Hi again,
For 4 columns you can use this code instead:
.search-results article {
margin-right: 2%;
border: 1px solid #eaeaea;
padding: 20px;
margin-top: 0 !important;
margin-bottom: 20px !important;
width: 23%;
float: left
}
.search-results article:nth-child(4n + 1) {
clear: both;
}
As you see this requires custom coding and the code provided above serves as a guide only and is to help you in getting started so further customization from here would be getting into custom development, which is outside the scope of support we can offer. If you need more in depth changes, you may wish to consult with a developer.
Thanks you for understanding!
