Template customizer

Hi,

In many templates here there is a template customizer toolbar, where you can for example change color of background or font even all presets can be loaded. My question is – do i have write this kind of script by my own or there are some solutions you use? I’m asking about html template not wordpress themes.

i would be thankful for any information.

it is demo purpose mostly, in order for you to change background etc you need to slightly change css or sometimes already provided with the download. in short not much of scripting work is required.
