hi

i am new to javascript and i try to play around with it but i am stuck at the moment lol
hope that someone can help me check my code and tell me what is wrong with it

in the page the user can change the background color and the font family so when they open the website, the background and the font they selected is load back

<html>

<head>

<!--background color function-->
<script type="text/javascript">
function changeBackgroundColor(elem, dropper) {

</script>

<!--font family function-->
<script type="text/javascript">
function changeFontFamily(elem, dropper) {
  document.getElementById(elem).style.fontFamily = dropper.options[dropper.selectedIndex].value;
}
</script>

Hi there! Heres the conclusion to your 1st query regarding changing the looks of your page.
This script wil load specific themes' using different style sheets depending on the selection being provided by the user and of course with the help of cookies. It's a compact script, hope youll enjoy this...

if i have lots of option like change the background color : blue, red, black, green and fontfamily : tahoma, arial, verdana fontcolor: red,green, blue

that will be mean that i have to make css file for each possibility that will happen? like blue bgcolor, tahoma, red font then blue bgcolor, arial, green font

howdo you make one cookies with lots of different name?

Just a sets of theme so you dont have to choose for the font, font sizes, color, bgcolor and so on...
Ok assuming that i have the following rules in the "black.css"

body {
     borderd: none;
     backgroud-color: #000;
     color: #ccc;
     font: normal 12pt/105% Georgia, Arial, sans-serif;
}

You can provide themes as many as you want. The ones you use depends only on your design capabilities and imagination.

this is my latest code

there are several option for user

background color = red, green, blue
font color = red, green, blue, black
font type = arial, times, verdana, tahoma
font size = small, medium, large, x-large, xx-large

lets assume that someone want to choose:
background color = red
font color = green
font type = verdana
font size = medium

that is mean that i have to make css page that can handle those requirements

what about if that person want to change the page like:
background color = green
font color = blue
font type = times
font size = xx-large

that is another page which is mean another css file, right

so there gonna be lots of css then to meet all the possibilities that can happens

What do you think?

Oh, and thank you for the cookies code
it works perfect
