Ludzie pragną czasami się rozstawać, żeby móc tęsknić, czekać i cieszyć się z powrotem.
..
? clearly identify the target of each link; choose meaningful words or phrases for links.
? adjacent links should be separated (not only with carriage return, use text or graphic)
? keep links underlined so screen readers can recognize them, and do not underline text that is not a link
? add keyboard shortcuts to important links (LABEL, A , CAPTION, LEGEND)
...
? consider including internal links within longer pages so viewers can jump from section to section with a single click
? Regularly check all the links from your site to make sure they are current.
Auditory and visual content
? make all graphical links and buttons large and easy to click on
? provide text equivalents for non-text content (images, symbols, image map regions, animations, applets, ASCII art, frames, scripts, images used as list bullets, spacers, graphical buttons, sounds, stand-alone audio files, video, ...)
? use alt="" for visuals that do not convey important information
? don't rely on color alone
? using background patterns or floating text over images is distracting and makes the page much harder, if not impossible, to read for many viewers
? ensure that foreground and background color combinations provide sufficient contrast (color combinations such as brown on tan or green on gray are not good choices; avoid combinations of blue and yellow or red and green for viewers with certain types of color blindness)
? ensure that your chosen color scheme may be over-ridden by the browser setting if necessary
? ensure that moving, blinking, scrolling and auto-updating objects or pages may be paused or stopped (for some people with cognitive or visual disabilities)
? provide client-side image maps to provide accessible text for image map hot spots; if you use server-side maps, provide equivalent text links
? provide captions or transcripts of audio content
? provide text or audio description of video content
? use relative units rather than absolute units
Frames
? provide a title for each frame so that users can track frames by title
? don't suppress frame scrolling; you can't foresee which resolution, text size, fonts and other options will the user have
General
? Date stamping your pages when content is updated or edited lets viewers know how current your site or information is and increases their confidence in your content.
? Setting up a search engine on your site will help users to "jump on" what they are looking for.
? Organize archives in a logical manner, by year or by topic, for example, and allow people to search by key words.
The ideal web site
is not the one, which is attractive for a group of people,
but the site, which everyone can visit
and obtain the same amount of information.
