Better Links for Print


When we print web pages we see links as underlined text either black or, if we printed in a color printer, blue or whatever color we made our links. That doesn't help us know what the actual links are.

A possible solution is to use generated content for paged media and the :after selector to insert the text of the URL after the link.

The code #

We're saving all the code in this section in a print.css file. Why we're doing this will become clear when we use the styles.

The easiest way to start is to tell the browser to add the content of the href attribute after all anchor elements (a).

a:visited::after {
  content: " (" attr(href) ") ";
  font-size: 90%;

There is a problem, this won't work with relative links, those pointing to pages within the same site that doesn't use a full URL or to anchors within the same document. We can use the ^= attribute selector to only target those links that start with http and this will only target external links, whether they are http or https; they both start with http :)

So now our code looks like this:

a[href^=http]:visited::after {
  content: " (" attr(href) ") ";
  font-size: 90%;

The final problem to deal with is overcrowding. If a paragraph has many links, the text of the links will make the paragraph hard to read, particularly if you have many long links. This will require case-by-case testing and decisions, but I've created a special case to remove the link.

If you add the no-print class to a link it will not print the URL.

That code looks like this:, {
  content: "";

So now we have both a way to print the URL of a link in parenthesis after the link and a special case to avoid printing the links when it makes sense.

Using it #

Using the styles we created is easy to link it using a link element in the head of the page and the media="print" attribute to make sure it will only get triggered when we print the page.

<link rel="stylesheet" href="main.css">
<link rel="stylesheet" media="print" href="print.css" />
