You may be surprised to know how much people prefer the old conventional methods when it comes to navigating websites. Top companies have researched on the style of navigation that most people prefer, and the results have been in favor of the old conventional systems. However, if you are tempted to use a funky navigational style, like all links arranged in a circle, then resist your temptation and stick to the convention.
Everyone likes to be their own boss. This also applies to people visiting your website. So, if you have a particular style for your window that will look good only in a particular window size then drop your idea. Because, if you continue with the same, you will have to add scripts that will automatically resize the window of your website visitor and this can tick off people! So, go for a style that is flexible and fluid.
