如何使 CSS Slider 自动播放

Question

我有这个只有 2 张幻灯片的简单 HTML/CSS 滑块。 我需要让它每 7 秒自动播放一次幻灯片。 我不熟悉 jquery 或 javascript，所以我更容易实现 css 解决方案...

你能帮忙吗？

要处理时间，您必须使用 javascript/jquery。

您可以通过使用类名访问幻灯片，每 7 秒添加/隐藏元素，并将它们与 setInterval 函数一起使用。

var interval = setInterval(function () {document.getElementById('previous-control').addClass('hide'); document.getElementById('next-control').addClass('show'); }, 7000);

您必须在 css 中添加隐藏和显示类，并使用 display none 和 block
