I can not adjust the position of the main background for my webpage. The website is robotdukkani.com. I wanted to move the main blue background to 100px left, so here is my css. but, whatever value I write to top or left, it does not move the position of the blue background. How can I make the main blue background to start where I want?
and... here is the html on my index page.
<img src="pictures/mainbackgr.jpg" width="100%" height="100%">
