How to align the page center content?

You want to align the Iframe (refers to a form of payment Yandex.money). Already tried all that I know... the text-align in CSS align on the element, making the element block, added ? to no avail.
<iframe src="https://clck.ru/GMH5t" 
 width="100%" height="222" 
 frameborder="0" 
 allowtransparency="true" 
scrolling="no">
</iframe>
