On this page I explain a simple DHTML example script that features invisibility, moving and the changing of text colour.?

Example?
Test TextMake test text invisible.?
Make test text visible.?
Move test text 50 pixels down.?
Move test text 50 pixels up.?
Change colour to red.?
Change colour to blue.?
Change colour to black.?
Change the font style to italic.?
Change the font style to normal.?
Change the font family to 'Times'.?
Change the font family to 'Arial'.?

The script?
The scripts work on this HTML element:?

<DIV ID="text">Test Text</DIV>

#text {position: absolute;?
top: 400px;?
left: 400px;?
font: 18px arial;?
font-weight: 700;?
}?

These scripts are necessary for the three effects:

var DHTML = (document.getElementById || document.all || document.layers);

function getObj(name)?
{?
if (document.getElementById)?
{?
this.obj = document.getElementById(name);?
this.style = document.getElementById(name).style;?
}?
else if (document.all)?
{?
this.obj = document.all[name];?
this.style = document.all[name].style;?
}?
else if (document.layers)?
{?
? this.obj = document.layers[name];?
? this.style = document.layers[name];?
}?
}?

function invi(flag)?
{?
if (!DHTML) return;?
var x = new getObj('text');?
x.style.visibility = (flag) ? 'hidden' : 'visible'?
}?

var texttop = 400;

function move(amount)?
{?
if (!DHTML) return;?
var x = new getObj('text');?
texttop += amount;?
x.style.top = texttop;?
}?

function changeCol(col)?
{?
if (!DHTML) return;?
var x = new getObj('text');?
x.style.color = col;?
}?
