Miami-Dade County Web Accessibility Guidelines

§ 1194.22 Web-based intranet and internet information and applications.

Miami-Dade County web pages
|
| (a) A text equivalent for every non-text element shall be provided (e.g., via "alt", "longdesc", or in element content). |
All images shall provide a text equivalent using the “alt” tag. |
| (b) Equivalent alternatives for any multimedia presentation shall be synchronized with the presentation. |
Movies or animations should be delivered to users only on demand and not launch when the page loads. If multimedia presentations are made available, captions or audio descriptions of the visuals must be included. |
| (c) Web pages shall be designed so that all information conveyed with color is also available without color, for example from context or markup. |
Text should be presented in black as the required color. Do not use alternate colors which may present different visual cues to different users. Color should not be used to accent text. Underlined text should only be used to denote hypertext links. The underlined text will appear as blue in most browsers. |
| (d) Documents shall be organized so they are readable without requiring an associated style sheet. |
At the present time style sheets should not be used. Organize your content logically, with the most important items first. |
| (e) Redundant text links shall be provided for each active region of a server-side image map. |
Do not use image maps as navigational elements. Images with “active regions” are considered to be maps and require text equivalents. |
| (f) Client-side image maps shall be provided instead of server-side image maps except where the regions cannot be defined with an available geometric shape. |
Server-side image maps tend to be device-specific, so alternative input devices may not allow accessibility. Content developers must ensure that visual regions can be activated without the use of a pointing device. |
| (g) Row and column headers shall be identified for data tables. |
When tables of information are included on your page, they should be introduced with a summary of the information. Each column or row should be identified with a label. |
| (h) Markup shall be used to associate data cells and header cells for data tables that have two or more logical levels of row or column headers. |
For more complicated tables. HTML should be written so that the relationships between the header and data cells are clear. |
| (i) Frames shall be titled with text that facilitates frame identification and navigation. |
Frames are not to be used. |
| (j) Pages shall be designed to avoid causing the screen to flicker with a frequency greater than 2 Hz and lower than 55 Hz. |
Flickering or flashing images or screens may cause seizures in some users who have epilepsy. Quick changes of dark to light (strobe effects) or animated effects moving in 59 cycles per second or less may have similar effects. Since screen refresh rates are controlled at the user end, the content developer can not control the viewers experience in this regard. Therefore, the animated objects and flash are not to be used. |
| (k) A text-only page, with equivalent information or functionality, shall be provided to make a web site comply with the provisions of this part, when compliance cannot be accomplished in any other way. The content of the text-only page shall be updated whenever the primary page changes. |
Our primary pages are text-based. This eliminates most of the need for alternate, text-only type pages. |
| (l) When pages utilize scripting languages to display content, or to create interface elements, the information provided by the script shall be identified with functional text that can be read by assistive technology. |
Scripts must contain text notations that are readable by assistive technology. |
| (m) When a web page requires that an applet, plug-in or other application be present on the client system to interpret page content, the page must provide a link to a plug-in or applet that complies with §1194.21(a) through (l). |
Each page that contains items which require plug-ins to access the content must contain a link to the plug-in or applet. For instance, on pages with listings of available pdf documents, the standard language and link to Adobe must be provided on that page. |
| (n) When electronic forms are designed to be completed on-line, the form shall allow people using assistive technology to access the information, field elements, and functionality required for completion and submission of the form, including all directions and cues. |
Forms should be designed so they can be navigated and completed without the use of pointing devices such as mice. Visual elements such as Submit buttons must have alternative text available. |
| (o) A method shall be provided that permits users to skip repetitive navigation links. |
Several alternative methods are provided for navigation. Each web has a set of links in the left column, there are footer links at the bottom of each page and affinity buttons or logo links at the top. |
| (p) When a timed response is required, the user shall be alerted and given sufficient time to indicate more time is required. |
Do not require timed |
