Dear Richie, With the help of short coder, I have placed banner at the top. But at this moment its position is in center. I want it to be on the right hand side of the header so that it has a fair distance from my logo. You can check the present position of banner at https://www.traveliaa.com

Also, I want to add social media buttons below the posts so that people can share it. Can u suggest me best, dynamic, floating widget for social media sharing buttons below the posts and pages. Also if this widget can provide me the information that how many people have re tweeted or shared my posts, that will be reaally very helpful. May be something like it has been used in this blog..i.e, https://www.thebuzzdiary.com
