I want to use an animated gif as my featured image in WordPress (div, theme). I read a lot about the problems using animated gifs in WordPress, so I chose "large/full size" for the gif file and it works fine on a 13" screen. But on mobile devices, it doesn't resize to the smaller screen width. It stays at 1278px width and therefore gets cropped out.
How do I make the animated gif for all devices work so it keeps it's animation and still fits within the screen width?
