However, as you can see, it does not achieve the effect of an actual shadow, but it looks rather like a glow, which is not what I want. See, a shadow is the result of blocked light; it wouldn't make sense to make a shadow lighter than its surroundings.
However, the background is too light to be dark.
Is there a solution to this?
Not sure if this is super helpful, but I'm a web developer, so this is CSS and HTML.
