I have been looking into responsive design using Omega subthemes. It seems very powerful when combined with the context and delta modules. However, I am having difficulty understanding how to selectively remove parts of a page in a responsive website. When I say remove, I don’t mean hide, but actually prevent the specified content from rendering (that way a mobile browser doesn’t have to waste time downloading content which is never displayed).
Omega provides the ability to apply different CSS to a page based on browser size (by using media query tags). Delta and context modules to be used to change the arrangement of page elements, or even remove page elements, based on certain conditions. However, I have not been able to work out how to combine the two.
For example, is it possible to, not only apply different CSS at different browser window sizes, but also prevent certain page content being rendered at the same time?
I have not been able to find any information on this. I am guessing since page content is rendered on the server side and media queries work on the client side, that it is probably not possible. I would be interested to know if anyone has any ideas on how I could achieve this.
You should take a look at the Context Breakpoint module. It allows you to set Context conditions based on the end-users browser size, aspect ratio and resolution.
