Re: Single Page Applications

The term responsive is thus ambiguous and can be confusing if we don't specify the meaning intended.

Thanks for raising the point. It jogged my memory about how
"responsive" was described at http://getbootstrap.com/ which is inline
with the definition you provided.

The definition I provided previously, pertaining to the performance of
the page, was borrowed from an Angular JS tutorial. I think
"responsive" is a necessary attribute of web sites and web
applications, whether it pertains to performance, or whether it
pertains to adapting the page to the size of the screen.

While viewing http://www.nasa.gov/ in my iPad, the layout changes,
depending on whether viewed in landscape or portrait mode. More
specifically, the menu bar disappears when viewed in portrait mode.
Bootstrap is known for implementing behaviors like that.

Are JavaScript and CSS frameworks necessary to adapt pages to screen
dimensions? Are removing or hiding visual components from the display
a good thing? Or should visual elements just wrap?
