如何使用 CSS 创建自定义光标？

自定义光标增强了文档的可读性，并将用户的注意力吸引到网页的特定部分。今天我们将学习如何使用 HTML、CSS 和 Javascript 为网页创建自定义光标。

方法：

• 隐藏默认光标。
• 定义包含所有动画的类。
• 当按下鼠标按钮或移动鼠标指针时动态添加和删除这些类。

例子：

JavaScript 代码：

const cursor = document
    .querySelector(".custom-cursor");
  
// Adding the animations when the
// mouse button is clciked
  
window.addEventListener("mousedown", (event) => {
    if (!cursor.classList.contains("click")) {
        cursor.classList.add("click");
  
        setTimeout(() => {
            cursor.classList.remove("click");
        }, 800);
    }
});
  
// Getting the position of the cursor
window.addEventListener("mousemove", (event) => {
    let x = event.pageX - cursor.offsetWidth / 2,
        y = event.pageY - cursor.offsetHeight / 2;
  
    cursor.style.left = `${x}px`;
    cursor.style.top = `${y}px`;
});
