How to create five columns?

You can try something like this.

<div class="row">
    <div class="col-md-2 col-md-offset-1"></div>
    <div class="col-md-2"></div>
    <div class="col-md-2"></div>
    <div class="col-md-2"></div>
    <div class="col-md-2"></div>
</div>

This will leave 1 col space on the sides.

Does the 5 cols need to take the full container width?

OK found a better solution. Add this to your _layout.scss

.col-md-2-4 {
  @include make-md-column(2.4);
}

Then create your col as follows:

<div class="row">
    <div class="col-md-2-4"></div>
    <div class="col-md-2-4"></div>
    <div class="col-md-2-4"></div>
    <div class="col-md-2-4"></div>
    <div class="col-md-2-4"></div>
</div>

This will take the whole container width and same-width columns.

I've created a 5col panels layout here: https://github.com/arshad/radix_layouts_custom/tree/master/plugins/layou...
