University computer use policies

The code in these pages is not to be used as template code. Policies for UNL web developers are given at the top of the source code. If you would like to use the UNL templates for your site development project, information is available at the UNL Web Developer Network site.

CSS Table-Free Templates
  Templates using CSS positioning attributes for layout were introduced in spring 2005. (For information on obtaining these templates, see above.)

Usability Fixes to Drop-Down Menus
  In order to increase accessibility for low-vision clients, we have rebuilt the drop-down menus to incorporate a 'go' button. This is required because conventional browsers, when users choose to browse by keyboard instead of by mouse, will not navigate a drop-down menu with an embedded JavaScript onChange function correctly - most browsers, when navigated by keyboard, will take the user to the first selection in the drop-down menu.

Validation as XHTML/508/WCAG 1,2,3
  The top-level pages now meet the World Wide Web Consortium's validation requirements for XHTML 1.0 Transitional code, and pass Cynthiasays testing for Sec. 508 compliance. University Communications will continue to work toward higher levels of compliance with Web Content Accessibility Guidelines standards, and will broaden standards support to all pages under development. NOTE: The Cynthiasays validator is incorrect when failing an XHTML 1.0 Transitional page for using the deprecated element 'td height.' Refer to the W3C's XHTML 1.0 Transitional validator. While it is understood that the td height attribute is being phased out, we do not anticipate its demise until we move to an all-CSS layout.

Enhanced contrast options
  The contrast setting (ISO-standard contrast button at lower left of left sidebar, in footer of external page) now controls backgrounds as well as text.

Second-level navigation
  A second level of site navigation, viewable as you mouse over the main tabs, offers one-click access to the top links from each of the index pages.

Resizeable text
  Due to recent versions of IE/Windows' inability to resize text when specified in pixel units, we have rewritten our stylesheets in percentage units, which all major browser support in their current versions. (NOTE: Resizing em-based stylesheets was found to be unworkable in IE/Windows; we recommend percentages, which are otherwise equivalent to ems, and which IE/Windows supports well.) See 'Browser support,' below, to view our policy on browsers.

Pervasive tooltips
  All links will give link information on mouseover, after a slight delay which varies by browser. Older browsers may not support this feature.

Upper-left wordmark links to home
  Standard usability convention for websites.

Weather links have moved
  Because the National Weather Service has combined forecast, radar, and current conditions into one page, we have gone from three weather buttons to one. It's at the far right of the row that begins with 'UNL Quick Links.'

  A high-contrast stylesheet may be set by clicking a button at the bottom of the left sidebar (default is normal contrast). A UNL homepage subscription selection is also possible there, allowing a local UNL user to change to the 'external,' non-content-focused homepage as their default 'UNL Home,' and external users to subscribe to 'UNL Today,' our daily digest of activity at UNL.

More info on sidebar images
  The images shown at right on the main liquid-width layouts now are linked to more information on the person or object pictured.

Browser support
  UNL University Communications tests code on all major browsers, including Internet Explorer (Windows and Mac), Netscape versions 6 and later, browsers based on the Mozilla and Gecko engines, and Safari/KHTML. We discourage the use of browsers based on the Netscape 4.x codebase, including the latest versions beginning with '4'.

  Every effort is made to deliver the same user experience to all users, regardless of what platform or browser they choose, but our codebase does not generally include browser-specific workarounds, necessary in too many cases when coding for Netscape 4.x.

Cookies currently implemented include a preference for your UNL homepage (UNL Today or static version), text contrast, and in the UNL Calendar, your last Host/Category setting. Much has been made of some privacy-related concerns, specifically the case of DoubleClick, a firm that implemented a tracking system for internet commerce sites that relied, in part, on cookies to function. The U.S. Department of Energy's Computer Incident Advisory Capability office issued an Information Bulletin, I-034: Internet Cookies, in 1998.
