  1. Responsive Design

  2. In Class Today • Review Course Project • Review Homework Assignment • Responsive Design Presentation • In Class Assignment

  3. Overview • What is Responsive Design? • Media Queries • Variable Width design • Trending Development Frameworks • In class assignment

  4. Responsive Design 101 • Pretty basic • Write CSS for different browser sizes, device capabilities and aspect ratios using ‘Media Queries’ • Media Queries will query the media you are using and use the appropriate CSS (respond) in real-time (without reloading the page)

  5. Viewport • Meta tag • Used to control the viewport's size and scale • Accepts either a positive integer or keyword

  6. Viewport • Chapter 2 – Examining the mobile viewport & Controlling viewports

  7. Media Queries = Expression • A media query is a logical expression that is either true or false • The CSS associated with the media query expression is only applied to the device if the expression is true.

  8. Media Queries • Allow web developers to change our layouts to suit the exact need of different devices - without changing the content. • a CSS3 extension to media types that gives us more control over rendering across different devices

  9. Initializing Media Queries • @media rule • @import rule • Separate style sheet

  10. Media Types

  11. Logical Operators • Help build powerful expressions • Three different logical operators: • And • Not • Only • Syntax link rel=“stylesheet” href=“style.css” media=“[AND| NOT] screen[ONLY] (expression)”

  12. AND Operator • Allows an extra condition to be added • Comma separated, acting as an unspoken or operator • Example:

  13. NOT Operator • Negates the query, specifying any query but the one identified. • Example:

  14. ONLY Operator • Hides style sheets from older or non-conforming user agents • Ignored by conforming user agents

  15. Browser Support • Internet Explorer: 9.0+ • Firefox: 3.5+ • Chrome: 4.0+ • Safari: 3.1+ (a bit buggy until 4.0, however) • Opera: 9.5+ • iOS: 3.2+ • Android: 2.1+ • Windows Phone: 7.5+ (Mango) • Blackberry: 4.7.1+

  16. Height & Width Media Features • One of the most common media features • Used with: height, width, device-height, and device-width • Height and width media features base off the height and width of the viewport rendering area

  17. Media Query Breakpoints • 320px - Mobile portrait • 480px - Mobile landscape • 600px - Small tablet • 768px - Tablet portrait • 1024px - Tablet landscape/Netbook • 1280px & greater - Desktop

  18. Media Queries • Chapter 2 – Understanding Media Queries and Creating breakpoints with media queries

  27. Mobile First • Popular technique with using media queries • Saves user from having to load styles for desktop version

  28. Fluid/Flexible Layout • A layout based on proportions rather than absolute • Built using relative length units, most commonly percentages or emunits • Relative lengths are used to declare common grid property values such as width, margin, or padding

  29. Flexible Layout Formula

  30. Fixed vsFluid/Flexible Fixed Fluid/Flexible

  31. Using Fluid Grids • Chapter 2 - Using Fluid Grids

  32. Advantages of using Grids • Great for content-rich sites • Device-friendly • Enhanced stability • Better engagement • Unmatched flexibility

  33. Disadvantages of Using Grids • Restricted creativity • Lack of dynamic appeal • Steep learning curve • Not fit for all sites

  34. What is a Responsive Framework? • A standardized set of concepts, practices and criteria for dealing with a common type of problem, which can be used as a reference to help us approach and resolve new problems of a similar nature. • Package of files and folders of standardized code (HTML, CSS, JS documents etc.) which can be used to support the development of websites

  35. Trending Grid Frameworks • 960 Grid System (960.gs) • Unsemantic– (unsemantic.com) • Skeleton (www.getskeleton.com) • Skeleton for Wordpress(themes.simplethemes.com/skeleton) • Bootstrap (getbootstrap.com) • Compare (responsive.vermilion.com/compare.php)

  36. Choosing the Right Framework • Speed of installation • Ease of understanding • Options • Integration with other systems • Best long-term support

  37. Advantages of Frameworks • Speeds up the mock-up process • Clean and tidy code • Solutions to common CSS problems • Browser compatibility • Learn good practices • Having a single procedure to resolve common problems makes maintaining various projects more straightforward. • Helpful in collaborative work

  38. Disadvantages of Frameworks • Mixes content and presentation • Unused code leftover • Slower learning curve • You don’t learn to do it yourself

  39. Flexible Images and Media

  40. Flexible Images and Media

  41. Flexible Images • Chapter 2 – Making Images Responsive & Examining the future of responsive images

  42. RWD vsOther Options • Native Apps • A native application (native app) is an application program that has been developed for use on a particular platform or device. • Mobile-Specific Website • A scaled down version of your site with any unnecessary content removed to improve its functionality and load speed on mobile devices.

  43. Native Apps Pros Cons • Can provide a slick user experience • Can more easily access device features (camera, GPS, etc.) • Available for offline use • Very expensive • Hard to do well • Which platforms do you support? • Your users (probably) don't want a native app • You still need a website

  44. Mobile-Specific Websites Pros Cons • Easier to optimize for speed • More freedom to create a unique mobile experience • Can more easily target less advanced devices, like feature phones • Have to deal intelligently with redirects • Ignores tablets for the most part • Tends to offer an incomplete experience

  45. Responsive Design Pros Cons • Only have to maintain a single website • Don't need to deal with mobile-specific URLs • Addresses a wide multitude of devices: phones, tablets, desktops, etc. • More difficult to optimize properly for specific devices (for example, phones might get desktop-sized images) • Testing, testing, and more testing

  46. Advantages of Responsive Design • Save Money • Save Time • Improved SEO • Better Performance • Wide Browser Support
