Hey there,
Here's some things I'd do differently.
1. Make the map full-width and put the "Latitude and Longitude" on top
of it. That would make it way easier to figure out where you are on the
map and find the place you're looking for.
2. Why can't I drag the map? Is that just not supported by OSM, or did
you for whatever reason disable that feature? Either way, seems
super-counter-intuitive for me.
3. Just show the map on pageload, not just when I enter an adress.
There's no reason to put in an extra step like this in the process.
Let's make it as streamlined as possible.
Other than that, great work.
Best, max.
