You need to master both Flexbox and CSS Grid in order to professionally build modern websites & web apps. If you haven't mastered both of them yet, I highly recommend going through my CSS Course.

Before I mastered CSS, I lost a ton of time & energy fiddling around with CSS.
So I created a CSS course to help you avoid the same mistake. Check it out here if you're interested.
