Although this isn’t technically CSS related, I think it’s a sufficiently valuable resource to share. Shifting Pixel has just released their “Smart Image Resizer” PHP script. Basically, this script allows you to upload one large-sized version of an image and then call that image via a special URL in your image’s SRC attribute. The attribute points to the PHP script, which creates the size of image you need, caches it, and serves up the new image. The benefit is you can use one source image in many places and sizes on your website without having to either create a bunch of derivative images by hand or rely on the browser’s shoddy resizing algorithms.
Here’s a list of eight great CSS tips from the minds behind CSS Globe. And the best part? Each CSS rule contains only a single property: value pair, meaning these are some of the smallest and easiest-to-learn tips around. That doesn’t mean they’re obvious, though: I learned a thing or two, myself. And be sure to read through the comments for a lively discussion on the tips, and a few extras submitted by readers.
