在本文中，我们将使用 HTML 和 CSS 在锁屏出现之前创建一个窗口加载效果。
Windows 加载效果概览： 
方法：
- 创建一个包含 HTML div的 HTML 文件，我们在其中提供加载器效果。
- 然后我们创建 5 个 span 元素，用于创建内联元素。
- 然后我们必须使用@keyframe 来创建动画功能。
- 然后我们必须使用 nth-child() 属性来选择不同的孩子。
HTML代码：
- 首先，我们创建一个 HTML 文件 (index.html)。
- 现在在创建我们的 HTML 文件之后，我们将使用
标签为我们的网页提供一个标题。它应该放在 <head> 标签之间。</li> <li>我们将提供所有动画效果的 CSS 文件链接到我们的 HTML。这也位于 <head> 标记之间。</li> <li>现在我们添加一个来自 Google Fonts 的链接，以便在我们的项目中使用不同类型的字体系列。</li> <li>来到我们 HTML 代码的正文部分。</li> <li>然后，我们必须创建一个 div，我们可以在其中存储所有标题部分和 span 标签。</li> </ul> <div class="noIdeBtnDiv"> <div> <h5 class="code">index.html</h5> <div class="hcb_wrap"> <pre class="prism line-numbers lang-kotlin" data-lang="kotlin"><code class="replace"><!DOCTYPE html> <html lang="en"> <head> <link rel="stylesheet" href="style.css"> <link rel="preconnect" href="https://fonts.gstatic.com"> <link href= "https://fonts.googleapis.com/css2?family=Dosis:wght@300&family=Hanalei&display=swap" rel="stylesheet"> </head> <body> <h1>Windows-Loading-Effect</h1> <div class="container"> <span></span> <span></span> <span></span> <span></span> <span></span> </div> </body> </html></code></pre> </div> <p></p> <hr/> <h5 class="code">style.css</h5> <div class="hcb_wrap"> <pre class="prism line-numbers lang-css" data-lang="CSS"><code class="replace">*{ margin: 0;
