DESCRIPTION
You just received an image or layered file from marketing with the design for an application you need to build. You're wondering what to do. How do I translate this into a usable APEX template? APEX provides great flexibility that allows your applications to fit within your corporate visual theme, but many people don't realize that the APEX built-in themes are not static or your only option. HTML and CSS can be daunting when your expertise lies within the database realm. This session will show you that a little understanding goes a long way.

Sprites
Similar to one image for “on” and “off” states Sprites aren’t little images, a sprite is one big image!

“Reducing the number of HTTP requests has the biggest impact on reducing [page loading] response
time and is often the easiest performance improvement to make.”
"Performance Research, Part 1: What the 80/20 Rule Tells Us about Reducing HTTP Requests" by Tenni Theurer on the Yahoo! User Interface Blog
Sprites
• Combine multiple images into one
• Build your own sprites
• Search for services that create sprites
Styling two state elements
• You require two images!
1.normal 2.hover!
• Alignment and size must be exact!
• But we’ll combine them into one file (sprites)
Styling state elements• Add multiple state images to your file!
1.normal 2.hover!3.selected 4.selected hover 5.alternative 6.etc... !
