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.
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.

Sometimes, of course, a pregenerated bullet just won't do. Instead, you feel the need to use an image for each bullet. In the past, the only way to achieve this sort of effect was to fake it. Now all you need is a list-style-image declaration.

CSS: Style Sheets & Tips
Library projects must use valid Cascading Style Sheets (CSS) to control typography, color, and other layout elements. Style Sheets must be linked in a way that accommodates the capabilities of new and old browsers.
A number of valid Style Sheets have been provided for your use. If you wish to create your own Style Sheets, please discuss your requirements with the Branch Library’s Web Coordinator.
link popularitystraightforward, and the complexities so minimal, that this will probably all come as a great relief. First we'll talk about font-style, and then move on to font-variant before wrapping up the font properties.

font-style is very simple: it's used to select between normal text,headline, e.g., <H2 ALIGN="center"> or page division <DIV ALIGN="right">. Each of these should terminate with a corresponding termination tag </P>, </H2> or </DIV> as appropriate.
The block-level <CENTER> tag is still a commonly-used alternative (includes its own line breaks). Use <BLOCKQUOTE> for both-margin indents, <UL> with no list items for left-indents (see below).
margin can accept any length measure, whether inpixels, inches, millimeters, or ems. However, the default value formargin is effectively 0 (zero),which means that if you don't declare a value, then by default,there won't be a margin.
Negative margins have an impact on vertical formatting, affecting how margins are collapsed. If there are negative vertical margins, then the browser should take the absolute maximum of the negative margins and subtract that from the maximum of any positive margins.
In the case where there are only two margins to be collapsed, one positive and the other negative, the situation is handled in a fairly simple manner. The absolute value of the negative margin is
