Responsive web designs mean the ability
of websites to open and function smoothly on multiple devices. With
the increasing popularity of smartphones, tablets and other mobile
devices, web developers have quickly understood the importance of
responsive website designs. Today it is no longer a matter of choice
that websites need to be responsive, it is compulsory. To develop a
responsive website, it is important that designers know how to use
frameworks, grids to their advantage. They also have to be well aware
of at least a few standard screen sizes. It is also not uncommon for
developers to test their websites in multiple devices during the
development phase.
