Is there anyway to place the social icons (the ones controlled from t he customizer) within the content and sidebar? also inside the footer widgets. Please let me know
Unfortunately, there is no option to automatically include the social icons to the content area or sidebar of your site.
However, you can use Font Awesome code to include these icons wherever you like be it a text widget or in a post/page. Below is an example snippet to add the Facebook icon.
<i class="fa fa-facebook"></i>
If you wish to add the icons to a widget, you will want to add these code to a Text Widget. For more information and examples of all the icons, see the Font Awesome website which I have linked below.
