CSS image replacement is a Web design technique that uses Cascading Style Sheets to replace text on a Web page with an image containing that text. It is intended to keep the page accessible to users of screen readers, text-only web browsers, or other browsers where support for images or style sheets is either disabled or nonexistent, while allowing the image to differ between styles.
The template will place an image with a superimposed text: align - left, right; alignment of image in article; x, y - position of text inside image; in pixels, from the upper left corner; base_img - background image file; use just the name, without the "Image:" tag; base_width - width of background image in pixels
Instead, the style is defined in an external style sheet file using a style sheet language such as CSS or XSLT. This design approach is identified as a "separation" because it largely supersedes the antecedent methodology in which a page's markup defined both style and structure.
The user can customize fonts, colors, positions of links in the margins, and many other things! This is done through custom Cascading Style Sheets stored in subpages of the user's "User" page.

Inheritance is the mechanism by which properties are applied not only to a specified element but also to its descendants. Inheritance relies on the document tree, which is the hierarchy of XHTML elements in a page based on nesting. Descendant elements may ...
Most style sheet languages have a visual formatting model that describes, in some detail, how text and other content is laid out in the final presentation. For example, the CSS formatting model specifies that block-level elements (of which "h1" is an example) extend to fill the width of the parent element. Some style sheet languages also have ...
