I'am using the new Responsive Ad-Block from Google AdSense.
It works very good, but if i resize the window they do not get resized.
Is there any option or possibility to resize or reload the ads? I use media-querys for my Website Layout.
It is not possible (yet). But rotating the screens on mobiles and tablets does resize the ad (if the available space changes by rotating).
The question is: Why you want this feature? Is it to test different screensizes? Solution is to resize the screen and refresh by hand.
The end-user will not resize the window that often, so you will always serve the correct size ad when using the reponsive code from adsense.
