The Difference Between Anchors, Inputs and Buttons
One of the things I love about CSS is how easy it is to make one element look like another. In the example above, the first element is an anchor, the second is a button and the third is an input. I've overridden the click behavior of all three so they do the same thing. If all three elements look and behave the same, does it matter which one you use?

Remove Whitespace Between Inline-Block Elements
I remember being a young developer during the Internet Explorer 6 days and desperately wanting IE to adopt display: inline-block.

CSS vs. JS Animation: Which is Faster?

And, how is it possible that Adobe and Google consistently release media-rich mobile sites that rival the performance of native apps? This article serves as a point-by-point walkthrough of how JavaScript-based DOM animation libraries, such as Velocity.js and GSAP, are more perfor
Write Better JavaScript with Promises
You've probably heard the talk around the water cooler about how promises are the future. All of the cool kids are using them, but you don't see what makes them so special. Can't you just use a callback? What's the big deal? In this article, we'll look at what promises are and how you can use them to write better JavaScript.

REM to PX Browser Function with Sass
