The document discusses responsive web design, including its history beginning in 2010, the basic principles of using flexible grid layouts, images, and videos along with media queries to adapt designs based on screen size. Responsive design allows a single website to be accessed from any device by using fluid, proportional layouts and flexible media to provide the best possible viewing and interaction experience. New techniques like responsive design are necessary to accommodate the growing number of people accessing the web from mobile devices.

- 16. Basic Principles 1.The Flexible Grid Layouts 2.Flexible Images 3.Flexible Videos 4.Media Queries Well, We need only 4 ingredients for this….
- 17. 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
- 18. target ÷ context × 100 = percentage target- Require Amount Of Space. context- Total Page/Grid We Have Flexible Grid Layouts
- 19. Flexible Grid Layouts 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%
- 21. 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
- 22. Flexible Images file:///D:/edu/4.1/seminor/rw d/images/clagnut.com/sandbox /imagetest/index.html file:///D:/edu/4.1/seminor/rw d/rwd/clearleft.com/index.html 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%; } }
- 23. 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 http://fitvidsjs.com/ 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
- 24. Flexible Video img, embed, object, video { width: 100%; } .video iframe, .video object, .video embed { position: absolute; top: 0; left: 0; width: 100%; height: 100%; }
- 25. 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) { ... }
- 26. 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
