When designing the new homepage for Questionable Research Labs (QRL), we wanted to try and create a place for the ideas behind us to shine through. Built using Jekyll, this site runs on Github Pages and makes full use of modern browser performance.
Github Pages + Jekyll
30% of the internet these days runs on the popular content management system Wordpress - with good reason. Wordpress is easy to use, has good support, and has extensive libraries of ready-to-use plugins and themes. However, with the new QRL site, we decided to make use of Jekyll. Instead of using PHP to generate the various site pages when someone visits them dynamically, Jekyll runs ahead of time and creates a static site. This has the advantage of decreasing server load as well as the time for users to begin loading pages.
The second advantage is that it means we have much higher control over the final output. With Wordpress, it is not uncommon for sites to be bogged down but dozens of stylesheets and scripts that don’t do that much to make the site “nicer”. This is because each addon and theme runs independently to both each other and the user content, leading to the possibility for redundancy. With Jekyll, site templates are made from scratch (or modified from simple existing templates) to match exactly the desired output.
1: Google Analytics 2: Internet Explorer Compatibility 3: look-ahead caching
While we did our best to become IE compatible, we included an if statement that runs a script if you use Internet Explorer. We also added another script that automatically gets the next page when you’re about to click on it.
Animations & Images
As viewers on Chrome and Firefox (perhaps others) will notice, many of the homepage elements feature a random gradient & changing colours effect. Initially, a concept for this was mocked up in Photoshop with the idea to pan around it using CSS:
This looked cool, but wasn’t quite as ‘random’ as we were hoping to achieve. So, using After Effects and some compression a gif version was made:
Zoomed in and added to the homepage, this also looked good. However, Gifs feature a number of weaknesses, one of the key being that they have a restricted colour palette. You can see that above with the sharp bands across the gif. Another weakness of this method is that gifs are terrible at compression when there are limited or no static parts, or when the colours are constantly changing. Because both are happening above, the only way to get it down to a small(ish) file size was to shrink it down to 128x72. Even then, it was still one of the largest images on the homepage at 282KB.
Finally, each frame of the video was exported as PNGs and batch compiled using a 7,542 character console command (thanks webpmux) into a single animated WebP. This final output still had a variety of compression artefacts, but was “good enough” at 135kb@320x180:
The rest of the images on the homepage were then scaled down and converted to greyscale JPGs. The background (also greyscale) was one of the hardest to optimize, as it has a very high detail. This means that any significate resizing or JPG compression ruined the look. We eventually settled for a somewhat compressed WebP at 276KB
