Few issues in the (upcoming) doc

Seems to be a busy day, but I'd like to drop some notes on what I've seen from the next documentation:

• Like I said, would be nice to have a mention of css-ing with style key, and some integration within existing/new examples.
• DOM differences should include CSS camelCasing and a link toward the form section (with the new defaultValue and all).
• The part on DOM differences is currently in the reference section and is not obvious enough imo.
• Self-closing tags are always ok in React (?), even on elements you wouldn't normally self-close: <span />, <div />. Although this might be in DOM differences, since it applies to every React component, it should probably be mentioned elsewhere. E.g. it's obvious now that <Hello /> is possible, but it's actually not mentioned (unless I missed it) that <Hello>hi</Hello> is also valid, and that what's inside goes into props.children.

It's been a while since we changed these docs. If these issues are still relevant, can you update with details and I'll reopen.
