Hi there,
This should work for shadow:
.page-id-4030 .featured-image {
-webkit-box-shadow: 10px 10px 5px 0px rgba(0,0,0,0.75);
-moz-box-shadow: 10px 10px 5px 0px rgba(0,0,0,0.75);
box-shadow: 10px 10px 5px 0px rgba(0,0,0,0.75);
}
As for showing author and updated date on this page only, it’s do-able using PHP but I don’t think it’s worth it as it’s only for this one page.
Would you consider manually adding those in at the start of the content? It’s the easier and better solution in my opinion.
We can use CSS to make it look right.
Let me know 🙂
