You can redefine the css for the su-post class:
.su-posts-default-loop .su-post {
margin-bottom: 2.5em;
line-height: 1.5;
display: inline-block;
width: 45%;
vertical-align: top;
margin-right: 2%;
margin-left: 2%;
}
If you’re using a responsive theme, you’d want to set the width to auto or 100% at a corresponding break point.
The first parameter field is Template, and you’d want to use the “teaser-loop” template. You can click it from the list below the field to select it.
You can also define your own templates and place them in your theme. You would then use the relative location of “my-templates/my-image-post-loop.php” in the template field.
