推荐答案
首先，关闭<h1>容器中的anchor(<a>)元素.
First thing, close the anchor (<a>) element in your <h1> container.
无效的HTML
<h1>
<a href="http://www.monroecollege.edu:">
<img src="monroelogo.jpg" alt="" height="115" width="700"/>
<!-- missing closing </a> tag here -->
</h1>
有效的HTML
<h1>
<a href="http://www.monroecollege.edu:">
<img src="monroelogo.jpg" alt="" height="115" width="700"/>
</a>
</h1>
确保始终将结束标记添加到非无效(非自我关闭)元素中.检查每个元素的说明，以确定标签遗漏" "要求.
Make sure to always add closing tags to non-void (non-self-closing) elements. Check the description for each element to determine the "tag omission" requirement.
无效元素也称为自闭合，空和单个.这是 HTML中所有无效元素的列表 >
Void elements are also known as self-closing, empty and singleton. Here is a list of all void elements in HTML
area, base, br, col, embed, hr, img, input, keygen, link, meta, param, source, track, wbr
所有其他元素都需要一个结束标记.
All other elements require a closing tag.
此外，对于void元素，不再需要尾部斜杠了.可以接受，但不是必须的.
Also, for void elements, the trailing slash isn't necessary anymore. It's acceptable, but not necessary.
这是有效的HTML:
<br>, <hr>, <img>, <input>, <meta>, etc.
实际上，删除斜杠是 Google HTML/CSS样式指南推荐和堆栈溢出社区.
In fact, removing the slash is recommended by the Google HTML/CSS Style Guide and the Stack Overflow community.
此外，将图像放入标题元素(在这种情况下为<h1>)完全有效.这是否正确是另一个问题.
Also, putting an image inside a heading element (in this case <h1>) is perfectly valid. Whether or not it's the right thing to do is another question.
