Heb je een feestje te geven? Of bestaat je website zoveel jaar en zoveel maanden? :-)
Dan is dit een leuk scriptje om dat te laten zien !

Plaats onderstaand script tussen de bodytags van je pagina:

<script language="JavaScript1.2"> <!-- Begin var no = 65; // hoeveel ballonetjes moeten er opstijgen? var speed = 2; // hoe lager je het nummer zet hoe harder de ballonen opstijgen var ballon = new Array(); ballon[0] = "redbaloon.gif" ballon[1] = "greenbaloon.gif" ballon[2] = "whitebaloon.gif" var ns4up = (document.layers) ? 1 : 0; var ie4up = (document.all) ? 1 : 0; var ns6up = (document.getElementById&&!document.all) ? 1 : 0; var dx, xp, yp; var am, stx, sty; var doc_width = 800, doc_height = 1800; if (ns4up||ns6up) { doc_width = self.innerWidth; doc_height = self.innerHeight; } else if (ie4up) { doc_width = document.body.clientWidth; doc_height = document.body.clientHeight; } dx = new Array(); xp = new Array(); yp = new Array(); am = new Array(); stx = new Array(); sty = new Array(); j = 0; for (i = 0; i < no; ++ i) { dx[i] = 0; xp[i] = Math.random()*(doc_width-50); yp[i] = Math.random()*doc_height; am[i] = Math.random()*20; stx[i] = 0.02 + Math.random()/10; sty[i] = 0.7 + Math.random(); if (ns4up) { // layers if (i == 0) { document.write("<layer name=\"dot"+ i +"\" left=\"15\" top=\"15\" visibility=\"show\"><img src=\""+ ballon[j] + "\" border=\"0\"></layer>"); } else { document.write("<layer name=\"dot"+ i +"\" left=\"15\" top=\"15\" visibility=\"show\"><img src=\""+ ballon[j] + "\" border=\"0\"></layer>"); } } else if (ie4up||ns6up) { if (i == 0) { document.write("<div id=\"dot"+ i +"\" style=\"POSITION: absolute; Z-INDEX: "+ i +"VISIBILITY: visible; TOP: 15px; LEFT: 15px; width:1;\"><img src=\"" + ballon[j] + "\" border=\"0\"></div>"); } else { document.write("<div id=\"dot"+ i +"\" style=\"POSITION: absolute; Z-INDEX: "+ i +"VISIBILITY: visible; TOP: 15px; LEFT: 15px; width:1;\"><img src=\"" + ballon[j] + "\" border=\"0\"></div>"); } } if (j == (ballon.length-1)) { j = 0; } else { j += 1; } } function ballonNS() { for (i = 0; i < no; ++ i) { yp[i] -= sty[i]; if (yp[i] < -50) { xp[i] = Math.random()*(doc_width-am[i]-30); yp[i] = doc_height; stx[i] = 0.02 + Math.random()/10; sty[i] = 0.7 + Math.random(); doc_width = self.innerWidth; doc_height = self.innerHeight; } dx[i] += stx[i]; document.layers["dot"+i].top = yp[i]+pageYOffset; document.layers["dot"+i].left = xp[i] + am[i]*Math.sin(dx[i]); } setTimeout("ballonNS()", speed); } function ballonIE_NS6() { for (i = 0; i < no; ++ i) { yp[i] -= sty[i]; if (yp[i] < -50) { xp[i] = Math.random()*(doc_width-am[i]-30); yp[i] = doc_height; stx[i] = 0.02 + Math.random()/10; sty[i] = 0.7 + Math.random(); doc_width = ns6up?window.innerWidth-5:document.body.clientWidth; doc_height = ns6up?window.innerHeight-5:document.body.clientHeight; } dx[i] += stx[i]; if (ie4up){ document.all["dot"+i].style.pixelTop = yp[i]+document.body.scrollTop; document.all["dot"+i].style.pixelLeft = xp[i] + am[i]*Math.sin(dx[i]); } else if (ns6up){ document.getElementById("dot"+i).style.top=yp[i]+pageYOffset; document.getElementById("dot"+i).style.left=xp[i] + am[i]*Math.sin(dx[i]); } } setTimeout("ballonIE_NS6()", speed); } if (ns4up) { ballonNS(); } else if (ie4up||ns6up) { ballonIE_NS6(); } // End --> </script>

Kopieer deze ballonnen en plaats ze in dezelfde directory als je pagina:
