What is responsive design?

What is responsive design?More than just a buzzword

The web design approach for building sites that adapt and are optimized for a range of screen resolutions, sizes, and formats.

They “respond” to the conditionsin which the site is viewed.

Common breakpointsFor most screen sizes

• 320 px – Mobile portrait• 480 px – Mobile landscape• 600 px – Small tablet• 768 px – Tablet portrait• 1024 px – Tablet landscape/Netbook• 1280 px & greater – Desktop

Mobile web design best practices

Best practices & considerationsThink about how people use their phones

• Consider hand placement• Avoid edges and corners if possible• Place content in the middle and give room to scroll• Make targets an appropriate, easy-to-tap size• Don’t place anything important under a target/button

Good luck.

How to implement it on the web(yes, that means writing code)

CSS Media Queries

.content { width: 1024px; margin: 0 auto; background: red;}

Start with some basic CSS.

What a lovely red box!

That doesn’t seem quite right...

.content { width: 1024px; margin: 0 auto; background: red;}

@media screen and (max-width: 1023px) { .content { width: 100%; margin: 0 20px; }}

Let’s add in some media queries.

Much better!

So... break that down.

@media screen and (max-width: 1023px) { ... }

rule media parameters

@media screen and (max-width: 1023px) { ... }

print

handheld

projection

tv

aural

braille

embossed

tty

all

@media screen and (max-width: 1023px) { ... }

min-width

max-device-width

min-device-width

min-resolution

color

.content { width: 50%; margin: 0 auto; background: red;}

@media screen and (min-width: 320px) and (max-width: 480px) { .content { width: 100%; }}

Between a range of screen sizes.

.content { width: 50%; margin: 0 auto; background: red;}

@media screen and (min-width: 320px) and (max-width: 480px) { .content { width: 100%; }}

Between a range of screen sizes.

.content { width: 100%; margin: 0 auto; background: red;}

@media screen and (orientation: portrait) { .content { width: 50%; }}

Orientation of the device or window.

.content { width: 100%; margin: 0 auto; background: red;}

@media screen and (orientation: portrait) { .content { width: 50%; }}

Orientation of the device or window.

.my-image { width: 100px; background: url(my-image.jpg);}

@media (-webkit-min-device-pixel-ratio: 2), (min-resolution: 192dpi) { .my-image { background-image: url(my-image@2x.jpg); background-size: 100%; } }

On retina or high-resolution displays.
