META VIEWPORTDefinition: A phone browser’s visible screen areaWhat it looks like:

initial-scale=1 , maximum-scale=1 Renders the page 100% user-scalable=yes Allows user to zoom
MEDIA QUERIES
Definition: CSS3 module to define styles for screen and print media typesWhat it looks like:
@media screen (min-width: 700px) and (max-width: 800px), handheld and (orientation: landscape) { ... }
Purpose: Tailored CSS for multiple viewport sizes and devicesFeatures:
(min-width: 700px) and (max-width: 800px ) Renders for screen with this size viewport
Screen, Handheld Adjusts for screens and for handheld devices
USING AN ONLINE TUTORIALSTEPS WITH CODE HANDOUT
1. Add a Meta Viewport <meta name="viewport" content="width=device-width, initial-
scale=1, maximum-scale=1">
2. For CSS: Use percentages rather than fixed widths
3. Add multiple Media Queries for different screen sizes: @media screen and (max-width: 600px) { … }
THAT WAS A BASIC EXAMPLE It will probably take a lot of time and testing to
make sure your site is responsive across all platforms
A NOTE ON HTML5THE FLASH KILLER & WHY YOU SHOULD USE IT
HTML5 = HTML + CSS + JS Full mobile/cross browser
support Meta Tags:
Viewport Full screen browsing mode Add as Home Screen Icons
Your Website ~ Native App! Better User Interactions
Cleaner Code (Ex: Class/IDs become tags, one line for animations)
<!DOCTYPE HTML>
