Where in CSS do I make changes to create a mobile responsive site?

What would it look like...??

I am trying to help a friend and I am a novice HTML person... I can get around but I ma not a pro yet...

Thx for your help

I would start from scratch as making a none responsive site responsive by altering the existing code will take way to long.
Either grab RLM or a responsive theme for the HTML editor from CC.

I am with Eric, best way is to start again.

If you have implemented CSS which is in a separate file to the HTML (as most CSS is) then it's actually not too hard to make the changes, especially if the HTML code of the is more of less the same at the top and bottom of the HTML.

Once I got to grips with how Responsive Layout is supposed to work it's rather straight forward. The hardest part was getting the site layout design done but with the HTML Editor I just did a massive series of copy and pastes, test, fix and test again and I was able to get my site, which is over 200 pages, updated in a weekend.

The hardest part was getting the CSS written for the changes and once that was done the actual changes were trivial in comparison.

The book that I used to help me was from Amazon and I do recommend it wholehearted. You don't need to read all of it, just until the bit where he prattles on about resizing graphics which is just the first half of the book.

Once I got to grips with what's required, wrestled with the CSS it was easy to do with HTML Editor.

I am no website pro at all. I have a simple (but large) website and all of the clever work is in the back end coding (it's mostly .asp) but the website isn't that of a pro at all. So, if I can do it then I am sure that you can.

If you are set on making the existing site responsive, then you could start by changing all the container widths from px to %
Next, the font sizes from px to either % or em.
You need to make your images resizable. I'm a bit short of time right now, so if you want to go this route, someone else will have to help, or you'll have to wait until this evening (CET).

There is a bit more to it, like floats etc.

But doing as suggested by others above is a much more comfortable way of changing the site.

Suzie,

Whatever route you ultimately choose to take, I'd suggest you start out reading this paper:
http://alistapart.com/article/responsive-web-design
(OK, I know it's five years old, but it has stood the test of time, and it's a quick, easy read! )

Then consider this book:
