I’m not following… I made the portfolio item but I don’t see how to put that on my page?

Guess I spoke too soon… All the columns that are just “spacers” so I can move the text to the right or left side of the picture, are showing little white lines with that code.

That didn’t seem to add anything for me.. However when I added:

h1.av-special-heading-tag {
background: rgba(255,255,255,0.75);
padding: 10px;
}

With the custom tag, it gave me the box, but only behind the actual heading and not the sub-heading. Anyway to get that too?
