Web Standards Checklist to Make a Proper Website Part IV
Accessibility for users ::
- Are "alt" attributes used for all descriptive images?
Ans :: Provide a text equivalent for every non-text element - Does the site use relative units rather than absolute units for text size?
Ans :: Use relative rather than absolute units in markup language attribute values and style sheet property values'. - Do any aspects of the layout break if font size is increased?
Ans :: Try this simple test. Look at your website in a browser that supports easy incrementation of font size. Now increase your browser's font size. And again. And again... Look at your site. Does the page layout still hold together? It is dangerous for developers to assume that everyone browses using default font sizes. - Does the site use visible skip menus?
Ans :: A method shall be provided that permits users to skip repetitive navigation links.Group related links, identify the group (for user agents), and, until user agents do so, provide a way to bypass the group.
...blind visitors are not the only ones inconvenienced by too many links in a navigation area. Recall that a mobility-impaired person with poor adaptive technology might be stuck tabbing through that morass.
- Does the site use accessible forms?
Ans :: Forms aren't the easiest of things to use for people with disabilities. Navigating around a page with written content is one thing, hopping between form fields and inputting information is another. - Does the site use accessible tables?
Ans :: For data tables, identify row and column headers... For data tables that have two or more logical levels of row or column headers, use markup to associate data cells and header cells. - Is there sufficient color brightness/contrasts?
Ans :: Ensure that foreground and background color combinations provide sufficient contrast when viewed by someone having color deficits. - Is color alone used for critical information?
Ans :: Ensure that all information conveyed with color is also available without color, for example from context or markup.There are basically three types of color deficiency; Deuteranope (a form of red/green color deficit), Protanope (another form of red/green color deficit) and Tritanope (a blue/yellow deficit- very rare).
- Is there delayed responsiveness for dropdown menus?
Ans :: Users with reduced motor skills may find dropdown menus hard to use if responsiveness is set too fast. - Are all links descriptive?
Ans :: Link text should be meaningful enough to make sense when read out of context - either on its own or as part of a sequence of links. Link text should also be terse.
