[css-page-3] Very minor typo

[pcraig3]

Hi there,

I've been reading through the CSS page rules (very helpful, thank you!) but I noticed a typo that threw me for a loop.

Under 4.4. Cascading in the page context, the second paragraph beings: "The specificity of page a selector is computed ..."

Unless I am mistaken, the article ("a") should come before the word "page".

Thanks for the note! I've fixed this.
