I'm having some problems using Susy responsive grids. I'm trying to set up a two row, three column layout. Here is the code I'm using.

```
$susy: (
columns: 12,
gutters: 1/2,
math: fluid,
output: float,
gutter-position: inside,
);

$desktop:960px;

@include breakpoint($desktop){
body{
    @include container(95%);
    background: $faintgray;
}

.container {
position: absolute;
top: 50%;
-webkit-transform: translateY(-50%);
-ms-transform: translateY(-50%);
transform: translateY(-50%);
}

h2 {
    margin: 0 auto 13px auto
}

section {
    @include span(4);   
    text-align: center;
}

section:not(:first-of-type) {
    border-left: 1px dashed $lightgray;
}

}

```

And here is the HTML:

```
<div class="container">
<section id="frost">
    <h2>Frost Bank</h2>
    <p>Frost Bank founded in 1868 is based in San Antonio with over 110 financial centers across the state.</p>
    <a href="#" class="myButton"><i class="fa fa-search"></i>&nbsp;View</a>
</section>

<section id="shiner">

<section id="honeysucklewhite">

    <a href="#" class="myButton"><i class="fa fa-search"></i>&nbsp;View</a>
</section>

<section id="morestuff">

    <a href="#" class="myButton"><i class="fa fa-search"></i>&nbsp;View</a>
</section>   
</div>

```

There's two problems going in here. 

Problem #1
At certain points in the browser width, the layout gets wonky and my rows are misaligned. At about 960px it's incorrect, then at 1000px it is corrent, then it happens again at 1020px, than corrects again. See photos:

Problem #2
When I add the vertical alignment to the container, The container centers vertically correctly, but the container shifts to the right about 10px so it's not centered horizontally. See photo.

Any help is greatly appreciated.
