Guillermo77 on "[Theme: GeneratePress] About functions after post like button facebook"

Hi tom, just one question if you or any can help me, I don't know about wordpress function.

I want add the code of like facebook button after the post, and if is possible after the plugin "share buttons adder"- (if can also before post)
For exp:

function share_this($content){
    if(!is_feed() && !is_home()) {
        $content .= '<div class="share-this">
                    <div class="fb-like" data-layout="button_count" data-action="like" data-size="large" data-show-faces="false" data-share="false"></div>
                </div>';
    }
    retu $content;
}
add_action('the_content', 'share_this');

Because plugins use iframe version no responsive.-
