Hi there,
you can’t move the inset shadow as it sticks to the elements box model.
What you can do is layer multiple shadows though, using the one in front to mask your some of the one behind:
.entry-content a {
box-shadow: inset 0 -0.15em #fff, inset 0 -0.5em #16aa6f;
transition: box-shadow 0.2s ease-in;
}
.entry-content a:hover {
box-shadow: inset 0 -0.15em #fff, inset 0 -1em #16aa6f;
}
So our first shadow which doesn’t change on hover ie. inset 0 -0.15em #fff,
will display a white background ( change that to match your background color ) in front of the shadow you want to see.
