We have made several considerations during the design of this website. Above all else, we believe content should be accessible to all users, regardless of viewing device, screen size, language, or other unique and unforseen challenges. With this in mind, our site heavily relies on the use of Cascading Style Sheets to visually style the layout of our site. This strategy allows devices to gracefully degrade the visual layout of the site while maintaining content accessibility.
In addition to the detailed accessibility information provided below, we also considered the following technical details (provided July 2007 - source):
- 57% of browser-based website traffic is using Internet Explorer 6 or 7.
- 34.5% of browser-based website traffic is using Mozilla Firefox.
- 80% of browser-based website traffic is using a resolution at or above 1024 x 768 pixels.
Standards complianceIt is our ongoing effort to ensure all pages found within www.cityofnapa.org comply with the following accessibility standards and guidelines:
- Bobby AAA guidelines.
- WCAG AAA priority 2 (current) of the W3C Web Content Accessibility Guidelines.
- U.S. Federal Government Section 508 Guidelines.
- All pages on this site use structured semantic markup, as provided by the W3C XHTML 1.0 Recommendations. Unfortunately, due to circumstances beyond our reasonable control, not all pages validate to the XHTML standards.
- All pages have rel=previous, next, up, and home links to aid navigation in text-only browsers. Netscape 6 and Mozilla users can also take advantage of this feature by selecting the View menu, Show/Hide, Site Navigation Bar, Show Only As Needed (or Show Always).
- The home page and all archive pages include a search box (access key 4).
- Many links have title attributes which describe the link in greater detail, unless the text of the link already fully describes the target (such as the headline of an article).
- Links are written to make sense out of context.
- Where possible, all content images used in this site include descriptive ALT attributes. Purely decorative graphics include null ALT attributes.
- Where possible, complex images include LONGDESC attributes or inline descriptions to explain the significance of each image to non-visual readers.
- This site uses cascading style sheets for visual layout.
- This site uses only relative font sizes, compatible with the user-specified "text size" option in visual browsers.
- If your browser or browsing device does not support stylesheets at all, the content of each page is still readable.
