Definition
? Responsive Web Designing is a small principle of scaling a size of

Layout��s, Flexible Images, Flexible Video��s and simple css3 and
extension of Media Queries

Basic Principles
1.The Flexible Grid Layouts
2.Flexible Images
3.Flexible Videos
4.Media Queries
Well, We need only 4 ingredients for this��.

The fluid grid concept calls for page element
sizing to be in relative units like percentages,
rather than absolute units like
pixels or points.
Flexible Grid Layouts
In graphic design, a grid is a structure
(usually two-dimensional) made up of a series
of intersecting straight (vertical, horizontal,
and angular) or curved guide lines used to
structure content

target �� context �� 100 = percentage
target- Require Amount Of Space.
context- Total Page/Grid We Have

MENU
215/960*100=22.395833333%
CONTENT AREA
685/960*100=71.354166666%
INSET SLIDEBAR
215/685*100=31.3868613333%
20px margin for the Menu and Content
Area:
20/960 �� 100 = 2.0833333333%
20px margin for the Inset Sidebar:
20/685 �� 100 = 2.9197080292%

Flexible images are also sized in
relative units, so as to prevent them
from displaying outside their
containing element
First discovered by designer Richard Rutter, this one rule immediately provides an
incredibly handy constraint for every image in our document. Now, our img element
will render at whatever size it wants, as long as it��s narrower than its containing
element. But if it happens to be wider than its container, then the max-width:
100% directive forces the image��s width to match the width of its container
Flexible Images

Flexible Images

Img {

}
}
#container{
width:600px;
margin-right:auto;
margin-left:auto;
}
#left-column{
width:420px;
float:left;
background:red;
}
#right-column{
width:180px;
float:right;
background:green;
}
@media screen and(max-width:
590px)
{
#container{
width:100%; }
#left-column{
width:70%;
background:red;}
#right-column{
width:30%;
background:green;
}
img{
width:100%; } }

Flexible Video
Similar situation as images, but maintaining proper proportions is a problem.

document traversal and manipulation, event handling, animation and Ajax much simpler
with an easy-to-use API that works across a multitude of browsers

Flexible Video
img, embed, object, video
{
width:
100%;
}
.video iframe,
.video object,
.video embed {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
}

Media Queries
Media queries allow the page to use different CSS style rules based on characteristics of
the device the site is being displayed on, most commonly the width of the browser.
Media Queries is a CSS3 module allowing content rendering to adapt to conditions such as screen
resolution (e.g. smartphone vs. high definition screen).
When a media query is true, the corresponding style sheet or style rules are applied, following the normal
cascading rules.
Here is a simple example:
@media screen and (min-width:500px) { ... }

Media Queries
@media all and (max-width: 1024px) {...}
Common Media Query Conditions
min-�\device-�\width or min-�\device-�\height
Applied if the device screen is equal to or greater than this value
max-�\device-�\width or max-�\device-�\height
Applied if the device screen is equal to or less than this value

What web browsers support CSS3 media
queries?

BROWSER SUPPORT
Responsive design is
supported by 70-80% of
today��s web devices
