How to add social media icons with phone number to the header?

Help please.
I have custom WordPress website. Website link: https://www.adchile.com/legend/
I’m trying to add social media icons with phone number to the top right hand side of the main header. How can I get them in place?

Here is my <div>

<div class="topinfo">
<strong>P:(210) 587-8855

<span style="float: right;">Follow us on</span>
<p>...</p>
<p>...</p>
<p>...</p>
<a href="mailto:">[email protected]</a>
</div>

[Moderator Note: Please post code & markup between backticks or use the code button. Your posted code may now have been permanently damaged by the forum’s parser.]

Here is my CSS
.topinfo {
float:right;
margin:20px 0 0 0;
display:block;
padding: 0 10px 10px 10px;
line-hight: 18px;
{

Thank you in advance!
