Web design: More HTML5 semantics

The markup of a general article on this site is now almost perfect:

<article id="ITEM170">
<header>
<h2>Boktips: <cite>Svenska skrivregler</cite> från Språkrådet</h2>
<dl class="metadata" lang="sv">
<dt>Notis</dt>
<dd><a href="article.asp?ItemIndex=170">170</a></dd>
<dt>Datum</dt>
<dd><time>2013-10-18</time></dd>
</dl>
</header>
<p>Det var med skräckblandad förtjusning [...]</p>
</article>

(This is from the Swedish site, so <html> has lang=sv.) Notice the use of the <time> element to mark up the date. Since the date string is already machine-readable (in one of the formats given in the HTML5 specification), there is no need for the datetime attribute. The CSS and the rendering is shown below.

/* Newsitems */

article { }
article header h2, article header p {
margin: 0;
}
article header {
color: black;
background: #EEE;
padding: 4px;
border: 1px solid black;
}
article header dl, article header div {
margin-top: 1em !important;
}
article {
margin-bottom: 4em;
}
:lang(sv) article:lang(en) header h2:after {
content:url("https://rejbrand.se/pix/Flag_of_the_United_Kingdom_small.png");
padding-left:0.5em;
}
:lang(en) article:lang(sv) header h2:after {
content:url("https://rejbrand.se/pix/Flag_of_Sweden_small.png");
padding-left:0.5em;
}

Rendering of the above HTML with the default stylesheet

These articles are considered the standard ‘articles’ on my site, so there is no need for a class attribute on the <article> element.

Now, I have also improved the markup of guestbook messages, as shown in the following message:

<article class="guestbookMessage" id="MSG343">
<header>
<h2>
Dina dokument
</h2>

<dl class="metadata">
<dt>Från</dt>
<dd>Jan</dd>
<dt>Datum</dt>
<dd><time>2014-11-06</time></dd>
</dl>

<div>
<a href="gb_response.asp?MessageIndex=343">Läs svar från Andreas Rejbrand</a>
</div>

</header>

<div class="messageText">
<p>Hur kommer det sig att du väljer att skriva dina dokument i Word [...]</p>
</div>
</article>

The rendering of this new semantic markup should match the original style of my guestbook, as shown in the following screenshot.

Rendering of the above HTML with the (old or new) default stylesheet

Here I use a special class to indicate that this is not a standard ‘article’ but a guestbook message. And obviously, a special class is needed in order to style guestbook messages differently from the standard ‘articles’. The new CSS is

/* Guestbook */

article.guestbookMessage {
margin-top: 4em;
margin-bottom: 4em;
width: 75%;
}

article.guestbookMessage header {
background: inherit;
color: inherit;
border: none;
padding: 0;
margin-bottom: 1em;
}

article.guestbookMessage header dl, article.guestbookMessage header div, article.guestbookMessage .messageText {
background: #DDD;
color: black;
padding: 4px;
border: 1px solid black;
}

article.guestbookMessage header div a {
font-weight: bold;
}

I clearly need the inherit value, because I want the header to be transparent (and, indeed, the parent element is not guaranteed to be black text on white background). But this gave rise to a minor problem, because this CSS value is not supported (at least not properly) in IE 7 and below. The solution is simple enough, however. I simply added the following code to my IE7-and-below stylesheet:

article.guestbookMessage header {
background: white; /* IE ≤7 doesn't understand inherit */
color: black;
}

This assumes that the parent indeed has black text on a white background, but this is the case if the default stylesheet is used, and alternate stylesheets are not supported in IE 7 and below anyway.
