I know how to use that. But I don't know how to put this code in

<SCRIPT language="JavaScript">var rainbowcount=(rainbowcount+1); document.write("<span id='rain"+rainbowcount+"'>"); </SCRIPT>

I've tried to put like this and it's not working

.rainbow {
color: red; font-weight: bold; <SCRIPT language="JavaScript">var rainbowcount=(rainbowcount+1); document.write("<span id='rain"+rainbowcount+"'>"); </SCRIPT>
}
