When you specify text-decoration property to an inline element (A), and then place a css defined block element (a span with "display: block") (B) inside it, the childrens of this element not inherit the text-decoration of the element A. ( Example: no. 1.1 )

When you try this example with a block element in the A position, the text-decoration property treated well. (Example 1.2)

Related spec: "When specified on an inline element, it affects all the boxes generated by that element; for all other elements, the decorations are propagated to an anonymous inline box that wraps all the in-flow inline children of the element, and to any block-level in-flow descendants."
