Success Criterion 4.step one.2 Label, Role, Well worth
For everybody screen portion (together with however restricted to: form issue, website links and you can components made by texts), the name and you can character would be programmatically calculated; claims, characteristics, and you can viewpoints that may be lay of the representative should be programmatically set; and you can alerts out-of change to the points is available to representative representatives, along with assistive tech.
Achievement Standards 4.step one.3 Position Messages
From inside the articles followed having fun with matically computed through character otherwise attributes including that they can become presented to an individual of the assistive innovation in the place of choosing focus.
5. Conformance
This area listings conditions getting conformance so you can WCAG 2.step 1. it provides here is how and also make conformance says, which happen to be elective. Ultimately, they refers to what it means to become access to supported, because only usage of-served way of playing with innovation would be relied abreast of to own conformance. Understanding Conformance has after that factor of your usage of-served layout.
5.step one Interpreting Normative Requirements
An element of the content out-of WCAG 2.step one is actually normative and you can talks of standards you to definitely perception conformance claims. Basic material, appendices, parts ples, and you will cards try educational (non-normative). Non-normative topic brings consultative recommendations to aid translate the guidelines but does not do conditions you to impression an excellent conformance allege.
The key conditions Could possibly get, Need to, Cannot, Not advised, Necessary, Would be to, and cannot will be translated since the revealed from inside the [ RFC2119 ].
5.2 Conformance Standards
So a web site to help you follow WCAG 2.1, most of the after the conformance requirements must be came across:
5.dos.step one Conformance Level
- For Level A conformance (the minimum amount of conformance), the web pagesatisfies every Level An emergency Requirements, otherwise a compliant solution variation exists.
- To have Peak AA conformance, the internet site satisfies the Top A and you may Level AA Triumph Conditions, otherwise a level AA conforming alternate type emerges.
- To own Peak AAA conformance, the internet site joins most of the Top An effective, Height AA and Top AAA Triumph Criteria, otherwise an amount AAA compliant approach adaptation emerges.
Even when conformance can only be performed in the said membership, authors are encouraged to declaration (in their claim) any progress with the conference achievements standards from every account outside the hit quantity of conformance.
This isn’t better if Level AAA conformance be required since a general plan for entire internet sites because it’s difficult to meet every Top AAA Victory Criteria for most content.
5.dos.2 Complete profiles
Conformance (and you can conformance level) is for complete Web page(s) just, and should not be done if the section of an internet site . is excluded.
For the intended purpose of determining conformance, selection in order to part of a page’s posts are considered element of the newest web page when the alternatives is available directly from brand new webpage, e.grams., a long breakdown or an option speech regarding a video clip.
Writers from Internet sites that simply cannot conform due to blogs outside of author’s handle can get envision an announcement of Limited Conformance.
A webpage has per variation of one’s webpage which is immediately displayed from the webpage for several screen brands (e.g. differences in a receptive Web page). All these distinctions must hold (otherwise will need to have a conforming alternative version) to ensure the complete webpage to stick.
5.dos.3 Over techniques
When a web site is among the most a series of Web users to present a process (i.age., a sequence regarding tips that have to be finished in acquisition to do a job), every Internet sites in the act conform at given level or better. (Conformance isn’t feasible at a certain top if any page along the way does not stick at this peak or top.)
