Lucid is an excellent PSD template for a simple one page website. This could be a particularly fitting design for showcasing an app, software or technology product.
The layers in the PSD are clearly named, so you’ll be up and running with it in no time. Simple to customise it’s built on a 12 column grid. This template would work beautifully with a Bootstrap or Foundation build. It even comes with three alternative headers: standard, contact form, and a subscription form.
