CSS: Steal These Style Sheets!

The two CSS files linked from this page can be used as-is, or modified to the design requirements of your site.

Simple Style Sheet
  1. Sets body margins and padding to zero (no offset);
  2. establishes text, background, and various stage link colors;
  3. sets text font family to Georgia, Palatino, or equivalent but does not set size (sophisticated style sheet does that);
  4. establishes link rollover effect;
  5. sets up paragraph leading (line-height) of 150%;
  6. turns off gaps and borders around images
  7. establishes pseudo-classes for control of vertical whitespace
  8. establishes font-family and relative size relationships of headlines and subheads—also their margins;
  9. provides additional pseudo-classes for special design requirements
  10. assuming CSS file resides in /styles/ directory within root directory, file should be linked to from header thusly:
    <link rel="Stylesheet" href="/styles/simple.css" type="text/css" media="screen" />
Sophisticated Style Sheet
  1. Sets paragraph font size to small (CSS font-size keyword), enabling text to be resized in most browsers;
  2. works around CSS bugs in IE4/5/5.5/Win and Opera 4/5;
  3. hides size rule from Netscape 4
  4. assuming CSS file resides in /styles/ directory within root directory, file should be linked to from header thusly:
    <style type="text/css" media="all">@import "/styles/sophisto.css";</style>

Linking

The following shows the proper way to link to both style sheets:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ">

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
        <head>

<title>NYPL: Your Site Title</title>

<link rel="stylesheet" href="/styles/simple.css" type="text/css" media="screen" />

<style type="text/css" media="all">@import "/styles/sophisto.css";</style>

<meta http-equiv="content-type" content="text/html; charset=iso-8859-1" />
<meta http-equiv="expires" content="-1" />
<meta http-equiv= "pragma" content="no-cache" />
<meta name="author" content="Your Name or New York Public Library" />
<meta name="robots" content="all" />
<meta name="MSSmartTagsPreventParsing" content="true" />
<meta name="description" content="Your subject matter described." />
<meta name="keywords" content="your, key, words, here" />

        </head>

text, however, the difference between font-sizeand line-height is 12px . Thisis divided in half to determine the half-leading(6px), and the half-leading is subtracted fromboth the top and bottom of the content-height to arrive at an inlinebox which is, in this case, 12px high. This12-pixel inline box is centered vertically within the content-heightof the element.

So far it sounds like we've done the same thing to each bit of


By using XML and Java, you can quickly create and use information that is properly structured and valid. By using (or creating) DTDs and storing your information in XML documents, you have a cross-platform and language independent data validation mechanism (for free) in all your projects!

You might use XML to define file formats to store information that is generated and used by your applications. This is another use of the structured nature of XML. The only limitation is that binary information can't be embedded in the body of XML documents. For example, if you wrote a word processor in Java, you might choose to save your word processor documents to an XML (actually your ApplicationML) file. If you use a DTD then your word processor would also get input file format validation as a feature for free. There are many other advantages to using XML and a file storage format for your applications which will be illustrated later in the chapter.

Here are some benefits of the structured nature of XML:
