A More Accessible Pop-Up Window - Articles Surfing
More and more commercial websites are featuring pop-ups these days. In many instances, I'm noticing more pop-ups being used for advertising, probably due to the harsh reality that is "banner blindness". In other cases, pop-ups are used to display supplemental content to the parent page. Unfortunately, many designers know little about how to make a proper pop-up window that will be accessible.
Among the many concerns of accessible design is found in "Guideline 6" of the W3C's Web Content Accessibility Guidelines: http://www.w3.org/TR/WCAG10/#gl-new-technologies - "Ensure that pages are accessible even when newer technologies are not supported or are turned off." Simply put, you should ensure that your content remains accessible to those who modify their accessibility settings to disable scripting or whose choice of adaptive technology does not recognize scripting. See also the relevant Section 508 criteria: http://www.access-board.gov/sec508/guide/1194.22.htm#(l)
Popups are among the items that most often violate this accessibility guideline
In the first case, using "#" as the hypertext reference will result, at best, in their being taken to the top of the page. The "#" sign is interpreted as what's known as a "Fragment Identifier Separator" ( see geekspeak at - http://www.w3.org/Addressing/URL/4_2_Fragments.html ). What this means to us is that the "#" is supposed to point somewhere, such as a named object on the page. It is not a default "Do Nothing" character. The hash symbol prepends the name of the target. So that <a rel="nofollow" href="#contact">Contact me</a> will take you to a place on the page that is named "contact" - <a name="contact"></a>
Using just plain "#" as the hypertext reference is bad because "A void fragment-id with or without the hash sign means that the URL refers to the whole object." In most browsers, it will be interpreted as pointing back to the beginning of the page. At best, it will do nothing when clicked.
It can be done better and work well for all
<a rel="nofollow" href="file.html" onclick="window.open('file.html', 'window_name', 'toolbar=yes, location=yes, status=yes, menubar=yes, scrollbars=yes, resizable=yes, width=xxx, height=xxx'); return false"> Open Window </a>
The use of the word "Close" might be confusing, but there are two schools of thought here.
Alternatively, you might also use the alt text attribute of a transparent spacer image: <a rel="nofollow" href="referrer.html"><img src="path/spacer.gif" width="1" height="1" border="0" alt="[Go Back]"></a> (This assumes they're also surfing with images off or on a non-graphical browser)
Ultimately, this comes down to what you hear me say so often: You cannot reliably predict the user or their settings. So don't try. Make it right and it will be usable to all.
Opening new windows is bad enough as it is. The above article only aims at showing you how to make them better. The best answer is to not use them at all. Please see the following links for details -
