Is it possible to implement Twitter Bootstrap Framework to a existing website?.. My client want's this to just viewable to mobile, though I want it more challenging so I'm thinking it to be a responsive site.. if not possible, what would be your suggestion on how should I do it?.. Maybe I'll be make it to detect the screensize then call a css to implement, correct me if I'm wrong, haven't tried and made one.
I would like to suggest Twitter Bootstrap.. just get that framework from github and take your time to implement with there responsive layout
Modifying an existing site to use bootstrap would be difficult. If you just want to use a couple controls here and there (like a dropdown, or tooltip, etc) then it would be easier. Bootstrap has its own set of classes that you apply to divs. So you would have to change a lot of your CSS structure to use the bootstrap styles. If you're just using it for the mobile-only version of the site, then go for it. As you would be writing all of the CSS and html from scratch anyway. Responsive is ok, but it can mess with your layout as the user resizes the browser.
