I re-launched my new website today. I have kept the design the same and have moved into the cutting edge future with HTML5 and CSS3. One of the exciting things now is to be able to use CSS3 rounded corners and drop-shadows in the build rather than images. This process speeds up development time and even page download time as there are fewer server requests and page weight.
The web experience is evolving and the consensus that has evolved is that web pages don`t have to look exactly the same in every browser. If one browser can render rounded corners then allow that. This is all about moving ahead and using great technologies that are available to us now.
