How to adjust CSS on Venetian theme homepage

Thanks for your question about removing the semi-opaque triangles from the Venetian theme homepage.  This has been asked before.  You will need to go into the Customizer, click on Advanced, then Custom JS & CSS, add the code from the previous answer:

You should be able to remove the triangles by setting the before and after pseudo-selectors on the body with CSS using the WordPress Customizer’s Custom CSS tool.

This CSS snippet should take care of that:

.custom-background::before, .custom-background::after{border:0}

I hope that helps to answer your question! If you require further assistance please let us know!
