CSS Style Guide

 

This Style Guide explains the markup and design requirements for web projects, along with various standards and best practices.

projects authored in valid XHTML 1.0 Transitional and styled with valid Cascading Style Sheets will be described here. See the XHTML and CSS sections below for details. Additional sections of this Style Guide, coming soon, will provide information on writing for the web, naming and filing your documents, and other useful topics and guidelines.

Figure 7-68. Floating images and element backgrounds

There is nothing different about the second example, except for thevisible background. As you can see, the floated image sticks out ofthe bottom of its parent element. Of course, it did so in the firstexample, but it was less obvious there because we couldn't seethe background then. There is nothing forbidden about this behavior.

XHTML: Guidelines & Benefits

Library projects must be authored in structural XHTML 1.0 Transitional. Page authors should follow accessibility guidelines in compliance with U.S. Law, and so that our site’s content will be made available to the widest possible number of people, browsers, and Internet devices. In addition, all XHTML must validate.

link popularity
  • news:  = read/send to Usenet newsgroup
  • file:///  = local file access (note: 3 slashes)
  • Web servers typically have 3- or 4-part names; the last two parts comprise the registered domain name, e.g., udel.edu.  Some web servers are configured as virtual hosts serving files under multiple server names and domains.

    The path and filename in a URL are typically specified from the root

    TIP

    An easy way to remember the order in which sides have to be declared,other than thinking of it as being clockwise from the top, is to keepin mind that getting the sides in the correct order helps you avoid"trouble" -- that is, TRBL, for "Top RightBottom Left."

    It's also possible to mix up the types of length value you use.You aren't restricted to using a single length type in a givencould get something like Figure 7-66.

    7.6.1.1. Backgrounds and floats

    There are many other interesting effectsassociated with floating elements. Take the example of a shortdocument, composed of no more than a few paragraphs andH3 elements, where the first paragraph contains afloated image. Further, this floated image has a right margin of five
