Google have released their own style guide for HTML and CSS code.
It will be interesting to see how much of it they apply in future changes to Blogger templates
But for Bloggers who do a lot of modifications to their own template, there might be some useful tips. I especially like the one about putting CSS rules into alphabetical order for maintainability.
Doing this would mean adding CSS rules manually rather than than through Design > Customize > Advanced > Add CSS
And it will be harder to do a code-compare to see the difference between our customized template and the current standard-issue ones. But storing like-named rules together appeals to me more than just tagging new ones on the end.
