Image 'float:right' in Map Journal

[VarvaraTumasyeva1]

Hi all,

I am working on a storymap with each section telling about one company. And I need to add a logo to it, floating in the upper right corner.

The result should be smth like this:

I tried both css and html, 'float:right' tag works everywhere except Esri Map Journal.

Has anyone run across this? Any workaround ideas?..

I would appreciate any help! 

P.S. I use Map Journal, tested both in ArcGIS Online and Portal 10.6
