Summary
.
The Project Seven Glide Panel Magic widget meets anylevel of Web standards and best practice technicalspecification and consideration.
Its
CSS
based design is highly configurable that enablesthe widget to accommodate any sound HTML design. Multiplewidgets can exist on the same content page. The widget's menustructure can be horizontal or vertical and can be locatedseparate from the content that the widget controls. The CSSdegrades gracefully in older browsers. It can be adjustedto accommodate and/or coexist with external style sheets thatcontrol primary content for all devices that support CSSand supported CSS media types.
The JavaScript is clean and succinct. For devices and useragents that do not support JavaScript or for Web visitors whodisable JavaScript, the widget content is highly structuredand usable.
It is how and in the manner which the JavaScript for thiswidget has been coded that allows the JavaScript to impactthe
DOM
ofany modern Web browser regardless of the Web page'srecognized MIME type. It further allows the script to makethe required adjustments to the DOM prior to the Web pagebeing parsed. This allows the content page to successfullyrender within the browser for either of the MIME types of
text/html
or
application/xhtml+xml
.
The
DTD
sUsed for Tests
.
These tests are based upon performance, parsing andrendering of these pages that use the various XHTML DTDs.
Performance is not an issue in pages that do not specifya DTD or use a malformed DTD. Use of such is not recommended.However, when it happens, as in the creation of much of thehobby and do–it–yourself Web content, browserswill render that content in their Quirks mode. The widgetwill function correctly in such environments.
Tests were not necessary for determination of performanceof content with a MIME type of
text/html
thatuse HTML DTDs. It would have been a redundant series of tests.
Accessibility
.
Content and developer skill dependent, this widget meetsall levels of the
WCAG
version 1.0 as published by the
W3C
As I said,it meets all levels:Priority One, Priority Two andPriority Three. This includes the United States Americanswith Disabilities Act Section 508 Accessibility Guidelines.
This content page has been machine validated against theWCAG 1.0 standard using Hiawatha's AccVerify and Watchfire'sWebXact products. No errors are reported at Priority 1,Priority 2 or Priority 3 levels.
SEO
Performance
.
The content within the widget is exposed fully to searchengines provided that the specific content is not excluded bytechnique, e.g. robot text file exclusion.
This ability is superior over standard
AJAX
techniquesthat are used to present content within a collapsible content‘fold’.
Exposing content to search engines and having the contentconveniently available to users via ‘click through’of the search engine link are distinct and separate issues.The Web developer must be cognizant of these issues. Specifictechnique and suggestions are provided within the
Application Test
content page ofthis Web site and address these issues.
