119 slides from Sarah on a wide range of SVG magic (with code).
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!
Google have released this encoder for JPEGs which promises 20-30% smaller file sizes without any perceptible loss of quality.
A Mac app for converting PNGs and JPEGs to WebP.
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.
Images, videos, sounds, and 3D models are now available from the European Space Agency under a Creative Commons Attribution Share-alike license.
Harry clearly outlines the performance problems of Base64 encoding images in stylesheets. He’s got a follow-up post with sample data.
The text detection API is still in its experimental stage, but it opens up a lot of really interesting possibilities for the web: assistive technology to read out text, archiving tools for digitising text …it’s all part of the nascent shape detection API.
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.
Yummy wallpapers for your desktop, tablet, and phone, from NASA and ESA.
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.
We’ve got Space Ipsum for text. Now we have SpaceHolder for images.
