@Daniel you could increase the width to around 45% and that would make them appear centered. You can find the code around line 722 in your css –
.plans .first,
.plans .second,
.plans .third {
background-color: #fff;
border: 1px solid #ddd;
float: left;
margin: 20px 2%;
padding: 40px 10px;
width: 45%;
}
BTW, I used to live in Nashville. I recognized the “Batman Building” in the pics. Great photos! Did you take these pics?
