I have successfully rearranged the product detail page with the following changes to the catalog_product_view.xml (in our custom theme)
<move element="product.info.main" destination="content" after="product.view.additional"/>
<move element="product.info.overview" destination="content" before="product.info.details"/>
<referenceContainer name="main.content" htmlTag="main" htmlClass="page-main-full-width" />
The problem is that the product.info.main is offset to the right. I think this is done as the image area normally holds it over. Can someone please point me in the direction to remove this offset/indent?
