The site is a single page, using JavaScript to switch the tabbed content, so each part would be a good candidate for the section element. It depends on your interpretation of the nav specification, but I would say as it’s their content the social links could go into a nav.

The site is really well constructed and makes good use of headings to create a nice outline. Other boxes are ticked too including hcard microformat and good use of new form input types and attributes. There is a little WAI-ARIA which could be rolled out to cover banner, navigation, form, complementary and contentinfo roles.

This site is really well marked up, and the author clearly has a good understanding of when and how to use sectioning content. The placeholder attribute is used in the contact form, but new input types e.g. type="email" and type="tel" are not. Using these along with the required attribute could improve the form.

Decent use of new structural elements, although the fact that footer isn’t sectioning content has resulted in the un-nested facebook heading in the footer inadvertently becoming the document title as it is the highest level heading in the body.

One notable feature of this site is the use of SVG for the map in the sidebar, and it’s good to see microformats used on the contact details. The site could benefit from the use of some explicit sectioning content and new form input types.

The site uses new HTML5 structural elements, and the document outline is well constructed. It’s also nice to see block-level links in use in the nav just above the footer.

A lot of care and attention has gone into the markup of this website. Shortened doctype, script elements and stylesheet link elements, WAI-ARIA landmark roles, input type="email", input type="tel" and microformats are used throughout the site. Not only that but the document outline is spot on, with section and article used appropriately.

There is room for some small improvements though. The content of the figure in the page footer couldn’t really be said to be necessary for the understanding of the surrounding content, so aside would be a better choice. There are also headings that are hidden using CSS clip. If there’s no need for the heading it can be left out.

The site uses the HTML5 boilerplate as a starting point, and some new elements to markup the content. The document outline is good and the developer seems to understand the proper use of the section element. A couple of things could be done to improve the site: small could be used for the copyright notice in the footer, and although contact details are marked up using the hcard microformat, the correct class to use is vcard.

The site is marked up using plenty of new HTML5 elements, and the blog section on the home page is a nice example of a section with nested articles. The agenda section uses the same structure but the articles are untitled. It would be better to use the tabs as article headings and position them with CSS.

The site is a straightforward one with new HTML5 elements used to mark it up, as well as some custom data attributes in the portfolio slider. There is a section used to wrap a large block of content where div would have been more appropriate, and the type attribute can be dropped from the stylesheet link elements.
