Until
recently,
the
size
of
the
screens
of
computers
getting
bigger
every
year.
For
web
designers,
it
«
enough »
to
expand
the
interfaces
over
time.
Then
came
the
iPhone
and
other
Smartphones,
the
iPad,
tablets
and
other
Notebook,
which
are
gradually
revolutionizing
the
Internet
and
its
uses.
A
major
challenge
for
web
designers
now
is
to
build
an
interface
readable
on
small
screens,
remain
enjoyable
on
large
one,
taking
into
account
the
specific
constraints
to
each
medium
(navigation
with
mouse
or
finger),
in
order
to
provide
the
best
user
experience
as
possible.
One
answer
is
the
Responsive
Web
Design.
Ethan
Marcotte
was
the
first
to
wrote
the
principles
in
an
article
published
in
May
2010.
Principles
which
can
be
summarized
in
two
words:
flexibility
and
responsiveness
and
are
based
on
three
basic
elements:
-
grids
that
can
build
interfaces
using
a
variable
number
of
columns
in
which
are
inscribed
contents
-
flexible
images
where
size
and
layout
are
set
in
response
to
the
screen
size
-
media
queries
that
can
detect
which
medium
is
used
(or
rather
the
size
of
the
screen)
and
allow
specific
design
(size,
shape,
position
of
elements,
...)
This
technique
is
still
young
enough
and
uses
the
latest
web
standards:
HTML5
and
CSS3
(especially
for
media
queries),
and
requires
careful
consideration
from
the
designer's
site
on
how
to
redistribute
items
based
on
resolution
of
the
screen,
or
appearing/disappearing
of
some
elements.
The
Responsive
Web
Design
offers
therefore
new
possibilities
for
website
design
and
provides
tools
and
methods
to
give
for
each
device
the
best
design.
A
Responsive
Zenphoto
theme
After
creating
two
"static"
themes
for
Zenphoto
and
regularly
browsing
on
the
Net
with
a
SmartPhone,
I
see
now
the
benefits
of
a
photo
gallery
that
fits
the
media.
After
seeing
the
excellent
theme
zpSkeleton,
I
started
a
new
adventure
and
I
am
working
on
a
new
Responsive
Zenphoto
theme.
I
hope
to
quickly
achieve
a
beta
that
I
will
show
you.
