Creating a online webpage designer using jquery, is it hard?

I want to create an online web page editor using jquery.

How complicated is this type of feature? (yes I know its hard to answer this)

From wh开发者_StackOverflow社区at I can tell, you are simply referencing the various elements on the page and when a user selects a color in a colormap, you simply then cycle through the elements on the page that match a particular set of id's or classes and modify them.

I would also need to use jQuery live as new elements in the DOM will be added/removed.

Am I making it easier than it is?
