I've had the honor to publish a guest post on CSS-Tricks, one of my favourite blogs. This blog has always been on my read list, and has helped solve tricky web problems many times. My post there is tailored for web coders. It shows how to improve your CSS code by using a technique called Critical CSS. It really speeds up the page load time on websites.
Without further ado, if you are a web developer and you are not taking advantage of Critical CSS yet, check out the post here: https://css-tricks.com/annotating-critical-css/ leave your comments there, I'll reply em all!
