Make use of the Jquery in the HTML page and do change the CSS class based on the condition you choose...in $(document).ready() ..allows to achieve you task easily..

Your question isnt really specific enough to give you a whole answer. However.

1. as HTML is only text, download the HTML within your app, either extract the bits you want, or, look for the bits you need to change, such as body colour, or CSS.. If its CSS, replace it with your own.

2. Just because there are 40k files, doesnt mean you cant change them - if its accessible and feasible, then you can always do it. Even if you write a utility to do it for you. Such as.. inserting a comment section so you can easily extract sections from pages.

3. If you have a specific question, show an example, your question and explain a little of what you tried. You will get better quality answers.

It sounds a design issue rather than a technical.

You should break down those 40 KB files into smaller parts using some of these technologies:

1. Master Pages
2. Server Controls
3. Caching
