If I had chosen to use GIF instead, I would have been limited to GIF’s binary transparency. The result would have looked like Figure 5-4. I think we can all agree that’s not good enough. Figure 5-4. www.49abcnews.com header, nightime, with GIF image instead of PNG The translucent HTML overlay A very common graphic design technique is to overlay a photo or other image with a partially transparent region, usually containing text. This allows for readable text without completely obscuring the view of the image below. Designer Wilson Miner (www.wilsonminer.com) uses this to great effect on the Gingeroot jewelry site (www.simplygingeroot.com), as you can see Figure 5-5. Figure 5-5. www.simplygingeroot.com, designed by the talented Wilson Miner (www.wilsonminer.com) chapter 5 Creative Use of PNG Transparency in Web Design 113
114 Wilson includes his transparent region and text in the JPEG image. He created them beforehand in Photoshop. This works fine, and it is totally appropriate for the site’s needs. But what if the text in the translucent area needed to change very frequently—perhaps even be different for every visitor? In this case, it wouldn’t be practical to put the text in the image. The text would need to be crafted in HTML and CSS. Using PNG’s transparency alpha channel, we can emulate Wilson’s style without putting the text in the image itself. I’ll start with a photograph of my daughter, Haley Madysan, and put it into a simple XHTML page with some basic CSS styling (this is haley_example/index.html in the code download). Note that I’m using an embedded CSS style sheet for demonstration purposes only. In real-world situations, using a linked external style sheet typically provides more flexibility, less code repetition, and more practical file management. Haley's web site body { font-family: "Lucida Grande", Helvetica, Arial, sans-serif; background-color: #304251; color: #304251; margin: 20px auto; width: 720px; } #feature { position: relative; width: 720px; height: 439px; } #feature-content { position: absolute; bottom: 0; left: 0; height: 125px; width: 720px; background-color: #dfdfdf; } #feature-content h1 { margin: 0; padding: 0; line-height: 125px; padding: 0 30px; font-weight: normal; font-size: 2.3em; } #feature-content a { float: right; font-size: .6em; color: #fff; text-decoration: none; text-transform: uppercase;
