Weird dropdown behavior css - html

Question

I have two dropdown lists and they work as expected(that they show the content on hover) however, If I click on the area outside (left side) the list , the dropdown list still shows.
I have tried fixing the CSS but I have not been able to pin point the problem.
Is there a better approach for styling dropdown as I am still new to CSS.
UPDATE:
Testing this in firefox and I was unable to recreate the issue. How can I make sure that works consistently in all browsers?

Here - I shortened the example down a bit (I also don't think you need all that separate CSS for more than one button, you should be able to utilize the classes, and just change specifics by using #dropdown_two .classname for the things (like position) you might want to change.
The problem in Chrome, I think, was that the width of the container was wider than the button itself, and that made it misbehave. It might not be 100%, but it should get you started. I changed some values to dynamic (em instead of px) so there might be some issues.
#dropdown-one {
margin-left: 20em;
}
.dropbtn {
