All solutions

I'm still not able to comprehend the side menu on mobile versions, any good resources or explanation so i can practice better? As for the project itself, i've created a version months ago with css position options, and updated it with flexbox as i've learnt further. Very helpful! Thank you!

The hover on the "claim your free trial" doesnt work for me, could be because it is a link and not a button? Thank you!

This is my first project with HTML/CSS. I would like some feedback regarding the structure/customisation of my code in both CSS/HTML and/or different approaches/techniques on it. Thank you in advance!
