我在这里有相当令人费解的事业。
我正在建造一个用作“手电筒/探照灯”的鼠标。如果发生悬停，所有文本（内联元素，按钮，你明白这一点）都会从通常的白色反转为黑色，正常的背景是黄色的氛围。
我目前有以下设置：
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%不能正确处理半好的堆叠 div。像素剧！图像澄清：
问题：如何在保留当前对文本的效果的同时，删除由相同大小的这两个元素堆叠创建的黑色边框？
