Question

How to change the .page width value below, programmatically in the code behind page?

I need to set it based on the width of other elements on the page which keep changing based on user actions.

        .page
        {
            width: 1900px;
            margin: 0px auto 0px auto;
            position:fixed;
        }

How change that from c# code, what is the syntax for it?

You can do it with jQuery if you want to use jQuery –

<script type="text/javascript">
  $(document).ready(function() {
    $('.page').css('width', $('.otherElementClass').width()+'px');
  });
</script>
