Css embedded in head section works in edit mode but not in regular site

[robinprice]

I added this to the head section of my page's code editor. The change is reflected when I'm editing the page but when I go to the public version it overrides my css with the background colour set with the regular slider.

Pls help

body {
background: linear-gradient(#dcd6ff, #b3ffeb) !important;
}
