I am learning HTML5 and Bootstrap, I have my parent container(fluid) inside which I have 3 div, I always use the code of bootstrap class(col-md/xs/sm/lg) to show how the UI should be for different view-portal but how can I dynamically re-size these div using mouse drag over its borders? I mean like enlarging a image.
Also by increasing one div size the other two should dynamically re-size themselves within the container.
Is there any JS code which I can download? is there any thing to learn that might help me?
