I have an image that is 1000px X 600px . I want to use it as a responsive background for a div but would like to set a minimum width of 1000px despite how small the browser
There's now an option for background-size
to only scale the image until the picture has met it actual height/width. This way, you don't have to set a min-width or anything.
In your CSS:
body {
background-size: cover;
}
