边框半径：50% 不起作用 | CSS/HTML/JS

Question

这里的要点是将div的位置设置为鼠标作为附加效果，它应该有一个半径，但它不起作用：

let inner_circle = document.getElementById("inner_circle");

window.addEventListener("mousemove", function(mouse) {
  inner_circle.style.transform = `translate(${mouse.clientX}px, ${mouse.clientY}px)`; // sets the position of the inner circle to the mouse
});

#inner_circle{
    margin-left: -3px;
    margin-top: -3px;
    position: fixed;
    top: 0;
    left: 0;
    border: 1px solid #703be7;
    border-radius: 50%; //<- doesn't work
    font-size: 1px;
    background-color: #703be7;
    width: 6px;
    width: 6px;
    z-index: 1000001;
    pointer-events: none;
}

<div id="inner_circle"></div>

Answer 1

更改你的 CSS。宽度：6 像素；宽度：6 像素；宽度：6px；高度：6px；

let inner_circle = document.getElementById("inner_circle");

window.addEventListener("mousemove", function(mouse) {
  inner_circle.style.transform = `translate(${mouse.clientX}px, ${mouse.clientY}px)`; // sets the position of the inner circle to the mouse
});

#inner_circle{
    margin-left: -3px;
    margin-top: -3px;
    position: fixed;
    top: 0;
    left: 0;
    border: 1px solid #703be7;
    border-radius: 50%; //<- doesn't work
    font-size: 1px;
    background-color: #703be7;
    width: 6px;
    height: 6px;
    z-index: 1000001;
    pointer-events: none;
}

Answer 2

我假设你指的是这里第二行的高度，这使得它成为一个问题

#inner_circle{
width: 6px;
width: 6px;
}

所以只需将其更改为高度：

#inner_circle{
width: 6px;
height: 6px;
}
