Explanation of the CSS file

Index DOT Html: Main Index | Element Tree | Element Index | HTML Support History
Index DOT Css: Main Index | Property Index | CSS Support History | Browser History

I have created situation specific, CLASS-based markup on a foundation of simple formatting. This should help ensure that the site looks good on most any delivery platform. This extensive use of the CLASS structure to classify information is not highly recommended for use in HTML, but for complex informational webs like this, it is THE best solution to conquering the complexity beast in this language.

The class names used should be fairly self-explanatory - you should be able to tell what it is you are controlling by the class name. If you do not understand what some of the CSS properties or values do, or don't understand the syntax, the content of this site is the place to start.
Selector Blocks
Page Appearance rules
These control the common page background, foreground, hyperlink and rule appearances
body, dl, dt, dd,
ul, ol, li, td, th, .text
basic content properties
.gc Base display of support table cell content
hr HR properties
.field Used to set the background field of table headers
a:link unvisited hyperlinks
a:visited visited hyperlinks
Page Titles, Headers, Important Info, Generic Font Sizing
These are generic rules used in most pages to bring information to the user's attention. They control page titles, important headings, important incidental information and generic font sizing info.
.pagetitle On each page: The on-screen title of the page
.subtitle On each page: Any on-screen sub-headers of the page title
.sitetitle On each page: The name of the site
.mainheading Highest importance headings
.subheading Second level headings
.l3heading Third level headings
.alert General emphasized content
.quotation Quoted passages
.alert2 General emphasized content when 'l3heading' is skipped
.magicword Extreme emphasis content
.unselected Item in HTML/CSS/Support key jump indices indicating current category
.smalltext Generic smaller content
.largetext Generic larger content
Specific Page Titles, Headers and Subheaders, and Font
These rules are only used in some of the pages to control the display of specific content.
.indexsitetitle Main index: The name of the site
.colheaders Main index: column header content
.entityheader Used only in character entity pages to indicate column headings
.taghead Used in support grid header cells - tag/property name
.attribhead Used in support grid header cells - subcomponent name
.supporthead Used in support grid header cells - standard/browser name
Meaningful HTML/CSS syntax
All HTML tag names and attributes, CSS selectors and properties use these classes.
.tagname HTML element names
.tagattrib HTML attributes for elements
.selector CSS Selectors
.property CSS Properties
Specification/Browser Support Information
Rules controlling display of support information and color picker legends.
.fs This was the first browser/standard to support the indicated feature
.s This browser/standard supports the indicated feature, but was not the first to do so.
.sr This browser/standard supported the indicated feature, but no longer does. Contents lists start and end version support.
.ns This browser/standard does not support the indicated feature
.colorname Used in the color chooser app - indicates the color's common name
.colorvalue Used in the color chooser app - indicates the color's hex value
Unused rules
I added these classes, but have never really done anything with them. All external links and their descriptions carry the 'relevant' class. The anchors themselves can carry special behavior beyond this.
.related Used for related links
.external Used for absolute URL links to other sites
