Hello my friends.

🔥 Picks From The Tech World

1. What I Wish I Knew About CSS When Starting Out As A Frontender​

Have a hard time understanding CSS? In this article, you will learn about three key CSS concepts that are vital to building a solid mental model of how things work.

These concepts:

• The Box Model (e.g. box-sizing, height, width, margin, padding)
• Layout (e.g. display)
• Document Flow and Positioning (e.g. position, top, left, etc.)

Well written and well explained. Recommend.

Moving on.

2. JetBrains Marketplace — Web Performance Rework​

A story of how JetBrains Marketplace team rewrote their app to SPA and reduced the bundle size by 65% + reduced development compile time by 80%.

I recommend it to anyone who wants to rewrite or optimize the speed of their application. Folks from JetBrains have shared a lot of great practices, tips and resources.

3. How do Chrome extensions impact browser performance?​

This report investigates how 1000 of the most popular Chrome extensions impact browser performance and end-user experience.

TL;DR:

• Popular extensions like Honey, Evernote Web Clipper, and Avira Browser Safety can have a significant negative impact on website speed
• On ad-heavy websites, ad blockers and privacy tools can greatly improve performance (who thought otherwise?)
