Code for Background

I am having trouble getting the CSS code to work in changing my background theme. I feel there may be an issue with the code (I am very new to this)

/* Place your CSS here */


stripes : [
{
color: '#bfbac2',
rotation: 335,
opacity: 50,
mode: 'normal',
width: 3,
gap: 98,
offset: 123
},
{
color: '#bfbac2',
rotation: 25,
opacity: 50,
mode: 'normal',
width: 3,
gap: 98,
offset: 123
},
{
color: '#f37721',
rotation: 25,
opacity: 60,
mode: 'normal',
width: 100,
gap: 100,
offset: 156
},
{
color: '#ed2525',
rotation: 335,
opacity: 60,
mode: 'normal',
width: 100,
gap: 100,
offset: 156
}
],
background-color : '#008060'
