I tried to use a small animation (MP4) as the site title "image" and it works perfectly in Safari. So using a video instead of text or image can be a feature.
Sadly it is broken in Chrome... Maybe it's easy to fix that "bug" and can be added as a feature.
/Edit: GIF probably works, yes, but I think it will probably have a huge file size and have the usual "pixelated gif-aesthetic" and not be very smooth.
Ah cool i see your website now, Nice Cookie bar! :)
Have you had a look into this?
Could be a video formatting problem that other browsers don't work so well but changing it may create a solution?
Hope this helps :)
