Style of external links

How you would show that a link leads away from a site? Maybe
you would just say so, but I'm after something more subtle, some
stylesheet rule I can apply to external links.

Something similar to the Wikipedia's idea of a very un-saturated
off-site icon is a good plan.

If IE6 supported it, you could probably use CSS to generate a Unicode
arrow proceeding each link; I'm not sure of the specifics, though.

a class="external" href="http://www.example.com" title="External Site"
Some External Site</a

Well, for the technical means of _identifying_ external links, I had
been using class="external", but I plan to use CSS3's
A[href^="http:"].
I know, this only matches HTTP URLs and not all absolute URLs are
necessarily external, but this avoids extra markup.

.external {
background-image: url(link-external.png);
background-position: top right;
padding-right:11px;
background-repeat: no-repeat;}

Thanks, this was the sort of thing I was after. What would the image
look like?

In <URL:http://www.merlyn.demon.co.uk/uksumtim.htm> I do it with
titles: # for other site, + for other page, . for same page - e.g.
<a href="datelinx.htm" title="+">...</a>.

When the mouse-pointer reaches a link, it turns into a hand. If
it is a titled link, a cuff soon appears with a cuff-link showing
the potency of the link. The cut of the shirt is browser-
dependent.

It seems possible to scan a document onLoad with javascript and
modify the style of external links or add a title :

for (j in document.links) { X = document.links[j]
// if (X.protocol == "http:") X.style.background = "white" }
if (X.protocol == "http:") X.title = "#" }

On my Home Page, external links are bold and in-page ones italic.

Thanks for all the comments.

I like the idea of a small arrow after the link generated by
CSS. By what people here have said, using an arrow seems to
be an established practice. Generating it in CSS would at
most mean adding class="external" to the markup, and at best
avoid any extra markup. I would prefer a character instead
of an image because it would resize along with the rest of
the text.

I plan to use the following rule (once CSS3 gets a move on):

A[href^="http:"]::after{
content: " > "
}

and maybe a similar rule for mailto:.

What character would be best, I have not yet decided.

In terms of WWW authoring, I think you should allow eight years or so for
delivery (of specifications and conforming browsers). :-(

The greater than sign characters doesn't sound great. Some arrow might be
better, but any arrow might be interpreted as pointing to a particular
direction (e.g., as indicating a "forward" link).

Some months ago, there was a discussion in the public Unicode list about
adding an "external link" symbol to Unicode. Its shape was meant to resemble
the icon that Wikipedia uses for external links (an arrow that points away
from the center of a box). People were sceptic (and I surely was), but this
discussion itself suggests that existing Unicode repertoire doesn't really
contain a suitable character.

As a more realistic approach, you might use something like

<span class="extlink">(external link)</span>

together with CSS code that replaces the text by an image. (How? Some
background image technique together with setting font size to 1px? Sounds
tricky indeed.)

An icon of the globe (the Earth) might be descriptive, but it's very
difficult to make it work in the normal sizes of letters.

If you wish to refer to U+2709, then a correct character reference is
&#x2709; (and without "&" it won't be recognized at all, without the ";" it
won't be recognized by IE 7).

But why would you use an iconic image that symbolizes sending messages on
sheets of paper enclosed in envelopes and typically delivered via a postal
service, when you in fact mean a _completely_ different method of sending a
message? Would you also use an image of a horse to symbolize a car or an
image of an apple to symbolize beef?

An envelope image (or, theoretically speaking, the ENVELOPE character) would
be a suitable symbol for a _postal address_, if abuse of such symbols were
not so common.

I know that envelopes are common symbols for email on web pages. This
doesn't make such usage less stupid. It would be a different matter if such
symbolism were ubiquous, since bad symbols become good symbols when they
become universally adopted. But envelopes standing for email are normally
used on sloppily designed childish pages only, often as animated images to
make the cluelessness more obvious.
