Local Weather App - with Geolocation, OWM api and crossorigin

Dear coders, I just finished Local weather App. hope you guys have time to review it and your valuable feedback much appreciated. I use geolocation method (I have commented out the API method in case you like to try it as well). Also the gradient background color is changeable to weather condition. I also use the bootstrap v4 to get a good exercise and to grasp more knowledge on css. It was challenging but also enjoyed to develop it. in the future i will add wind direction and 5 days forecast. meantime i will move to next project. please do not hesitate to advice me on any coding performance and it could be a better way of coding…Thank you in advance for your time.

PS: please allow access to your location to make it work. if it is still no location check the link has https://
