Hi tonyx4xx,
I had the same problem when I started with my blog. The code rdellconsulting posted works at my page too, but only in combination with this:
.type-post, .type-page, .type-attachment {
margin: 0 0 1.5em 0;
padding: 0.8em 1.5em 1.5em;
box-shadow: 0 0 4px #ddd;
border: 1px solid #ddd;
background: #fff;
}
I don’t know why ?? Now I have white boxing at the homepage, the post and the widgets. I am not happy with the white boxing from the widgets in my footer, but I don’t know how to get rid of it and keep the boxing of the posts and the sidebar widgets bat the same time.
At my page, this looks like this: https://www.tinytraveler.de
Hope that helped! ??
