Ever since I last reworked the Westciv site I've received a constant stream of emails asking how I achieve the transparency effect on the logo in the top left corner. I lost track long ago of how many people I promised a tutorial on the subject. Well, here it is. The added bonus for waiting so long is that here you won't just learn how I create the visual effect as the page scrolls. I've also written about how I made the background image into a link to the home page which will always be there no matter how far someone scrolls down the page.
