FRAMEWORK

as BASIS

Bootstrap

<div class="container-fluid">

<div class="row">

<div class=“col-xs-4”></div>

<div class=“col-xs-8”></div>

</div>

</div>

MEDIA QUERIES

• min/max-width/height;

• orientation: landscape/portrait;

• device-aspect-ratio:16/9;

@media screen and (min-width:400px)

and (max-width:800px) { ... }

<meta

name=“ viewport "

content=“ width=device-width ,

initial-scale=1.0 ,

minimum-scale=1.0 ">

Worth targeting:

• 978px – desktop and large tablets

maximum page width

• 600px – tablets

Kindle Fire and other 7” tablets

• 480px – smartphones

one-column layout and mobile specific navigation

• @media only screen and (device-width: 768px) – iPad

useful for iPad specific fixes

body {min-width: 320px;

}

}

.container {overflow: hidden;}

CODING AND BROWSER SUPPORT

• Pretty web design is nothing without good HTML(5)/CSS(3)

• Web designers shouldn’t stop at “Photoshop”

• “MOBILE FIRST” methodology

We should provide high tech quality, well thought of, user

friendly and useful websites

• screen sizes

• resolutions

• way of interaction (mouse, touch, movement, voice..)

• HTML5 semantics (input type="email" / tel / url / number)

• Remove address bar

BROWSER SUPPORT

• HTML5/CSS3 - standard by 2022 (2014)

• Not all users will have the same experience

• Media queries won’t work for the currently 30% of browsers

(IE8 and below)

• Mobile browsers are up to date

• iOS Safari, Android browser, IE Mobile, Opera Mobile/Mini

• Desktop browsers are ok since IE9 on

• Chrome, Firefox, IE9, Opera, Safari
