Ok, I\'m trying to design a website that has an image at the top that spans the full width of the browser. And below that I want to put different colored div containers that
The body element has some margins by default. Unless you remove them, any element that you put inside, no matter it's width (unless it's in position absolute I think) will have some borders. They aren't borders, but the gab in between the end of your element and the side of the body. Try this :
body{
margin: 0;
}
If that doesn't work, then please show us an example of your code on JSBin, Codepen or similar (or even a live version if possible).
