是否有可能在每个打印页面上打印带有自定义页眉和页脚的HTML页面?
我想在每个打印页面的顶部和底部添加“UNCLASSIFIED”字样，字体为红色，Arial，大小为16pt，无论内容如何。
为了澄清，如果文档打印到5页上，那么每页都应该有自定义页眉和页脚。
有人知道使用HTML/CSS是否可行吗?

我很惊讶Chrome有这么糟糕的CSS打印支持。
我的任务要求在每页上显示稍微不同的页脚。在最简单的情况下，只是递增的章节和页码。在更复杂的情况下，页脚中有更多的文本(例如几个脚注)，这可能会扩大它的大小，导致该页内容区域的内容被缩小，部分内容回流到下一页。
CSS打印不能解决这个问题，至少在目前拙劣的浏览器支持下解决不了。但在印刷之外，CSS3可以做很多繁重的工作:
https://jsfiddle.net/b9chris/moctxd2a/29/
<div class=page>
<header></header>
<div class=content>Content</div>
<footer></footer>
</div>
SCSS:
body {
@media screen {
width: 7.5in;
margin: 0 auto;
}
}
div.page {
display: flex;
height: 10in;
flex-flow: column nowrap;
justify-content: space-between;
align-content: stretch;
}
div.content {
flex-grow: 1;
}
@media print {
@page {
size: letter; // US 8.5in x 11in
margin: .5in;
}
footer {
page-break-after: always;
}
}
There's a little more code in the example, including some Cat Ipsum; but the js in use is just there to demonstrate how much the header/footer can vary without breaking pagination. The key really is to take a column-bottom-sticking trick from CSS Flexbox and then apply it to a page of a known, fixed height - in this case, an 8.5"x11" piece of US letter-sized paper, with .5" margins leaving width: 7.5in and height: 10in exactly. Once the CSS flex container is told its exact dimensions (div.page), it's easy to get the header and footer to expand and contract the way they do in conventional typography.
例如，当脚注增加到8个而不是3个时，剩下的是页面内容的流动。在我的情况下，内容已经足够固定，我不需要担心，但我相信有办法做到这一点。首先想到的一种方法是将页眉和页脚转换为100%宽度浮动，然后用Javascript定位它们。浏览器会自动处理常规内容流的中断。

一种只适用于为每个页面添加标题的方法是将您的内容包装在<table>中，然后将您的标题内容放在<thead>标签中，并将您的内容放在<tbody>标签中，如下所示:
<table>
<thead>
<tr>
<th>This content appears on every page</th>
</tr>
</thead>
<tbody>
<tr>
<td>Put all your content here, it can span multiple pages and your header will show up at the top of each page</td>
</tr>
</tbody>
</table>
这在Chrome上是有效的，对其他浏览器不是100%确定。
试试这个，对我来说，它可以在Chrome, Firefox和Safari上运行。您将获得固定的页眉和页脚到每个页面，而不重叠的页面内容
CSS
<style>
@page {
margin: 10mm;
}
body {
font: 9pt sans-serif;
line-height: 1.3;
/* Avoid fixed header and footer to overlap page content */
margin-top: 100px;
margin-bottom: 50px;
}
#header {
position: fixed;
top: 0;
width: 100%;
height: 100px;
/* For testing */
background: yellow;
opacity: 0.5;
}
#footer {
position: fixed;
bottom: 0;
width: 100%;
height: 50px;
font-size: 6pt;
color: #777;
/* For testing */
background: red;
opacity: 0.5;
}
/* Print progressive page numbers */
.page-number:before {
/* counter-increment: page; */
content: "Pagina " counter(page);
}
</style>
HTML
<body>
<header id="header">Header</header>
<footer id="footer">footer</footer>
<div id="content">
Here your long long content...
<p style="page-break-inside: avoid;">This text will not be broken between the pages</p>
</div>
</body>

我花了大半天的时间想出了一个对我有效的解决方案，我想我可以分享我所做的。上述解决方案的问题是，我所有的段落元素都会与我想要在页面底部的页脚重叠。为了解决这个问题，我使用了以下CSS:
footer {
font-size: 9px;
color: #f00;
text-align: center;
}
@page {
size: A4;
margin: 11mm 17mm 17mm 17mm;
}
@media print {
footer {
position: fixed;
bottom: 0;
}
.content-block, p {
page-break-inside: avoid;
}
html, body {
width: 210mm;
height: 297mm;
}
}
p和content-block的page-break-inside对我来说至关重要。任何时候我在h*后面有一个p，我把它们都包装在一个div class =“content-block”>中，以确保它们保持在一起，不会破裂。
我希望有人发现这是有用的，因为它花了我大约3个小时来解决(我也是新的CSS/HTML，所以有…)
EDIT
根据评论中的请求，我添加了一个示例HTML文档。您需要将其复制到HTML文件中，打开它，然后选择打印页面。打印预览应该显示此工作。对我来说，它在Firefox和IE浏览器中都能运行，但Chrome浏览器把字体设计得小到只能在一个页面上显示，所以它在Firefox和IE浏览器中无法运行。

@Daniel在2012年对缺乏CSS3特性支持的问题做了一个评论:顶部中心和底部中心。
好吧，在Chrome 73+，下面的片段工作，其中页眉和页脚是<header></header>和<footer></footer>元素定义在页面内。
@page {
@top-center { content: element(header) }
}
@page {
@bottom-center { content: element(footer) }
}
