit of using the containing block is very rare, but the
-   cost to implement it is rather high for implementations that do
-   abstract-physical mapping at cascade time.
-
-  <p>The start and end directions are also used for inline layout as follows:
-   
+   for the bottom margin. Similarly the before padding and border are
+   substituted for the top padding and border, and the after padding and
+   border substituted for the bottom padding and border. Note this means only
+   before and after margins ever collapse.

+   of the element and used to abstract layout related to the element's
+   contents:
