How do I set the background image size in CSS?

Question

So I have css code as follows:

.jumbobg {
    background: url(\'http://znc.mane-frame.com/static/silverleaf.png\') fixed          


        

Answer 1

for multiple backgrounds in the way you are using (shorthand) here is the syntax:

background: [  , ]* 

 =  ||  [ /  ]? ||  ||  || {1,2}

 =  ||  [ /  ]? ||  ||  || {1,2} || 

so with that in mind here is an example how to set background-size for the 1st background:

body {
  background: url(http://lorempixel.com/1200/900) repeat-x scroll 0 45px / auto 100%, url(http://lorempixel.com/1200/45) no-repeat scroll center 0 / 100% auto
}
