On [this page](http://wowballoons.com/home.html), in the TESTIMONIALS section below the fold on the right, the content of the testimonial (the text in the `<article>` tag has a border:

```
.testimonial-entry.dark {
    background-color: #F6F6F5;
    border: 1px solid #D9D9D9;
}

```

Google Chrome's Developer Tools Computed Style viewer confirms that there really is a right border, that it's not being overwritten or anything:

```
border-right-color: rgb(217, 217, 217);
border-right-style: solid;
border-right-width: 1.1111111405455043px;

```

Nevertheless, the right border is not visible. Could anyone explain why?
