HTML to print

HTML to print allow you to create print layouts for your web pages.

You can create a PDF from you page, by print the page within the browser, and choose «Print to file».

CCS for print

Specific CSS rules allow you to specify how a webpage that was designed for screens, will be displayed in a page layout.


@page

@page rule defines context for printing.

It describes the characteristic of sheet where web page is going to be printed on.

https://developer.mozilla.org/en/docs/Web/CSS/@page

@page property: size

Possible values size: A5, A4, A3, landscape, portrait

Note: Only Chromium's print preview can take the format specified by the CSS

@page {
size: A4 landscape;
}

left and right @page

Pseudo-class selectors for the left and right pages

@page :left {
  margin-left: 3cm;
}

@page :right {
  margin-left: 4cm;
}

specific pages

Couldn't get specific pages work

@page :first {

}

The :blank pseudo-class selector targets any page that is “intentionally left blank.” To add this text, we can use generated content that targets the top-center margin box.

@page :blank {
  @top-center { content: "This page is intentionally left blank." }
}

@media queries

@media CSS rules or media queries defines specific contexts, under which specific CSS rules can be used.

https://developer.mozilla.org/en-US/docs/Web/CSS/Media_Queries/Using_media_queries For print:

 @media print {
    body {font-size: 12pt;}  
    img { width: 300px;}
 }

For screen:

 @media screen {  
    body {font-size: 14pt;}  
    img { width: 800px;}
 }

For screens with width smaller than 600px:

@media (max-width: 600px) { {  
    body {font-size: 10pt;}  
    img { width: 200px;}
 }

@media print

You can decide to style very differently you page when it is printed.

You can use it to explore how the way information is displayed influences its message.

page vs. screen

  • print exists in the space of the page, with fixed page dimensions and breaks
  • a webpage exists in a continuous screen space, often with varying dimensions

page breaks of the document

To control where the pages break, in HTML to print, is tricky, and in part you don't control it.

What you can control is what elements must, can or cannot break, before, after, or inside themselves.

In CSS in translates to the rules:

page-break-before; page-break-after; page-break-inside 

And values

always; auto; avoid;

Example:

@print {
 h1, h2, h3, h4, h5 {
  page-break-after: always;
}

p, table, figure {
  page-break-inside: avoid;
}
}
