For the visuals I have a pull request against dlang.org:

https://github.com/dlang/dlang.org/pull/1317

The generated HTML still isn't the nicest, though.

One problem with that is that Ddoc isn't aware of lists, tables, etc. It can't
emit a <p> element for every paragraph it sees, because what's a paragraph to
Ddoc may become a list in HTML which must not be wrapped in <p>.

Making Ddoc drastically more content aware, i.e. going full Markdown, would be
a solution. It would need to be a separate documentation generator, though. A
sort of Ddoc2 with a opt-in compiler switch.

Another, less principled solution could be to emit something like <div
class="ddoc-paragraph"> instead of <p>. That is, Ddoc wraps every paragraph it
sees in a `DDOC_PARAGRAPH` macro with a nop default definition:

    DDOC_PARAGRAPH = $0

On dlang.org, we then redefine things like so:

    DDOC_BLANKLINE =
    DDOC_PARAGRAPH = <div class="ddoc-paragraph">$0</div>
