Story Map pop-up windows

[HannahHutchins3]

I am currently working on a Story Map Series and have popup windows that just display photos - no other attribute information. I would like to have a larger pop-up display of just the photo but am having a hard time finding some HTML or basic coding that will allow me to adjust the size. I don't have the ability (or knowledge) in downloading and custom coding the Story Map and I know that limits me, but I thought I would reach out to see if anyone knew some tips or tricks. 

Thanks!

Hi Hannah, did you ever get this resolved?

Hannah, I found the css for the popup windows for the story map are embedded in the esri.css.

.esriPopup .contentPane{position:relative;padding:0 15px;max-height:600px;

I had to download the css, change the attribute and link it to the index.

I'm not sure of a way to do it without download the app code and changing it.
