Can you put an animated gif as a banner?

[Walkitch]

We are redesigning our homepage, which includes changing the banner image. I was thinking of an animated gif where what's shown on the screen of a computer would change over time. Would this be possible? And are there size restrictions?

You could put a gif on the page, but depending on what you are showing, the length/size of the file, GIF may not be the best format to do this.  I would be very cautious and look at the export size of your file and determine whether visitors on mobile and desktop would both benefit from it.
