使用HTML构建圣诞树主要依靠`
标签或嵌套`形成树形结构，通过CSS添加绿色背景、装饰色块和阴影效果，最后用JavaScript实现灯光闪烁等动态交互，可在网页直接渲染节日效果。

<h2>制作步骤详解</h2>
<div class="step">
<h3>1. 创建基本HTML结构</h3>
<p>首先设置容器和多个div元素来构建圣诞树的层次结构：</p>
<div class="code-block">
<code><div class="tree-container">
<div class="tree">
<div class="tree-layer"></div>
<div class="tree-layer"></div>
<div class="tree-layer"></div>
<div class="tree-layer"></div>
<div class="tree-layer"></div>
<div class="trunk"></div>
</div>
</div></code>
</div>
</div>
<div class="step">
<h3>2. 使用CSS创建树层</h3>
<p>利用CSS border属性创建三角形树层：</p>
<div class="code-block">
<code>.tree-layer {
position: absolute;
border-left: 75px solid transparent;
border-right: 75px solid transparent;
border-bottom: 50px solid #0a5f20;
bottom: 0;
left: 0;
}</code>
</div>
<p class="tip">通过调整border尺寸和颜色创建不同大小的树层</p>
