Images

1. All content images used in the home page and all pages include descriptive ALT attributes. Purely decorative graphics include null ALT attributes.

Visual design

This site and all its pages use cascading style sheets for visual layout.

1. Internet Explorer has a limited text resizing feature ("View" menu, "Text Size"), but it only works with relative font sizes. A special stylesheet that uses relative font sizes is automatically served to visitors using Internet Explorer.
2. If your browser or browsing device does not support stylesheets at all, the content of each page is still readable.
