I have to agree about using body class instead of id. Here's what I'm using on one page body class="sub3 sub3sub1 sub3sub1sub4 asub3sub1sub4"
This set of classes match with a set of id's in a nested list that is used for navigation. This has allowed me to open, close, change background colors, add icons to show that a parent list is open for children, etc. You can use multiple classes but multiple id's in a tag can create problems. For more info on this, I sent the entire css sheet to this mailing list a couple months ago, it's probably in the archive under "when navigation lists go bad" or some silly name like that.

This is a good habit, IMO, although technically the body tag is unique on the page and so many pages on the site can have a body tag with the same id -- IDs need only be unique per document. There are two reasons it's still useful (AFAICS) to make body IDs unique on the site, and classes non-unique: 1. You may be coding in XHTML, which may give you the ability in the future to do something entirely wacky like dump every page in your site into a single XML file. Then you'd want your XPath query to be able to home right in on a single body element. 2. Class attributes are a space-delimited list, allowing you to stack up the categories the body belongs to. I use this technique to define a range of layout types, which may be content- or section-specific, like so: <body id="pageBioPubIntphoto" class="sectionBio sectionPub layoutText"> The "page___" and "section___" identifiers are derived directly from the path, and the "layoutText" class in this case sets black text on white background (the "layoutPic" is mostly pictures, with a black background and subordinated grayish text). With this technique, you can do more than change the background per page, section, or layout type. You can also, for example, set specific dynamic submenus to appear or hide, or layouts with the same IDs can be radically shifted. -- Ben Curtis : webwright bivia : a personal web studio http://www.bivia.com v: (818) 507-6613 ****************************************************** The discussion list for http://webstandardsgroup.org/ See http://webstandardsgroup.org/mail/guidelines.cfm for some hints on posting to the list & getting help ****************************************************** ****************************************************** The discussion list for http://webstandardsgroup.org/ See http://webstandardsgroup.org/mail/guidelines.cfm for some hints on posting to the list & getting help ******************************************************
