我在这里遇到了一个相当棘手的企业。
我正在构建一只用作“手电筒/探照灯”的鼠标。如果发生悬停事件，所有文本（内联元素、按钮等等）都会从通常的白色反转为黑色，正常的背景是黄色调。
我目前拥有以下设置：
const _$shadow = $('.b-cursor__shadow');
const _$front = $('.b-cursor__front');
const _$back = $('.b-cursor__back');
$(document).on('mousemove', (e) => {
_$back.css({
left: e.pageX,
top: e.pageY
});
_$front.css({
left: e.pageX,
top: e.pageY
});
_$shadow.css({
left: e.pageX,
top: e.pageY
});
});html,
body {
padding: 0;
margin: 0;
cursor: none;
background: red;
}
.test {
background: darkblue;
}
p {
color: white;
font-family: sans-serif;
font-size: 20px;
max-width: 30rem;
padding: 1rem;
margin: 1rem;
border: 1px solid white;
}
p,
span,
a {
position: relative;
z-index: 105;
}
.b-cursor__back,
.b-cursor__front,
.b-cursor__shadow {
position: fixed;
width: 8rem;
height: 8rem;
margin-left: -4rem;
margin-top: -4rem;
border-radius: 50%;
}
.b-cursor__shadow {
box-shadow: 0px 0px 10px 10px rgba(231, 232, 192, 1);
}
/* background changes */
.b-cursor__back {
z-index: 104;
background: #18173e;
clip-path: circle(50% at 50% 50%);
}
.b-cursor__front {
z-index: 106;
background: white;
clip-path: circle(50% at 50% 50%);
mix-blend-mode: difference;

<p>ja uh misschien werkt dit wel niet

这几乎产生了预期的结果，除了border-radius: 50%不能正确处理半透明堆叠的div。像素问题！以下是澄清的图像：
问题：如何在保留文本当前效果的同时移除由两个相同大小元素堆叠创建的黑色边框？
