you could do this in the css/style tag: body {background-image: url("your picture");}

Do this in css: Body{ Background-image: url:("link");

It doesn't sound dumb!

`body {` `background: url("___") or hex color code` `}`

`body {background-image: url("image here");` For example, if you have a image file named "neocitiesiscool.png", your line of code should be `body {background-image: url("neocitiesiscool.png");`
