This is Variant Creative, a 3-column layout with a page width of 980 pixels. It was in part inspired by the popularity of the andreas01 design, a free website template originally released in 2005 which has been used on hundreds of thousands of websites and blogs throughout the years. Variant Creative uses a similar general layout, but with a different style and with a non-standard and eye-catching header. The source file for the header image is included in the template .zip as a .PSD document, for easy customization.
I kindly ask that you leave the credit text and link (the one that says "Template design by Andreas Viklund" in the footer) since that is a nice way of supporting my template design work. But it is no requirement, just a request. Do what works best for you!
