This is a pretty wacky experiment in altering font size based on the user’s distance from the screen (allow the page to access your camera and enable the “realtime” option for some real fun). I don’t know how much real-world application this has, but it’s a cute’n’fun exercise.
This looks like a really handy tool for reducing the file size of JPEGs without any perceptible loss of quality (in much the same way that ImageOptim works for PNGs)—available as a Mac app or an installable web service.
Once again I’m getting all my CSS3 information from Jonathan. This time he’s discovered the vw and vh units which allow you to specify sizes relative to the size of the viewport.
Another browser-based tool for viewing the same site at different sizes, but this one displays them all the same time, side by side.
Another browser-based tool for testing your responsive designs at different screen sizes.
Remy created this tool for resizing a viewport to figure out where to put the breakpoints in your media queries.
A handy little service for viewing sites at different dimensions. Just be aware that it doesn’t actually emulate different devices.
Well, ya learn something new every day …or at least I did. I had no idea about the rem unit—relative em—for font-sizing in CSS.
