title: how to: dynamically switch css page
body: <p>I am working on a webpage for an embedded device where the server storage space is very limited. I want the user to be able to switch between day mode and night mode viewing of the webpages. To do so I would like to just load the page using a different webpage with a button is clicked. I don't want to have two copies of every page because I don't have enough space. Is there a way to switch to a different css page or load the css dynamically somehow? I can only use html and javascript. No PHP or asp.net.</p>
