Like my employer, Arena Media (also part of the Havas Media Group – another site I built) underwent a branding change at the beginning of 2013. Based on the same guidelines as Havas Media, the site had a bit more leeway and creative freedom.
I built the global site from scratch, based on PSD designs, with a responsive theme. The banner on the homepage can contain still images and HTML animations, overlaid with a custom font.
The United Kingdom site was forked from this, and uses much of the same code. The template files were then sold to the rest of the group and are being used independently. The Spanish site is nearing launch.
