Did you discover this in your workspace? If so, make a snapshot of your workspace and post the link to it here.

When you declare it in the div, make sure you do not put the dot in primary-content in there. This is how you should do it: <div class="primary-content">

The dot before the class name is only used in CSS to tell it that it's a class name.

I had this issue occur however it seemed to be a browser error and slightly my own as the border is there, it just blends with red border - due to it being 2px.

Try changing the size value to something like 20px (for testing purposes) and see if it appears.
