This site aims to help our audience with the tools and understanding which will enable them to make the most of the world-wide web whatever their ability or disability.
- All images, form image buttons, and image map hot spots have appropriate, equivalent alternative text.
- Images that do not convey content, are decorative, or with content that is already conveyed in text are given null alt text (alt="") or implemented as CSS backgrounds. All linked images have descriptive alternative text.
- Equivalent alternatives to complex images are provided in context or on a separate (linked and/or referenced via longdesc) page.
- Form buttons have a descriptive value.
- Form inputs have associated text labels or, if labels cannot be used, a descriptive title attribute.
- Embedded multimedia is identified via accessible text.
- Frames are appropriately titled.
1.3.1 Info and Relationships
- Semantic markup is used to designate headings (<h1>), lists (<ul>, <ol>, and <dl>), emphasized or special text (<strong>, <code>, <abbr>, <blockquote>, for example), etc. Semantic markup is used appropriately.
- Tables are used for tabular data. Where necessary, data cells are associated with their headers. Data table captions and summaries are used where appropriate.
- Text labels are associated with form input elements. Related form elements are grouped with fieldset/legend.
1.3.2 Meaningful Sequence
- The reading and navigation order (determined by code order) is logical and intuitive.
1.3.3 Sensory Characteristics
- Instructions do not rely upon shape, size, or visual location (e.g., "Click the square icon to continue" or "Instructions are in the right-hand column").
- Instructions do not rely upon sound (e.g., "A beeping sound indicates you may continue.").
Use of Color
- Color is not used as the sole method of conveying content or distinguishing visual elements.
- Color alone is not used to distinguish links from surrounding text unless the luminance contrast between the link and the surrounding text is at least 3:1 and an additional differentiation (e.g., it becomes underlined) is provided when the link is hovered over or receives focus.
- Text and images of text have a contrast ratio of at least 4.5:1.
- Large text (over 18 point or 14 point bold) has a contrast ratio of at least 3:1
The page is readable and functional when the text size is doubled.
Images of Text
If the same visual presentation can be made using text alone, an image is not used to present that text.
- Text and images of text have a contrast ratio of at least 7:1.
- Large text (over 18 point or 14 point bold) has a contrast ratio of at least 4.5:1
- Blocks of text over one sentence in length: Are no more than 80 characters wide.
- Are NOT fully justified (aligned to both the left and the right margins).
- Have adequate line spacing (at least 1/2 the height of the text) and paragraph spacing (1.5 times line spacing).
- Have a specified foreground and background color. These can be applied to specific elements or to the page as a whole using CSS (and thus inherited by all other elements).
- Do NOT require horizontal scrolling when the text size is doubled.
Images of Text
Text is used within an image only for decoration (image does not convey content) OR when the information cannot be presented with text alone.
- All page functionality is available using the keyboard, unless the functionality cannot be accomplished in any known way using a keyboard (e.g., free hand drawing).
- Page-specified shortcut keys and accesskeys (accesskey should typically be avoided) do not conflict with existing browser and screen reader shortcuts.
- All page functionality is available using the keyboard.
Reauthenticating: Bypass Blocks
- A link is provided to skip navigation and other page elements that are repeated across web pages.
- If a page has a proper heading structure, this may be considered a sufficient technique instead of a "Skip to main content" link. Note that navigating by headings is not yet supported in all browsers.
- If a page uses frames and the frames are appropriately titled, this is a sufficient technique for bypassing individual frames.
The web page has a descriptive and informative page title.
The navigation order of links, form elements, etc. is logical and intuitive.
The purpose of each link (or form image button or image map hotspot) can be determined from the link text alone, or from the link text and it's context (e.g., surrounding paragraph, list item, table cell, or table headers).
Links (or form image buttons) with the same text that go to different locations are readily distinguishable.
Headings and Labels
Page headings and labels for form and interactive controls are informative. Avoid duplicating heading (e.g., "More Details") or label text (e.g., "First Name") unless the structure provides adequate differentiation between them.
It is visually apparent which page element has the current keyboard focus (i.e., as you tab through the page, you can see where you are).
If a web page is part of a sequence of pages or within a complex site structure, an indication of the current page location is provided, for example, through breadcrumbs or specifying the current step in a sequence (e.g., "Step 2 of 5 - Shipping Address").
- The purpose of each link (or form image button or image map hotspot) can be determined from the link text alone.
- There are no links (or form image buttons) with the same text that go to different locations.
Beyond providing an overall document structure, individual sections of content are designated using headings, where appropriate.
- Content and interface are understandable Guideline 3.1
- Readable: Make text content readable and understandableSuccess Criteria WebAIM's Recommendations
(Level AA) Navigation links that are repeated on web pages do not change order when navigating through the site.
(Level AA) Elements that have the same functionality across multiple web pages are consistently identified. For example, a search box at the top of the site should always be labeled the same way.
Labels or Instructions
(Level A) Sufficient labels, cues, and instructions for required interactive elements are provided via instructions, examples, properly positioned form labels, and/or fieldsets/legends.
Provide instructions and cues in context to help in form completion and submission.
