SiteOrigin Image widget and text wrapping

This code snippet comes from the page source. It stems from the use of SiteOrigin Image widget.
I have attempted to customize RowId, RowClass, CellClass, and WidgetClass to force the image to float, but
no CSS style customization affects div with id=”panel-10-0-0-0″. If I manually enter style=”float: left;” on
this line when INSPECTING the page, the text wraps around the image.
Is there an easy customization method to adjust this DIV?
Will some CSS file have to be adjusted? If this is the case, can you give me some guidance?
Thank you.

How can I add ‘float: left’?—->
