Quotes Collection plugin bug

First of all, let me congratulate you for such a greate theme.

I’m using Quotes Collection plugin that doesn’t work as expected in your theme. It is included as a widget in the header of the website. When my blog is displayed on a desktop, it works out perfectly, since the quote’s text is shown on the header image. If the blog is displayed on mobile (less than 768 px), it doesn’t work as it should: the text should be displayed below the header’s image, in it’s proper div. I mean, it doesn’t make sense when the size is so limited to have the text (or whatever the widget used) displayed over the header image.

Any idea how I can change this behaviour? Maybe ith child theme CSS?
