Creating page headers and footers using CSS for pr

问题:

I'm creating a PDF using Flying Saucer (which dumps out CSS/HTML to iText to a PDF) and I'm trying to use CSS3 to apply an image header and footer to each page.

I'd essentially like to put this div in the top left of each page:

<div id="pageHeader">
    <img src="..." width="250" height="25"/>
</div>

My CSS looks somewhat like this:

@page {
    size: 8.5in 11in;
    margin: 0.5in;

    @top-left {
        content: "Hello";
    }
}

Is there a way for me to put this div in the content?

回答1:

Putting an element to the top of each page:

@page {
  @top-center {
    content: element(pageHeader);
  }
}
#pageHeader{
  position: running(pageHeader);
}

See http://www.w3.org/TR/css3-gcpm/#running-elements (works in Flying Saucer)

To include both header and footer on pages (elaborating on excellent answer from @Adam):

<style>
@page {

    margin: 100px 25px;
    size: letter portrait;

    @top-left {
        content: element(pageHeader);
    }

    @bottom-left {
        content: element(pageFooter);
    }
}

#pageHeader{
    position: running(pageHeader);
}

#pageFooter{
    position: running(pageFooter);
}

</style>
<body>
    <header id="pageHeader">something from above</header>
    <footer id="pageFooter">lurking below</footer>

    <div>meaningful rambling...</div>
</body>

NOTE: In order for footer to repeat on every page it may be necessary to define it BEFORE other body content (for multi-page content)

I spent a lot of time to get this working on modern Chrome, Firefox and Safari. I use this to create a PDF from HTML. You will get header and footer fixed to each page without overlapping the page content. Try it:

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>
