I wasn’t planning on redesigning my weblog—but then I was recently reminded that you can do shadows and rounded corners using new CSS bits in the latest WebKit.
-webkit-box-shadow creates shadows. -webkit-border-radius creates rounded corners.
Check the website with a browser that supports the CSS (i.e., Safari) and with a browser that doesn’t support it (e.g., Firefox). CSS3 makes round corners (and a bunch of other designs) really effortless.
At this moment, scrolling in the website is slow and takes extra CPU usage.
