Fixing an element containing site navigation or branding to the top or bottom of the viewport is a common design trend. Most solutions I’ve come across use a combination of fixed positioning and JavaScript to mitigate any side-effects. I’ve found a better solution that uses 'sticky' positioning... Try the clamped content demo The common method — position: fixed Setting an element’s CSS position pr
In most browsers, tucked away behind a feature flag, is an exciting new API for creating VR experiences on the web. However, creating content for this new medium could potentially see you at the bottom of a steep learning curve — but does it have to? There are a couple of options available for creating VR content on the web. The first requires a working knowledge of both the WebVR and WebGL APIs.
CSS transforms make it easy to manipulate an element in 3D space without worrying about the complex maths involved. But what if you want do more than transform elements? How can you shade an element or test if two transformed elements intersect? To do that you need access to the elements vertex data — unfortunately that data doesn’t exist. In this post I’m going to explain how to generate vertex d
This article demonstrates a technique to get content in front of visitors as quickly as possible by asynchronously downloading stylesheets to prevent them from blocking page render. Warning! I posted this with the best of intentions, but it would be irresponsible not to make readers aware of the following issues. Community feedback is coming in thick and fast (something I'm very grateful for) and
Last year I created a demo showing how CSS 3D transforms could be used to create 3D environments. The demo was a technical showcase of what could be achieved with CSS at the time but I wanted to see how far I could push things, so over the past few months I’ve been working on a new version with more complex models, realistic lighting, shadows and collision detection. This post documents how I did
Webkit will render an element differently when the responsibility of painting it is passed from the CPU to the GPU. This switch can trigger unintended rendering artefacts which, although most obvious in text, apply to all types of content. Changes in antialiasing With the exception of IE11, every browser I tested uses subpixel antialiasing on the CPU. If an element is promoted to the GPU in curren
This article demonstrates how to use CSS transforms, perspective and some scaling trickery to create a pure CSS parallax scrolling website. If you find this article useful and want to explore CSS Parallax further, you may find my follow-up article "Practical CSS Parallax" an interesting read. Parallax is almost always handled with JavaScript and, more often than not, it’s implemented badly with th
Pure CSS parallax scroll demo #3 by Keith Clark. Please read the blog post for more information.
This is demo of a CSS powered 3D environment. Geometry is created with HTML elements and CSS transforms. Textures and lightmaps are composed by layering multiple background-images and colour is applied using CSS blend-modes. A Keith Clark experiment.
