Clear CSS basics

Liked the layout and spacing examples. I just wish there were a few more practice items at the end of each lesson.

Really easy to follow, especially the parts on responsive pages and clean styling. A bit more depth on browser quirks would've been nice, but it was still useful.

Spacing finally clicked

The box model and margin vs. padding were explained in a way that actually stuck. The small real-world scenarios made it easy to apply right away.

Practical and calm

I especially liked the lesson on building responsive layouts with CSS, because it showed how to adjust spacing and alignment without getting messy. The concrete examples made it feel very doable.
