Markup Review

Website of a Brazilian printing company.

The vcard on the left (which is actually within the header) is contained within a section element which has no heading, as is the emails area. Again there is no heading on this section element so it’s really only acting as a container, so a div would have been more appropriate.
The social media links on the far left shouldn’t be contained within a nav element as they are not the main site navigation.

Nice to see the contact form use some of the new HTML5 input types.

Remember that the type attribute is no longer required for the script element.
