When I was in Porto a few weeks back, I took lots of pictures of the beautiful tiles. They reminded me of the ubiquitous repeating background images that were so popular on the early web. I was thinking about abstracting them into a collection of reusable patterns but now it looks like I’ve been beaten to it!

The new Clearleft website is live! Huzzah!
Many people have been working very hard on it and it’s all looking rather nice. But, as I said before, the site launch isn’t the end—it’s just the beginning.
There are some obvious next steps: fixing bugs, adding content, tweaking copy, and, oh yeah, that whole “testing with real users” thing. But there’s also an opportunity to have some fun on the front end. Now that the site is out there in the wild, there’s a real incentive to improve its performance.
Off the top of my head, these are some areas where I think we can play around:
- Font loading. Right now the site is just using
@font-face. A smart font-loading strategy—at least for the body copy—could really help improve the perceived performance.
- Responsive images. A long-term solution will require some wrangling on the back end, but I reckon we can come up with some way of generating different sized images to reference in
I’m looking forward to tinkering with some of those technologies. Each one should make an incremental improvement to the site’s performance. There are already some steps on the back-end that are making a big difference: upgrading to PHP7 and using HTTP2.
Now the real fun begins.

These icons-as-a-service could be really useful for making quick’n’dirty HTML prototypes.

Jason revisits responsive images. On the whole, things are looking good when it comes to browser support, but he points out that
scrset’s precursor in CSS—
image-set seems to have dropped off the radar of most browser makers, which is a real shame.

Harry clearly outlines the performance problems of Base64 encoding images in stylesheets. He’s got a follow-up post with sample data.

This is an interesting use of voodoo magic (or “machine learning” as we call it now) by Google to interpolate data in a small image to create a larger version. A win for performance.

This use-case for blend modes is making me thirsty.
Also: look who’s blogging again!

See, when I first heard about
background-repeat: round; I thought it was something to do with making things circular. But no, it’s about tiling a background image so that nothing gets cut off. The amount of tiling required is rounded to the nearest whole number.
Now I get it.

This could be a handy replacement for some Google Charts images of graphs. It uses SVG and is responsive by default.
I bet it wouldn’t be too tricky to use this to make some sparklines.

A step-by-step walkthrough of how GitHub has tweaked its Content Security Policy over time. There are some valuable insights here, and I’m really, really happy to see companies share this kind of information.

This is really, really clever. You can’t use generated content (
:after) on replaced content. The
img element is replaced content …but only when the image actually loads. So if the image fails to load, you can apply specific fallback styles (using

A very handy tool for figuring out breakpoints for responsive images.
Upload an image in its largest size, play around with the settings, and then generate the breakpoints, the markup, and the resized images for each breakpoint.
