How to set up maps on the site?

Question

JavaScript

Created a test version on this site. I can’t launch the map at all, but when I press F12 (developer tools), when the modal window is open, the map immediately appears, what is the reason for this and why is the marker not centered? Thanks a lot in advance!

And why did you first declare a global map variable, and then declare the same variable locally (if you need a global variable, then when assigning a variable, discard var .
first
and then
map = new ....;
