Cypress is an open-source Cascading Style Sheet (CSS) parser that lets you add well-documented, standardized name/value pairs (a.k.a. CSS style properties) to your own XML markup languages. It supports inline styles so you can add style properties to individual XML tags using the style attribute or external style sheets so that you can store style rules for reuse in separate, XML-free text documents. Cypress supports three forms of selectors to match your XML tags and style rules, that is, element selectors, class selectors, and id selectors.

DOM Tooltip allows developers to add customized tooltips to Web pages. The tooltips are controlled through style class definitions and respond to events such as "mouseover", and avoids possible collisions with form elements such as select boxes and screen edges. While originally designed to create context tooltips, it is also possible to create a wide variety of dynamic layers, such as embedded windows, context menus, and hidden blocks. Additional features include sticky tips, tooltip fading, lifetime, relative positioning, class assignments, width adjustments, mouse dragging, captions, directionality, offset adjustments, adjustable activate/deactivate delay times, snapping to grid, fate adjustment (hide or destroy), and references to created tips. It supports Mozilla/Netscape6+, IE 5.5+, IE on Mac, Safari, Konqueror, and Opera 7.

To take full advantage of XEland you should learn cross-eye viewing.
