Need help with a gradient code i`m using!

Hey - trying to put a gradient on my top sections on mostly all pages - but its targeting my footer as well - i`m using this code

.page-section:nth-child(1){background: linear-gradient(30deg, turquoise, blue)!important;}
.page-section:nth-child(1) .section-background{background-color:transparent!important}

#page {
.page-section:nth-child(1){background: linear-gradient(30deg, turquoise, blue)!important;}
.page-section:nth-child(1) .section-background{background-color:transparent!important}
}
