我正在自学如何为网站创建 php 页眉，当我尝试在谷歌浏览器中预览它时，我看不到我的页眉、导航或页脚。由于我是新手，我不确定我是否遗漏了我的编码中明显重要的东西或一些简单的东西。有人可以看看我的新 php 编码并告诉我是否做错了吗？下面列出的索引和标题代码。
我的标题代码是：
<!--==============================header=================================-->
<div id="header">
<div class="inner">
<div class="meta-info">
<div class="extra-wrap">
<ul class="social-links">
<li><a href="index.html">English</a></li>
<li><a href="esp-index.html">Español</a></li>
<li><a href="contactus.html">Contact Us</a></li>
</ul>
<form id="main-search" action="search.php" >
<input type="text" name="search" style="background-color:#CCCCCC" >
<a class="search-submit" onClick="document.getElementById('main-search').submit()" ></a>
</form>
</div>
<br><br><br><a href="supportus.html" class="button3">Donate</a> <a href="apply.html" class="button4">Apply</a> </div>
<a class="logo" href="index.html"></a> </div>
</div>
----------结束头代码
我的索引代码是：
