History
History
• May 2010 article in A List Apart. Described the theory and
practice of responsive web design in brief 2011 book titled
Responsive Web Design. Responsive design was listed as #2 in
Top Web Design Trends for 2012 by .net magazine after
progressive enhancement at #1.
Definition
• Responsive Web Designing is a small principle of scaling a size of
screen in percentages, works based on simple principles of Grid
Layout’s, Flexible Images, Flexible Video’s and simple css3 and
extension of Media Queries
Why We Need RWD….?
The total number of people using the web on mobile devices is set to surpass desktops by 2015.

How do we cope with users having a range of different size devices?
1.Separate UI
Design
2.Separate URL
3.Images
4.Video’s
5.Money
Mobile Web Sites
Very expensive.
Native App’s
->methods are not completely reliable unless used in conjunction with a device capabilities database->HTML and CSS features are supported

How it works…….?
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.

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 Grid Layouts
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

Img {
width:100%; }
}
#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.
A lightweight, easy-to-use Jquery plugin for fluid width video embeds

jQueries a fast, small, and feature-rich javaScript library. It makes things like html 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?

supported by 70-80% of
today’s web devices
