There are plenty of WordPress plugins out there that will quickly and easily add social media share buttons to WordPress posts. However, that ease-of-use comes with a price: those plugins frequently include far more functionality than you need. Since they’re typically designed to handle every conceivable social media platform, they include a lot more code, images, and web fonts than you need, if all you’re doing is adding Facebook, Twitter, and LinkedIn share buttons to your posts.

Woocommerce has kindly provided a Codex snippet to add social media icons to the Storefront theme. Their approach creates a very nice-looking social media icon menu; however, on displays less than 768 pixels in width, the Storefront theme hides the secondary navigation menu location used. Mobile devices using smaller displays end up with no social media icons. The Storefront theme is a responsive theme, so it really should have the capability to display social media icons at all resolutions.
