Hi - I desperately need some help making the 'Bespoke Digital Strategy for Visionary Brands & Artists' GIF bigger on mobile please? It looks great on desktop - but it's so small on mobile.

Can someone help please?

My deadline for this site is today and I've been stuck on this for a couple of days!

Thanks so much 🙂

Do you use Personal Plan or higher?

If you use Business Plan, we can give the code to you replace with new gif on mobile only.

Or we can give the code to replace gif with jQuery effect, thus you can adjust size on mobile.
