What is accessibility? - Learn web development
for a start, the w3c has published a large and very detailed document that includes very precise, technology-agnostic
criteria for accessibility conformance.
...the
criteria are split up into four main categories, which specify how implementations can be made perceivable, operable, understandable, and robust.
...there is no need to learn all of the wcag — be aware of the major areas of concern, and use a variety of techniques and tools to highlight any areas that don't conform to the wcag
criteria (see below for more).
Strategies for carrying out testing - Learn web development
consider the following example (see the source code, and also the example running live): test
criteria for this feature could be written like so: a and b grade: button should be activatable by the user's primary control mechanism, whatever it is — this should include mouse, keyboard, and touch.
... these test
criteria are useful, because: they give you a set of steps to follow when you are performing tests.
...we mentioned this in the what are you going to test section above — it is easy to turn the test
criteria detailed there into steps to follow.
MailNews Filters
for each new header, we evaluate the filter
criteria and apply the actions synchronously, including moving a message to an other local folder, and advance to the next header.
...this is implemented by doing a search using the filter
criteria and applying the actions en masse on the resulting hits.
... the search is executed locally, not on the server, so that
criteria like "in address book" still work.
Debugger - Firefox Developer Tools

Robust - Accessibility
this article provides practical advice on how to write your web content so that it conforms to the success
criteria outlined in the robust principle of the web content accessibility guidelines (wcag) 2.0 and 2.1.

At-rules - CSS: Cascading Style Sheets
nested at-rules — a subset of nested statements, which can be used as a statement of a style sheet as well as inside of conditional group rules: @media — a conditional group rule that will apply its content if the device meets the
criteria of the condition defined using a media query.
... @supports — a conditional group rule that will apply its content if the browser meets the
criteria of the given condition.
... @document — a conditional group rule that will apply its content if the document in which the style sheet is applied meets the
criteria of the given condition.
Content negotiation - HTTP
the header is needed in order to inform the cache of the decision
criteria so that it can reproduce it, allowing the cache to be functional while preventing serving erroneous content to the user.
...a cache, in order to work with server-driven content negotiation, needs to know which
criteria was used by the server to select the transmitted content.
...besides falling back to the server-driven negotiation, this method is almost always used in conjunction with scripting, especially with javascript redirection: after having checked for the negotiation
criteria, the script performs the redirection.
