Centering a button

Can someone help me out on how to center a single button in a page block.

Here is the code below.

<a class="bx-btn" href="/search.php?search_result_mode=ext">Search People</a>
<div class="clearfix"></div>

You need to override dolphins CSS for the bx-btn class.

This code will do it. Placed in a text block.

<style>
.bx-btn {
    float: initial !important;
    display: inline-block !important;
    line-height: 52px !important;
}
</style>
<div style="text-align: center;"> <a class="bx-btn" href="/search.php?search_result_mode=ext">Search People</a> </div>
