I've designed a box with a fading background effect. However, I am encountering an odd black border on the right side that I cannot seem to resolve. (The intentional absence of the left border may be causing this issue.)
#fadebox
{
width: 300px;
background-image: linear-gradient(to right, rgba(0,0,0,0.7), rgba(0, 0, 0, 0));
border-width: 3px;
border-style: solid;
border-image: linear-gradient(to right, #055100, rgba(0, 0, 0, 0)) 1 0 1 0 round;
}
