Div Block is not visible!

Hi there!
I`ve created a div block with an image. It is called “greek symbol”. It looks quite fine, but if I switch to the preview mode it is not visible! :frowning: I have no clue how to fix this. May you help me? Thank you so much!!

No way to answer. Add read-only-link (And live URL)

Ok sorry. This is my first time in this forum. :slight_smile:
