I am wondering if there is a way to change the shape of the advertisement sections in the “Advertisements Below Slider” widget. I want to change them from a box to a circle with the text and picture inside. I’ve been experimenting with changing them through custom css, but can’t seem to figure it out.
What you are trying to achieve will require customizing the shipped theme by creating a child theme and making the customization, which is a quite beyond the scope of the basic support.
You would need some coding skills to achieve it.
