Is it feasible to developers specify when the contents of the web page stack by responsive design? So for example if you are in 1200 x 1800 resolution, you are in the following display:
[A] [B]
However, if you are in 1000 x 1800 resolution, your display automatically in the following stack format by the virtue of Twitter Bootstrap's responsive functionality (I use Bootstrap 3):
[A]
[B]
However, is it feasible for developers specify when the responsiveness occurs - for example, when the resolution is less than 1100 x 1800, the above stack occurs - and if it's feasible, how can I specify it?
I use Bootstrap, HTML5, CSS3 as well as node.js, but I think node is irrelevant in this case.
I use Google Chrome, and don't care about how the other browsers react to the change.
Thanks.
