Screen readers need to be able to read the group name or "question" in addition to each field's individual label. For example, a set of radio buttons may provide different "answers" to a single "question." Why: In some cases, several form fields may need to be grouped together.

Because screen readers typically recognize either the or the title (not both), the title must provide the full label, and a should not be associated with the field.įor buttons ( ), use the value attribute to provide a label for image buttons ( ), use the alt attribute for the label. Set the label element's for attribute to match the corresponding field's id, e.g.:Īdd a title attribute to any form field that cannot be associated with a. Use a element whenever possible to identify each form field's label. Proper use of the HTML element and/or title attribute makes this association clear. Screen readers cannot always determine which label belongs to which field based on positioning alone. In HTML, labels are identified using the tag. Each field is typically identified by a text label positioned above, before, or below the field.
HTML forms include "fields" such as text boxes ( ), check boxes ( ), radio buttons ( ), and drop-down lists ( ). invisible ġ0.1 - Provide labels or titles for all form fields. Note: Headings (and other elements) may be hidden visually but revealed to assistive technologies using a style such as: Use Cascading Style Sheets (CSS) to control the size and appearance of headings. If the page is long enough to be divided into sections, group each section in a and begin each with a heading of the appropriate level: Start the main content area of each page with an heading that indicates the topic of the page as identified in the page title. Screen readers identify headings so that users can easily skim through content and quickly skip to sections of interest. Web browsers normally display headings in large, bold font. HTML includes six levels of headings (, ,, ,, and ), representing the different levels in an "outline" of the page. Headings are used to introduce sections and sub-sections within a page. Ref:ġ.4 - Use headings to introduce sections and sub-sections, and use them in the correct order. Use the W3C HTML Validation Service () to check your code.

ILLINOIS FONT CODE
How:įor web pages, indicate the programming language you are using by starting your code with a standard document type declaration, such as: Screen readers and other assistive technologies most reliably interpret and interact with web pages that are built using valid, standard code. Valid code is the foundation for accessibility. Programming code is considered "valid" when it follows the rules and conventions specified in the published standards. The World Wide Web Consortium (W3C) sets and publishes standards for web programming languages including HyperText Markup Language (HTML/XHTML), and Cascading Style Sheets (CSS).
1.1 - Use valid, standard web programming code.
