<script>
// to change the color of an object.
function changeColor(){
x=document.getElementById("Id1");
x.style.color="Red";
}
// to change the content of an object.
function changeContent(){
y=document.getElementById("Id2");
y.innerHTML="Hi, you have changed the contents using Java Script successfully!";
}
</script>
</HEAD>
<BODY bgcolor="AntiqueWhite">
<h1 ><center>Welcome Page</center></h1>
<p id="Id1">It is test 1.</p>
<p id="Id2">It is test 2.</p>
<button type="button" onclick ="changeColor()">

</button><br/><br/>
<button type="button" onclick ="changeContent()">
