All solutions

Practiced css grid with this challenge - this was also the most difficult part, but I think I managed it fine - I'd be happy if some of you would provide me some tips regarding css grid

Wanted to deepen my understanding for flex layouts and jquery.

The most challenging part was understanding the tree traversal algorithms, adding new elements and applying functions to all child elements of a node.

I also tried to make it responsive by using vw instead of fixed width

Since I'm new to the field of frontend development, I'd be happy if you have any suggestions or improvement tips.

The most difficult thing was to get the logic right for the age calculator. I had to consider different days via month, switching year etc. I tested the logic manually and just hope that all critical bugs are fixed.

CSS-wise I found the most difficult to adapt my styling for different media types (desktop, tablet, mobile), but bootstrap helped there a lot.

Since this was my first (bigger) html page I struggled a bit understanding css properties like position, display and z-index. And how everything worked in conjunction, but I think it's an acceptable solution.

If you have any suggestions for improvement I am open for feedback
