Chrome is an amazing guy. Browser by day, he loves to spend the rest of time with his cat Lulu.

Well, last week they got into an argument about who’s more troublesome - Lulu for Chrome or Chrome for the web developers? And then something really interesting happened! Lulu took up this challenge of learning CSS from Chrome.

Now it doesn’t happen everyday that a browser itself is teaching you CSS, right? So why don’t you join Lulu in her challenge? This maybe your best chance of getting better at understanding CSS!
