+  <p>
+    This section defines that
+    when a child box establishes an orthogonal flow,
+    the used <i>block size</i> of the child is
+    the <i>inline-axis</i> <var>min-content</var> and <var>max-content</var> of the parent.
+  <p>
+    This means that when applying shrink-to-fit formula to a box
+    such as an inline-block or a table-cell,
+    and if its child establishes an orthogonal flow,
+    the calculation dependency must be changed so that
+    the sizing phase of the child runs first and
+    its used <i>block size</i> becomes an input to the shrink-to-fit formula of the parent.
