Custom Post Archive Layout

Hello,

I am using Custom Post Types for the first time (via the Custom Post Type UI plugin), and would like to create a grid-style archive page for this CPT (called “Properties”).

The “Properties” CPT archive page works fine, but I am having trouble styling it. I did eventually find an easy solution for a grid layout, but the css only applies to regular category archives (see here), not to custom post archives (see here). The css is as following:

.archive .post, .blog .post {
display:inline-block;
vertical-align:top;
width:45%;
padding:1.25%;
margin:1.25%;
min-height:170px;
background-color:#eee;
}

Does anybody perhaps know how I could get this css to apply to CPT archive pages too? Have been trying to target “.post-type-archive-properties” in css, but have been unable to solve my problem so far.

Regards,

Jason
