We are using the online editor to build our Storymap and hosting it locally.
So far everything is going smooth, we are close to releasing our first Storymap, but... we would like to add some links in the header... and maybe an overlay image on the map (icon image not layer). However, nothing I do to the locally hosted HTML nor JS files does anything to the output. I really don't want to (if it's even possible) implement jQuery in order to make what I want happen... but I will.
Is there any other route?
