Many devs resort to Bootstrap or other frameworks when it comes to modal / pop-up windows.
But it's not needed at all. If you would like to learn how to code your own responsive flexible modals, here is my approach.
It's been a year since I last had time to make a video tutorial and I got some great feedback from this forum then.
So besides the hope that it can be helpful to many people, I would also appreciate critique, ideas for alternative approaches etc. Thanks
