CSS Question

Why the following website on mobile has a horizontal scroll?

I am working on the following mobile website

http://www2.myaffiliatepeople.org/JuneVersion/TAP_Default.html

I can't understand why it has an invincible horizontal scroll (you can move the website in the X axis) How can I remove it?

I was checking every section and I can't see where is the bug.

Any help will be very welcome.

Thanks
A

Answer

remove margin-left:-15px and margin-right:-15px from .row

new code :

.row {
  margin-right:0;
  margin-left:0;
}
