Responsive Web Design

A Flexible Grid-Based Layout

Font Size

  • Don`t use no pixel.
  • Set body size to 100%, typically the browser’s default type size of 16 pixels.
  • Set h1, h2 size to em, target ÷ context = result, such as 24 ÷ 16 = 1.5, the context is container.


  • The context is container, target ÷ context = result.


  • The context container, target ÷ context = result.


  • The context is current element, target ÷ context = result.

Flexible Image and Media

Image Tag

  • max-width: 100% - let browser automatically resize image
  • overflow: hidden - cropped to fit inside its container

Tiled Background Image

  • background-position - transition image base on percentage, target ÷ context = result, image dimension not change

Background Image

  • background-size ( CSS3 ) - resize background image

Retina Image

  • image tag with explicit width and height like 50×50, provide a image with size of 100×100
  • base on device resolution provide different images, Easy retina-ready images using SCSS

Media Queries

  • ViewPort <meta name=”viewport” content=”initial-scale=1.0, width=device-width” /> width is window view size, device-width is device size.
  • Each query still begins with a media type ( screen ), drawn from the CSS2.1 specification’s list of approved media types. (Like all, screen, print ).
  • Immediately after comes the query itself, wrapped in parentheses: ( min-width: 1024px ). And our query can, in turn, be split into two components: the name of a feature ( min-width ) and a corresponding value ( 1024px ).
  • Use max-width property for large screen to force a solid width, Experimenting with responsive design in Iterations.
  • IE8 and below is not support.
  • Media Queries for Standard Devices.


  • Photoshop a page mockup, typically a desktop-centric design.
  • Turn mockup into html, change browser window size to test.
  • Test on devices and laptops to gather issues.
  • Change page mockup, treat it as a blueprint to design other pages.
