When it's getting clicked it has the default weird border around it, How to remove it?

When it's getting clicked it has the default weird border around it, How to remove it? I am using Bootstrap, I tried inspecting and seeing why the border just won't go

I was able to remove the border which is there when its not clicked or anything, but when it's clicked there is the outline/border. I don't know how it can be removed
