Custom css for vector image - only background-color works #wixstudio

Tried to modify the css of a specific vector image within wix studio.
I’ve created a custom Class and was able to change the background color. However, I cannot control any other properties like fill color, stroke.
This is what I’ve tried so far:
.customVector {
stroke: blue;
stroke-width: 10%;
fill:aquamarine;
color:blue;
background-color: blueviolet;
fill-opacity: 1;
color: blue;

}

thanks,
Guy
