I have a ul List that contain some li elements and I float them to left. It currently looks like below;

| A | B | C | D | E < space empty>|

I want it to be

| A | B | C | D | E |

that is center on the page and contents should be centered too

<div class="profile-content">
    <ul class="content-btn">
