I looked around the current solutions, and this question has been partially covered in these two posts; Making Adsense Responsive and In javascript 'If mobile phone'
I have a site that is responsive and the only thing that breaks it on mobile phones is the horizontal Google Ad on my page, which makes it stick out at first with extra space since it's bigger than everything else.
I'm looking to see if anyone has a workable solution so I can basically switch between this big banner, and a smaller format for mobile browsers where the screen size is smaller and doesn't break my responsive site.
My current solution would be to pull in the screen size and show a smaller ad if it is below a certain threshold. Is there a better way?
