Html.PropertyFor properties to render items on one row in the view

I am trying to get my blocks in my ContentAre on one row. Now they end up on one row each.

<div class="row">               
                @Html.PropertyFor(x => x.Advice, new { ChildrenCssClass = "block" })</div>

Advice is my ContentArea that holds my blocks. I have tried different properties to PropertyFor without any luck. 

Does anyone of you have any idea of how I can make this work?
