Insert buttons to share posts in Wordpress

There are some plugins that do this in a simple way. I do not know exactly what social networks you want to share, but based on what you said, I can name a few plugins with a larger number of users.

• AddToAny Share Buttons
• Simple Share Buttons Adder
• ShareThis: Free Sharing Buttons and Tools

Anything, you can find some more plugins in this listing .

Another possibility is to use the sharing button scheme provided by JetPack (if you already use it).

Hello, I already used plugins for this but the best solution I found was to do it in the hand, it is lighter and simpler to customize. $ GLOBALS ['url']="url of your template";

<div id="compartilhamento">
                        <ul>
                            <li>
