Forget normalize or resets; lay your own CSS foundation

⚠️ This article is outdated: Global CSS is an anti-pattern; components should be individually styled using tools such as styled-components. See Fix for the most recent, though still outdated styles from this article.

Most start their front end styles by throwing in a reset such as Eric Myer’s or the more fashionable normalize.css. I will say a few nasty things about both approaches before I present to you the perfectionist alternative: Your own custom foundation.

Foundation is a good word for a different approach. Resets strip user agent default styles back. Normalizing attempts to even out the differences and fix a few things. A foundation strips and adds style

How to super optimize a favicon

⚠️ This article is outdated: For some reason the ImageMagick convert CLI no longer generates smaller .ico files when the source .png files have been optimized. After a few hours investigating I can’t workout why, or even with what versions everything worked. Here is a related StackOverflow question.

Learn how to manually create optimized website favicon.ico files as much as 60%+ smaller in file size without sacrificing content or quality.

This is something very few people seem to do, probably because no single tool exists. A pity since a favicon.ico file in the website root (still best practice) is one of the few things guaranteed to be downloaded by every first-time visitor. The smaller it is, the sooner it can appear.

The savings can be particularly juicy for icons containing multiple sizes, which is also best practice given the variety of ways favicons are used.


CSS font smoothing coming to Firefox for Mac

Finally a Mozilla equivalent to -webkit-font-smoothing: antialiased is on the way in Firefox 25: -moz-osx-font-smoothing: grayscale. No more chunky font icons in Firefox for Mac!

Unfortunately we will have to wait a few weeks for this to be useful as Firefox 25 is currently in Aurora phase; according to the rapid release schedule it will be hit Beta September 17 for an October 29 2013 release.

It’s a good idea to begin using it now, IcoMoon has stealthily adopted it already. You can always download Firefox 25 and take it for a spin first.

A guide to cache related graphql-react options.

graphql-react options guide

This is a guide to the cache related options for the useGraphQL React hook. The reloadOnLoad and resetOnLoad options also apply to the GraphQL instance method operate.


The defaults are suitable for typical query use, as apps tend to have more queries than mutations.
