OUR CLIENTS

TennantsDistribution

One billion smartphones in use One half of all local searches via mobile devices Average users can spend 2.7 hours per day socialising on a

mobile device Over a third of all traffic on handheld mobile/tablet device Mobile (tablet and smartphone) traffic share increased

from 23% to 37% in 2013 Desktop traffic share decreased from 77% to 63% in 2013 Mobile and tablet web browsing set to overtake

traditional desktop usage in 2014

MOBILE DEVICE SHARE

AVERAGE UK MOBILE SHARE - 2013

Traditionally, websites always designed from desktop experience first

Mobile and tablet was a secondary goal Growing trend that mobiles considered first

and then work up to desktop experience “Mobile First” web-design quickly becoming a

widely-adopted design principle There are considerations such as what type of

user will be viewing your site

MOBILE FIRST

Graceful degradation is the idea that the designer starts with the desktop website and scales the site back to gradually remove content and features as the screen size becomes smaller.

GRACEFUL DEGRADATION

Progressive enhancement is the idea of starting with the best that can be achieved on a mobile device, designing a site that is the best it can possibly be for the smallest devices and then gradually enhanced for larger, desktop, screen sizes.

PROGRESSIVE ENHANCEMENT

Same goal, different results? GD may result in severely watered-down mobile version so

reality is to consider mobile as part of your desktop design PE can let you add/improve as you can which ties in with

Agile development (sprints which improve functionality) Performance can suffer from a GD approach as mobile can

end up loading desktop content which it then ignores. PE approach tends to produce leaner implementations

Foundation and Bootstrap are now mobile-first

DEGRADATION VS ENHANCEMENT

Aimed at crafting sites to provide an optimal viewing experience,

Easy reading and navigation with a minimum of resizing, panning, and scrolling,

Targets a wide range of devices (from mobile phones to desktop computer monitors),

A responsive site adapts its layout to the viewing environment by using:• Fluid, proportion-based grids, • Flexible images, • CSS3 media queries (@media rule extension).

RESPONSIVE DESIGN

Lower development costs (single site) Easier (cheaper) to maintain and support Content is easier to create and administer Simpler deployment Reduced hosting and resource utilisation

COSTS

Google recommends the use of Responsive Design for creating mobile websites:• Single content URL is easier for users to interact with,

share, and link to• Single content URL helps Google algorithms assign

indexing properties for content• No redirection needed for users to get device-

optimised view, which reduces loading time• Saves resources for site and Google crawlers• Single domain prevents SEO dilution across multiple

sites

SEO

Dedicated mobile sites may have more scope to meet requirements of mobile users

In practice, responsive design can usually meet all requirements

Many frameworks available to speed up site design and improve/standardise user experience

DNN offers a device-aware content preview feature Consolidated view – the ability to be device

agnostic when presenting content is implicit

USER EXPERIENCE (UX)

A responsive design may offer lower-performance than a dedicated mobile site as desktop elements of a page may be downloaded by a mobile device

Mobile sites may be more applicable for users in countries where Internet access speed is an issue

Dedicated mobile sites can be much more efficient in terms of:• Data transfer• Number of associated page requests

PERFORMANCE

Typically a structure of files and folders of standardized code • HTML, • CSS,• JavaScript (e.g. mobile image sliders, mobile UX)

Known as front-end/CSS frameworks Faster to develop with than a custom solution

RESPONSIVE FRAMEWORKS

Bootstrap • Built at Twitter, • Managed via GitHub,• Offers large number of styles.

Foundation • Made by ZURB, a product design company in

California, • Features Interchange (HTML partials for device-

specific content – more later), • Fewer styles out of the box than Bootstrap.

POPULAR FRAMEWORKS

Mobile first HTML 5 Uses Normalize.css to improve cross-browser rendering

(support IE8+) Fluid grid system scaling up to 12 columns as

device/viewport size increases Sass (Syntactically Awesome Style-Sheets)

• Extends and compiles into CSS• Supports Mixins (for code reuse), variables (numbers, strings,

colours and booleans), arguments, nested code and selector inheritance

EXAMPLE - BOOTSTRAP

Lets you selectively load entire sections based on the client device type

Load different sections of your page for particular media queries

Load up mobile-friendly components on small devices, and more robust/heavier/feature-rich components for desktops

Images - only load larger resources for devices that can handle it.

FOUNDATION – INTERCHANGE

Gumby – built on Sass pre-processor Yahoo Pure – lightweight, no JS plugins –

great for the metro design of Windows InK – includes drag/drop support and MIT-

licensed icons Skeleton, Responsive Grid System, Base,

Compass, Fluid Baseline Grid, etc.

OTHER FRAMEWORKS

Bootstrap and Foundation have standard download packages with styles and JS to support lots of components

You don’t need to download them all! Get only the JS and CSS you need for your

web site to reduce bloat and page load times Design first and then customise the package

to suit your requirements

LEVERAGING A FRAMEWORK

9-month project 25+ websites Migrated from bespoke

platform to DNN Evoq Largest DNN Evoq project by

daily page views Dozens of load-balanced web

servers Worked with DNN Corp. core

team Case study

SPORTS DIRECT

Sister website of SportsDirect.com Same catalogue of products as

SportsDirect.com Previously no support for mobile devices

CASE STUDY - LILLYWHITES

www.lillywhites.com

Support for mobile devices provided via 3rd party service

No support for tablet devices Very expensive to rollout new websites Have to maintain multiple codebases New features developed on desktop not

available on mobile devices Large % of users accessed the site via mobiles

devices…

PROBLEMS & BRIEF

Cantarus Brief:

“Convert the Sport Direct codebase into a supportable, feature rich, fully-

responsive framework with support for mobile and tablet devices…”

PROBLEMS & BRIEF

Visitors should not be aware if it is a responsive site as apposed to dedicated mobile site

Huge challenge to maintain performance with addition of responsive framework & additional mark-up code

IMPLEMENTATION

3 distinct views:• Desktop, Mobile & Tablet

Full gesture support Geo-IP detection of user location Switch to desktop/mobile view

KEY FEATURES

Responsive SwitchHTML5 Geolocation API

Lazy-load images Use a CDN such as CloudFlare Mobile-first helps! Load menus asynchronously

• Over 2/3 of mark-up for Lillywhites Homepage was mobile & desktop menus

• Menus are loaded after the page loads to give users the feeling of fast load

PERFORMANCE

DEMONSTRATION

LILLYWHITES

Mobile set to overtake desktop in 2014 Choose your delivery vehicle – responsive design or

separate mobile/desktop sites Google recommends responsive design Responsive generally the cheaper and more desirable

approach Dedicated mobile site may still be the best choice Decide if mobile-first is your preferred approach - GD

vs PE Front-end/CSS frameworks for responsive design
