在我的上一个问题取得快速成功之后，我在验证时想出了另一个。
我得到'文件类型不允许'P'在这里; ....'错误。简而言之，我正在尝试在DIV中编写文本并使用
标签来分隔段落。经过一番搜索，我发现了这个问题。当<p>在<font .....>定义内时（因为这是内联中的块），它会出错。所以我尝试使用<h6>标签代替（第57行）并在CSS中单独定义它，我认为它可以工作，因为它被称为块级元素。
理想情况下，我想要一种最初定义文本属性的方法，让它为所有段落打开等等。然后在最后关闭它。 - 而不是每次创建新的<p>时都必须重新输入。
再次 - 非常感谢任何帮助.-关于我的布局以及如何改进的建议。

答案 0 :(得分：4)
<font>被1996中的CSS取代。停止使用它。
您不能在标题中放置一个段落。
使用相应的标记。
如果要设置段落样式，请将CSS应用于<p>。
如果您想将一堆段落组合在一起，请选择<section>，例如<article>，<aside>或<div>。如果HTML没有描述分组原因的元素，则使用通用块级元素：{{1}}。
如果您不想以相同的方式设置该类型的所有元素的样式，则添加编写an appropriate element所需的任何类和ID，以定位您想要影响的元素。
答案 1 :(得分：0)
就像昆汀所说，使用font元素毫无意义。
您应该创建一个段落类，而不是：
<font face="cambria" color="black" size="5px"><p><strong>EXTRAS</strong></p>
<p>'Cool Geography'<a href="http://www.coolgeography.co.uk/GCSE/AQA/Development_Gap/Development%20Gap.htm" target="_blank">Website</a></p>
<p>BBC Bitesize <a href="http://www.bbc.co.uk/schools/gcsebitesize/geography/development/" target="_blank"><img src="images/bitesize1..png" width="35" height="25" alt="bitesize" /></a>
</p>
</font>
应该是类似的段落样式：
<p class="yourclassname">Enter paragraph text</p>
<p class="yourclassname">Enter paragraph text</p>
然后将所需的字体和样式应用于CSS中的类：
.yourclassname {
font-family: cambria;
color: black;
font-size: 5px;
}
这应该可以解决问题。
