In case you want to display search result in columns, it will require adding a small piece of CSS code. Here are all of the necessary steps:
1. Login to your Admin Panel
2. Navigate to Left Menu -> Appearance -> Customize
3. Open ‘Additional CSS’ section
4. Insert the following code:
@media screen and (min-width: 800px) {
#main-content article {
float:left;
width: 30%;
margin-right:2%;
clear: none;
}
}
it will group search results in 3 columns (screenshot above).
5. Save changes by clicking on ‘Publish’ button
