SharePoint 2013 Display promoted links on multiple rows - script

Every item has a default of 160px, so when you want to show rows of 3 items, just limit the space to 3*160 = 480px.
Simply add a content editor or script editor to the page and add this code:

<style>

/*display rows of 3 items*/

.ms-promlink-body {

      width: 480px;

}

</style>

If you also have buttons on top (when you have more items in the row than can be shown on the page), you can add this part to the script to remove those buttons:

<style>

/*hide the arrows when you have more items than viewable*/

.ms-promlink-header{

display:none;

}

</style>
