O’Reilly Velocity Conference is Coming!
I wanted to give everyone a quick reminder that O'Reilly's Velocity Conference is coming up from June 24-26 in Santa Clara, CA. Velocity conference gets me super excited because it's the conference that focuses on front-end performance, not simply front-end techniques. Too often we're so happy when our widget, site, or app works that we don't take the time to stop, analyze performance, and adjust.
Velocity Conference addresses mobile and desktop performance, CSS performance, JavaScript performance, and network performance. Top speakers like Laura Swanson of Etsy, Stoyan Stefanov of Facebook, Pamela Fox of Khan Academy, and several other performance speakers will be sharing their knowledge and insight.
Discount Code: AFF20
Due to the big response of my first post, O'Reilly has provided me another discount code of AFF20 to get you 20% off the conference cost. Hang on to that cash for drinks, dinner, and networking. Or sweeten the pot for your employer by letting them know you're saving 20%. Either way, enjoy the discount code!

![CSS pointer-events]()
The responsibilities taken on by CSS seems to be increasingly blurring with JavaScript. Consider the -webkit-touch-callout CSS property, which prevents iOS's link dialog menu when you tap and hold a clickable element. The pointer-events property is even more JavaScript-like, preventing:
click actions from doing...
![MooTools Overlay Plugin]()
Overlays have become a big part of modern websites; we can probably attribute that to the numerous lightboxes that use them. I've found a ton of overlay code snippets out there but none of them satisfy my taste in code. Many of them are...
