Site Review – Display in Columns

Hi

I’m currently using 3 columns in version 4.7. I have read a recent reply to columns however after upgrading to the latest version and applying some of the new code, I’m still not having any success.

Below is the CSS I’m using. Any suggestions would be much appreciated.

Thanks

/* =site reviews – put in 3 columns */
.glsr-review:nth-of-type(3n+1) {
clear: both;
}
.glsr-default .glsr-review {
margin-bottom: 48px;
width: 33%;
float: left;
padding: 15px;
box-sizing: border-box;}

}

.glsr-review-author::before {
display: none !important;
}

.reviewsummary {
margin-left: auto;
margin-right: auto;
}
