No To Spy Pixels
Almost no-one has given informed constent to being tracked through spy pixels in emails, and yet the practice is endemic. This is wrong. It needs to change.

Body Margin 8px | Miriam Eric Suzanne
I love this kind of spelunking into the history of why things are they way they are on the web!
Here, Detective Chief Inspector Suzanne tries to get to the bottom of why every browser has eight pixels of margin applied to the body element in the user-agent stylesheet.

Breaking the physical limits of fonts
This broke my brain.
The challenge: in the fewest resources possible, render meaningful text.
- How small can a font really go?
- How many bytes of memory would you need (to store it and run it?)
- How much code would it take to express it?
Lets see just how far we can take this!
Unraveling The JPEG
A deep, deep, deep dive into the JPEG format. Best of all, it’s got interactive explanations you can tinker with, a la Nicky Case or Bret Victor.
Pixels vs. Ems: Users DO Change Font Size – Evan Minto – Medium
I have to admit, I didn’t realise that text reszing behaved differently for user preferences compared to page zoom. For that reason alone, I’m going to avoid setting font sizes in pixels.
If 2 to 3% (or more!) of your users are relying on a custom font size, you should know that so you can either support that user preference or make a conscious decision to not support it. Doing anything less is frankly irresponsible, especially considering that users with larger font sizes may be using those sizes to compensate for visual disabilities.
PX, EM or REM Media Queries? by Zell Liew
Just recently on a Clearleft project, some of us were discussing whether there was a reason not to use rems instead of ems for media queries. Apart from one older browser implementation difference, we couldn’t come up with much.
Some in-depth research here supports the use of em values for media queries. Very good to know.
Retina revolution
You’ve probably seen this already, but it’s really worth bearing in mind: when you’re scaling up JPGs for retina display you can safely reduce the image quality by quite a lot—to the point of getting the exact same file size as a higher quality image that’s half the size.

Grid Calculator
A handy tool for calculating grid and gutter widths although you'll still have to some calculating to get the figures to work in percentages (assuming you're designing for the Web).
