Can I add a social links menu to a theme (either via CSS or something else) that doesn't normally allow for one?

Hi Sal, You can add social links to any site using a plugin. I use the Simple Social Icons plugin on nearly all my sites. Simple Social Icons is an easy way to display and customize icon links to all your various social profiles. Once you install and activate the plugin, you'll find a new widget, which you can add to any widget area on your site. You choose which profiles to link to, and then you can customize the color and size of the icons, as well as align them to the left, center, or right, all within the widget... no settings page necessary. Hope this helps!
