How to make Bgcolor changer save choice usig cockies ??

[Dormilich]

for java cookies you’d need Java (that’s actually a different language), but I’m not sure whether Java applet have their own cookies …

however you have the choice to store data in regular cookies or the new Web Storage using JavaScript.

I haven’t used cookies for a while but IIRC setting data works by

document.cookie = "key=value";

reading is a bit more complicated as you get all key-value pairs as string. [more info]
