There are many ways to add social icons or other icons as links in your website’s navigation bar. You can do so on any website relatively easily using Font Awesome or other icon font libraries and tool sets. Scroll to the bottom of this post for a list of resources related to icon fonts, including Font Awesome resources and guidance.
If you do not know about Divi, click one of the links above to learn more.
Let’s get to work. We are going to make something like this:
Log into your website and go to your Menus page in the admin (Appearance>Menus).
At the top right of the page look for “Screen Options”. Click the words to pull down the screen options for the Menus page.
Tick the boxes for Link Target, Title Attribute and CSS Classes. You only NEED the CSS Classes but I will show you options for using the others. Then click “Screen Options” to push the menu backup and away.
Select the menu you want to add your links to. If you want to create a top bar menu and do not have one yet, you can reference this page with steps. Then tick the box next to Secondary Menu under Menu Settings at the bottom of the Menu page and Save.
Adding a New Navigation Menu Link
Now on the left side of the page click on “Custom Links” as that is how we are going to add our links.
Adding Facebook icon
Now you want to enter the following into the “Link Text” field: 
If you want another Divi Icon Font, go to this page and scroll down to below where it says, “Complete Set and Unicode Reference Guide” and look for the code under the icon you want. For example here is the Facebook icon code:
Now click the “Add to Menu” button.
Then go to your new link and click to open it to show its settings. The Navigation Label may look different, like in the image below, that is fine. In the CSS Classes you want to add: et-pb-icon. This is the class the Divi theme uses for its icon fonts but really the only style needed it to assign the font family as ETmodules. So if you prefer you can use your own CSS class and assign that font family to it. That will convert the Navigation Label to the icon you want to see.
Optionally you may want to have your link open in a new window when a user clicks it. If you do, click this box.
And for Title Attribute you can put some words indicating what will happen when a user clicks the link. This will show up to your user if they hover over the icon with their cursor. It also helps you know when looking at this custom link in the admin where it goes.
That is it. Save your menu. You just created your Facebook icon as a link to your Facebook page.
You can style it in two ways. The first is by going to the Theme Customizer and editing the styles for the navigation menu you added it to.
Troubleshooting Tip: For me when I first added the icons to the menu, for some reason the icons were huge. I change the font size from what it was showing as 12 pixels to 13 pixels and then back to 12 and it fixed it.
You can also use CSS to assign new styles. To do this you can add another unique css rule to the CSS Classes and then apply your styles to it, changing it’s color, positioning or size for example to a unique color, positioning or size for that icon.
Adding your Twitter icon
And you can create your Twitter icon the same way using the code for Twitter on this page and looking below “Complete Set and Unicode Reference Guide”.
Adding a Telephone link
You can easily add links for your telephone number and email address if you want. If you put tel: before the number as in the image below, it should become a link that can be clicked on a smart phone to call.
For an email address you use the format mailto:firstname.lastname@example.org. And for the Link Text you can display your phone number or an icon for a phone – or email as you like.
