How to align the Vkontakte "Share" button to the center in the bootstrap column?

Question

css

Hello! I inserted a button Share from a contact on the site, but it sticks to the left edge. In addition to this button, I also inserted from classmates and Facebook. The last two are perfectly centered using the 'text-center' css class. It looks something like this:

<div class="col-xs-12 col-lg-4 col-md-4 col-sm-4 text-center">

But it doesn't work for contact. The button stubbornly sticks to the left edge. Who faced, tell me, how did you solve it? Thank you.
