Online news in the “mobile first” era
The web is so old-fashion
We must have app, it’s “cooler”
How newspapers respond?

YESTERDAY TODAY
CHALLENGE FOR CODER AND “PRODUCT-ER”
AS CODERS• Code and
maintain different versions of the same product
AS “PRODUCT-ER”• Make sure all
versions are in synced
• Provide consistent and accurate analytics
THE PROMISE LAND FOR US WOULD BE…
DESIGN ONCE, CODE ONCE VIEW ANYWHEREBEFORE WE GO TO THAT LAND…
Introduce
zing news version 3
Demo time - ONE design FIT ALL screen
Benefit of having one version
• We no longer have to maintain different version. Update to the desktop automatically reflect on the mobile version.
• Consistent sharing experience. This is difficult in the case we have to redirect to a different domain on mobile
• Better pageview tracking across devices.The new GA code even allow support tracking visitors across devices.
The future of web design
Responsive design
What is responsive design?
• Screen size• Time of the day• Location• Pointing method
Design that automatically adapt to the viewer’s viewing environment.
HOW TO MAKE REPONSIVE DESIGN?
“There is a media query for that”@media tv/print/projection/3d-glasses
@media all and (orientation:landscape)
@media screen and (resolution: 96dpi)
@media screen and (min-width : 1224px)
@media all and (-webkit-min-device-pixel-ratio: 2)
@media all and (device-aspect-ratio: 4/3)
You can mix them together too@media screen and (device-width: 768px) and (device-height: 1024px) and (orientation:portrait)
Not all supported by all browsers, but luckily they are universally supported in all mobile browser
CODE FOR DESKTOP FIRST
Always design & code for the most popular case first.
In our case, it’s desktop screen. Most of our visitors come from desktop:• On desktop, IE6 & 7 are still used by
many• The “standard” screen size for desktop
browser is 1024x768
CSS styles for most popular
case
Media Query override for different screen size
Styles.css
Tips when code for desktop
Overide the default box model of browser* { -moz-box-sizing: border-box; -webkit-box-sizing: border-box; box-sizing: border-box; }
If you design fixed layout for the desktoop, in CSS convert all width in pixel to percentage relative to the parent element. The only element with pixel width is the most outer one
#wrapper {width: 960px;}
#wrapper .left {width:25%;margin-right:0.625%;} /* = 240px & 6px */
#wrapper .center {width:52.08%;margin-right:0.625} /*= 500px & 6px */
#wrapper .right {width:21.667%;} /* = 208px */
As always, simplify your HTML code as much as possible. The less elements, the less you have to do later.
Tips CODING FOR DESKTOP … (CONT’D)
For images element, define the frame and use background css attribute to have picture fill the frame
HTML<article>
<p class=“cover” style=“background-image:url(cover.jpg);”>
<img src=“cover.jpg” … />
</p>
</article>
CSSarticle {width: 50%; height:100px;}article .cover img {display:none;}article .cover {width:40%;height:100%;background-repeat:no-repeat; background-size:cover; background-position: 50% 50%;}
deciding at which size your design
would respond to
3200 480 768 1024
Go to Google Analytics and see what screen size are the most popular ones. As a rule, pay focus to optimize for screen sizes used by more than10% visitors
iPhone (portrait)Small smartphone
iPhone (landscape)Bigger smartphone
7 inch tablet(i.e. Kindle) iPad (portrait) Desktop
iPad (Landscape)
OVERRIDING YOUR BASE STYLE
Once decided on the screensize, overriding the base CSS using media query. Sorting your media query so that you have to use the least overriding code:- CSS for standard 1024px width normal css (no media query), base for all styles
- @media screen and (min-width: 1200px) 1200px and bigger
- @media screen and (max-width: 1023px)iPad & all mobile devices
- @media screen and (max-width: 767px) 7 inch tablet and smaller
- @media screen and (min-width:600px) and (max-width: 799px)7 inch tablet only
- @media screen and (max-width: 599px)smartphone
TIPS FOR OVERRIDING CSS IN MEDIA QUERY
- Remember to define the viewport in header<meta name="viewport" content="width=device-width,initial-scale=1.0, maximum-scale=1.0, user-scalable=no"/>
- Use screen-width insteads of device-width
- Depending on how you define font-size, you might need to change font size on different screen so that text can easily been read.
- In responding to smaller/bigger screen size, do show/hide unnecessary element or redefine the grid.
- Make text link big enough so that it “touchable”. Always test your design on real device.
DIMENSION EXTENSION FOR CHROME
conclusion
Responsive design is the future
• Responsive design is not difficult. XHTML/CSS coders can use it without much learning.
• It’s require just a bit of thinking on the designer/coder part but in exchange reduce the cost of maintaining different versions
• If you have a website and want a mobile version of it with the same content, then responsive design is the way to go
• Obvious cases where responsive design is preferable beside news: e-commerce, banking
EVERY WEB DESIGNER SHOULD BEGIN GETTING FAMILIAR WITH RESPONSIVE DESIGN TECHNIQUE. IT’S THE FUTURE.
FOR PRODUCT MANAGER HIRING NEW WEB DESIGNER, REMEMBER TO ASK IF HE/SHE KNOW HOW TO CREATE RESPONSIVE DESIGN (OR AT LEAST KNOW WHAT IT IS)
