Menu View buttons vertical

I have seen a few subjects on this but none of the suggestions seem to help.

I have a menu view with several buttons on it and I would like to show the buttons one under the other rather than across the page.

I had tried in CSS, as was suggested on another page

#view_322 .content {
float:left;
}

but did not seem to do anything.

Awesome.  Thank you. Worked perfectly.
