Put the information you want people to read in the body of the information that they are already reading. No one looks all that gubbins that surrounds the meat of a web page any more than people look at or care about street furniture.
And, anyway what is the real distinction between official and homebrew? Is that like Organic and Homemade in a supermarket? A distinction that is often without a meaningful difference.
Canon vs. custom, I think. The point being that you don't want a random person complaining to their DM that they're not using the rule about magical trousers, when it was actually written by some random on the internet and added to a Wiki.

Well, official is the material written by the creator of the game (here WotC), which is supposed to be tested, properly edited and more or less balanced; homebrew is written by anyone: that doesn't mean it's lower quality or unbalanced, but there's less of a guarantee; so most GM will usually allow official content and forbid homebrew
Homebrew content in D&D can be ridiculously poorly-balanced compared to officially-published content, which is required to go through at least some internal testing by the game's managers and designers.
