Move picture using pixels

Hi!

I have been struggling for a while with placing the social media icons on the exact position.

Here is my site: https://www.rclifeon.se/

Basically, I have this code <?php echo DISPLAY_ULTIMATE_PLUS(); ?>, that displays the social media icons, and I want these icons to display a little bit futher up on the page. Can I somehow use pixels to make sure I get the perfect positioning of the icons? I’m think something like this:

<?php echo DISPLAY_ULTIMATE_PLUS(); ?>
text-align-up: 2;

As you probably can see I don’t know much about this, but I would appreciate some help very much!

Thank you
