This post is just awesome! Although I had some issues with z-index and some elements just didn't want to show up cause of "bottom: 0;" in CodePen(Any guess why?). At least I made it in my own way of sort and I learned a hell lot out of these 3 posts.
Thank you and keep up the good work!
Not sure... if you add the link to your pen, I'd be happy to have a look
Here is the pen: "codepen.io/aggelow/pen/yxPBjW".
oh dear! that's because there's no size or position for the 'lighthouse-group' element. This is 100% my fault, I forgot this step in the tutorial (I've now amended the post). If you add the below CSS, and use the bottom property again, your issues should be fixed
