much about site coding. refer to the like button plugin url here . in this url all you have to do is
enter the parameters like "URL to Like" "width" and others at first and hit get code button
to get the code to be placed in your site as html codes -
here i show a sample codes of iframe implementation, likewise you can use other type of codes -
<iframe src="//www.facebook.com/plugins/like.php?href=http://www.programminghelp24.com/&width&layout=standard&action=like&show_faces=true&share=true&height=80" scrolling="no" frameborder="0" style="border:none; overflow:hidden; height:80px;" allowTransparency="true"></iframe>
look for the parameters in the code, you can re-enter parameters value according to your needs
and hit get code button for the right code.Copy and paste this code in your site html codes to show
like button to your valuable users and afterwards get likes from them when they clicks it.
