I am using an html template for my site.
URL - http://www.tekestate.com/site/easydelivery/index.php
Now I don't know what is wrong with my css because if you see it leaves a unwanted white space on the right which can be scrolled for the mobile version as well as the desktop version.
My CSS (very large to put it here) - http://www.tekestate.com/site/easydelivery/stylesheet/style.css
I looked for the solution but nothing worked as I am not able to figure out where in the problem lies.
