Surfin’ Safari - Blog Archive » How WebKit Loads a Web Page
Before WebKit can render a web page, it needs to load the page and all of its subresources from the network. There are many layers involved in loading resources from the web. In this post, I’ll focus on explaining how WebCore, the main rendering component of WebKit, is involved in the loading process. WebKit contains two loading pipelines, one for loading documents into frames and another for load
Announcing SquirrelFish
“Hello, Internet!” WebKit’s core JavaScript engine just got a new interpreter, code-named SquirrelFish. SquirrelFish is fast—much faster than WebKit’s previous interpreter. Check out the numbers. On the SunSpider JavaScript benchmark, SquirrelFish is 1.6 times faster than WebKit’s previous interpreter. What Is SquirrelFish? SquirrelFish is a register-based, direct-threaded, high-level bytecode eng
Safari Hits 6.25% Market Share
The latest browser market share data is in, and Safari has hit 6.25%, breaking 6% for the first time. Last month’s share was 5.81%, so this is a significant increase. It was only nine months ago that Safari broke 5%. Safari market share has now almost tripled from 2.14% in June 2005, when the WebKit Open Source project launched. This growth, combined with recent WebKit adoption in projects such as
CSS Canvas Drawing
Currently the set of images you can use from CSS consists of the following: Bitmap Images (PNG, GIF, JPG) SVG Images Gradients A notable missing ability when compared with explicit DOM content is programmatic drawing into CSS images. The <canvas> element represents a foreground bitmap image that can be drawn into programmatically, but – aside from inefficient hacks involving toDataURL – there hasn
Surfin’ Safari - Blog Archive » querySelector and querySelectorAll
Posted by David Smith on Thursday, February 7th, 2008 at 2:41 pm A familiar and unpleasant sight in web applications is fragile code traversing the DOM to get to certain elements or collections of elements. Chains of getElementById("something").parent.parent are all too common, hurting both readability and flexibility. As a result, many javascript libraries have implemented functions to use the po
Surfin' Safari - Blog Archive : HTML5 Media Support
Another nice feature from the HTML5 draft specification is now available in the WebKit nightly builds for Mac OS X. The new HTML5 <video> and <audio> elements add native support for embedding video and audio content in web pages. They also provide a rich scripting API for controlling playback. Adding video to a web page is almost as simple as adding an image: <video src=sample.mov autoplay></video
CSS Animation
We have another cool new CSS feature to talk about: animation specified in CSS. There is a lot of ground to cover here, so we’ll start with the basics first. The simplest kind of animation that we’ve added support for is called a transition. Normally when the value of a CSS property changes, the rendered result is instantly updated, with the element in question changing immediately from the old pr
Surfin’ Safari - Blog Archive » WebKit Does HTML5 Client-side Database Storage
The current working spec for the HTML5 standard has a lot of exciting features we would eventually like to implement in WebKit. One feature we felt was exciting enough to tackle now even though the spec is still in flux is client-side database storage. So for the last few weeks andersca, xenon, and I have been cooking up an implementation! The client-side database storage API allows web applicatio
