I implemented a tooltip with picture that resembles the real ones, and here is the code:
$("[ctitle]").hover(
function(e) {
$("<div id='txt'>").css({
"display": "none",
"width": "auto",
"height": "auto",
"color": "#767676",
"border": "solid 1px #767676",
"font-size": "12px",
"font-family": "Arial",
"position": "absolute",
"padding": "2px 3px 2px 3px",
"background-color": "white",
"box-shadow": "3px 3px 1px gray",
"left": 0,
"top": 0
}).appendTo("body").html($(this).attr('ctitle')).stop().fadeToggle().css({
"top": e.pageY,
"left": e.pageX
});
},
function() {
$("[id='txt']").stop().fadeToggle(function(){
$(this).remove();
})
}
);
Basically add the code to your page (include JQuery) and use ctitle instead of title. In the ctitle attribute you can add other HTML codes to format.
