Thanks for the detailed review, Rob!

It's great to get this kind of in-depth feedback early on. If you don't
mind, I'd like to expand on some of the reasoning behind the choices so far,
and correct some errors. :)

Agreed, this is just what ZopeSkel produces by default — and I don't touch
stuff I don't know how works. If anyone wants to change it and make sure
whatever registrations that reference it are updated, feel free to do it.
Last time I tried, my theme product was not functional anymore.

The idea is to have a final review at the end where we remove all the files
that aren't useful for the core theme. It's quite shocking to see just how
much crap is required in Plone 3 to add some simple templates. But yes, as
few files as possible is definitely the goal.

This is valid CSS3, and is also what we're already using CSS3 properties in
Plone 3. I'm not sure whether the validator is showing regressions, or
what's going on — I'm pretty sure I didn't get errors on rgba properties
earlier, but I might be wrong.

There was one legitimate error (cursor property), which I have fixed. The
rest seem like validator software bugs. :(

I know people have a reflexive dislike of !important, and I took great care
not to use any in the main style sheets. However, for the state coloring,
they are necessary, since you don't actually know what kind of elements they
are used on, and what other CSS is applied. The state color should always
take precedence when it's specified, so we have to use !important.

I agree with the principle of not using !important, but this is one of the
few cases where it is actually warranted.

> - Html validation failed with 20 errors and 32 warnings.

If you switch the validator to HTML5 and add the doctype as noted, there are
no errors in templates I tested. An important concern when deciding on
whether to adopt HTML5 or not was whether pointing the validator at it would
cause issues — but luckily it already supports HTML5.

These are valid concerns.

This is allowed in HTML5.

This is allowed in HTML5.

See above. ;)

I couldn't find any from my casual testing. Which templates were these? Note
that we supply empty alt tags if the image has no usefulness to the meaning
of the page.

FWIW, it passes the accessibility tester at http://wave.webaim.org.

Good catch, thanks! This is a legitimate issue, but seems to be unrelated to
the theme. The theme CSS has dl.actionMenu.deactivated dd { display: none; }
— but it seems that the menu rendering code doesn't apply this class anymore
(or does it using JS). I can't really tell where the "deactivated" class
supposed to come from. I suspect the same bug exists in current Plone 3
releases.

Right, there were still some px values left. Fixed.

That's not what that guideline says. It shows you a *technique* to help you
make sure that you can easily see that there's enough contrast by looking at
the percentage/hex value, but that doesn't mean that there's anything
magical about using hex/percentages over named colors. The few colors we use
that named (gray and red on white) have plenty of contrast.

Of course, when constructing an accessibility validator, it's easy to add a
rule like that to trigger a warning, which is a good idea, since a lot of
the named colors aren't good combinations (red on orange, etc). But in our
case, we're OK.

OK, made them a little darker. Have a look now.

Where? I couldn't see any when testing a couple of different templates.

It's called the "print" menu entry in your browser. ;)

If you want, we can avoid rendering this link if you don't have JS enabled —
but I have removed it altogether from the default layout, and let it be up
to the integrator to enable this viewlet again, since print / send to are of
questionable value.

It's a requirement that used to be common in RFPs etc, but seems to be
eschewed in favor of Facebook/Twitter buttons these days — which are equally
annoying and not used by anyone — statistically speaking — either. It mostly
means "we are hip to social media" these days, and is mostly present on
sites that aren't. Can you tell I don't like them? ;)

The registered trademark symbol is supposed to be superscript, do you see
any other use that conflicts with this?

My goal was to change as little as possible of the existing markup. If we
introduce new tags for the h5s, we might break existing themes. I'm happy to
make this change in Plone 5 where we are doing more significant markup
changes, but I don't think it's worth being purist about it at this point.

I'll beg to differ, sorry — they do the same thing, show aspects of a
content type, the fact that some reload and some don't is a different issue.
They are trying to express the same concept, and while the implementation
isn't ideal, they are expressing the same kind of grouping (although on
different levels). We're getting rid of these in Plone 5, so they will be
short-lived anyway. Nobody really wants two levels of tabs. :)

Some colors are non-negotiable — you need blue links, and I reused the same
blue for the global navigation (just inverted). There's a lot of
documentation that talks about "the green bar", so in the interest of
keeping things simple, I added that color too. Those are the two only
colors, and they are trivial to change, and examples of how to do it are
provided in ploneCustom.css.

The point of the statement was to address all the other use of color, which
makes it hard to theme Plone to a particular visual profile. The two colors
used now can be changed by uncommenting two new values in ploneCustom.css,
and nothing else will conflict with a given corporate visual profile.

See earlier comments. 0 errors if you set it to be HTML5. :)

The markup is pretty messy already, but I don't think we should try to fix
this until Plone 5 to keep things simple for existing themes.

Not sure what you mean here — the portlets are already wrapped in the
<aside> tag, are there any other obvious tags that you think are missing for
portlets/viewlets?

Apart from a couple of new tags in main_template, XHTML1 and HTML5 are the
same. I don't see the issue, and Plone has historically been and early
adopter wrt. these things as long as they actually work — which they do.
Browsers that don't understand HTML5 will just render as HTML4 (or XHTML,
should you choose to use that MIME type). We were the first CMS to use XHTML
and CSS2, and I'd like us to stay with the times. This kind of stuff does
send the right signal to developers, which is something we sorely need on
several levels. :)

Making it configurable is not an option as far as I can see, as XHTML is a
subset of HTML5, but not the other way around. It would also be hard to
maintain. Let's pick one. It's pretty clear which one has a future at this
point. :)

Print and mobile have been added. Feedback welcome, they are both relatively
simple.

Thanks again for the fast swift review!
