Spritely.net Learning from Twitter An issue popped up on Twitter this past week that caused the web site to be generally unusable for many users. It appears as if attempts to scroll were unbearably slow and caused the site to be unresponsive. The Twitter team investigated and determined that if they reverted the version of jQuery that they used back to 1.4.2 from 1.4.4 the site would be responsive again. After more investigation they determined that the code that was slow was doing a contextual selector search for an item by class name, for example: $something.find(".class"). So – what happened? How did this come about? However, as with every performance change, while some things get way faster some things can also get slower. What’s interesting here is that we’ve been using querySelectorAll for our default selector engine in jQuery for quite some time now (doing $(‘.class’) would use querySelectorAll). This brings up the important point: Just how much faster is getElementsByClassName compared to querySelectorAll? So.
Parallax Scrolling and Its Usage in Web Design The parallax effect, also called parallax scrolling, is a special technique used in computer graphics at first, where background images move by the camera slower than foreground images. This is the actual concept where websites with parallax scrolling started. It was widely used in the gaming industry more than 10-15 years ago and it is still used today in different domains. In the past years the parallax effect started to be used widely in web design. Its popularity went through the clouds when Nike redesigned their website based on this concept. Their example can be seen in the showcase below the conclusion. The design concept started to be used because it is actually quite cool. Parallax Scrolling Examples Although this is usually the case, utilizing the parallax scrolling effect doesn’t have to limit you to a fake 3D effect. When they see it for the first time, people use to think that the effect is nice. Performance Issues New age technologies The idea behind it is simple. Scrolldeck

Fancy Scrolling Sites In the last year or so, there's been enough sites that do fancy things when you scroll down that it's kind of a trend. I thought I'd blog it, you know, for the sake of history. By "fancy things" I mean something happens when scrolling down besides the site scrolling down. Elements might move around in unexpected ways or change their size/shape/color/content in some way. So how do they do that? JavaScript. Know any others? Add them in the comments. Share On
