As usual, I didn’t design this one, I just built it. A little bit of jQuery, a lot of CSS, a splash of embPerl and Google Maps API on the contact page, all built on top of an HTML5 template (with Modernizr providing the shiv for older browsers). The homepage uses a variation on my simple slideshow which interacts with the main navigation tabs.
For fun and practice, I built a version of the homepage at http://highroad.impactcsg.com/index.html#3d (since it’s a hash, you may need to reload the page) that animates the logo as you mouse over the header using CSS 3D, for those browsers that support it. The designers didn’t want to try and sell it to the client, since the logo itself is brand-new and they wanted to establish it before they tried playing with it. Which makes sense, but it seemed like a tragedy to just throw such a fun little toy in the trash, so there it is.
The other thing worth noting about this site is its distinct mobile identity. In the spirit of responsive design, we created a separate iPhone/Android-friendly stylesheet for the site (without changing the URL), complete with its own version of the homepage banner slideshow and collapsing navigation menus.
