In visual art, the frame gives the art an extra edge and help highlight its best features.
However, the frame cannot be a master piece without great content. The same goes for web design. Designing a website is like designing a state of the art frame: it needs great content to be truly effective.
Before you being the process of redesigning your website, think about your content. Do you have high quality, relevant images to support your content? Do you already have written content or do you need a content writer? The more of your content you have ahead of time, the easier the design process will be.
