Easy-to-use cross-browser tooltips.
Just include the script at the beginning of the section, and invoke
Tip('Tooltip text') from within the desired HTML onmouseover eventhandlers.
No container DIV, no onmouseouts required.
By default, width of tooltips is automatically adapted to content.
Is even capable of dynamically converting arbitrary HTML elements to tooltips
by calling TagToTip('ID_of_HTML_element_to_be_converted') instead of Tip(),
which means you can put important, search-engine-relevant stuff into tooltips.
Appearance of tooltips can be individually configured
via commands passed to Tip() or TagToTip().

var TagsToTip = true // false or true - if true, the script is capable of converting HTML elements to tooltips
// For each of the following config variables there exists a command, which is
// just the variablename in uppercase, to be passed to Tip() or TagToTip() to
// configure tooltips individually. Individual commands override global
// configuration. Order of commands is arbitrary.
// Example: onmouseover="Tip('Tooltip text', LEFT, true, BGCOLOR, '#FF9900', FADEIN, 400)"

config. CloseBtn = false // false or true - closebutton in titlebar
config. CloseBtnColors = ['#990000', '#FFFFFF', '#DD3333', '#FFFFFF'] // [Background, text, hovered background, hovered text] - use empty strings '' to inherit title colors
config. CloseBtnText = ' X ' // Close button text (may also be an image tag)
config. CopyContent = true // When converting a HTML element to a tooltip, copy only the element's content, rather than converting the element by its own
config. Delay = 20 // Time span in ms until tooltip shows up
config. Duration = 0 // Time span in ms after which the tooltip disappears; 0 for infinite duration
config. FadeIn = 0 // Fade-in duration in ms, e.g. 400; 0 for no animation
config. FadeOut = 0
config. FadeInterval = 0 // Duration of each fade step in ms (recommended: 30) - shorter is smoother but causes more CPU-load
config. Fix = null // Fixated position - x- an y-oordinates in brackets, e.g. [210, 480], or null for no fixation
config. FollowMouse = true // false or true - tooltip follows the mouse
config. FontColor = '#003D71'
config. FontFace = 'Verdana,Geneva,sans-serif'
config. FontSize = '8pt' // E.g. '9pt' or '12px' - unit is mandatory

config. OffsetY = 10 // Vertical offset
config. Opacity = 100 // Integer between 0 and 100 - opacity of tooltip in percent

config. TitleAlign = 'left' // 'left' or 'right' - text alignment inside the title bar
config. TitleBgColor = '' // If empty string '', BorderColor will be used
config. TitleFontColor = '#ffffff' // Color of title text - if '', BgColor (of tooltip body) will be used
