RWD Images

We're going to use Foundation's Interchange

Interchange syntax

<img data-interchange="
    [image_path, (media query)],
    [image_path, (media query)]">

Interchange Media Queries

<img data-interchange="
    [image_path, (media query)], [image_path, (media query)]">

Name	Media Query
default	`only screen and (min-width: 1px)`
small	`only screen and (min-width: 1px)`
medium	`only screen and (min-width: 641px)`
large	`only screen and (min-width: 1024px)`
landscape	`only screen and (orientation: landscape)`
portrait	`only screen and (orientation: portrait)`
retina	`only screen and (min-device-pixel-ratio: 2), only screen and (min-resolution: 192dpi), only screen and (min-resolution: 2dppx)`

<img data-interchange="
    [image_path, (media query)], [image_path, (media query)]">

Write interchange that swaps image1.jpg with image2.jpg when it is at large

Name	Media Query
default	`only screen and (min-width: 1px)`
small	`only screen and (min-width: 1px)`
medium	`only screen and (min-width: 641px)`
large	`only screen and (min-width: 1024px)`
landscape	`only screen and (orientation: landscape)`
portrait	`only screen and (orientation: portrait)`
retina	`only screen and (min-device-pixel-ratio: 2), only screen and (min-resolution: 192dpi), only screen and (min-resolution: 2dppx)`

<img data-interchange="
    [image1.jpg, (default)], [image2.jpg, (large)]">

Now add a retina version

image1-2x.jpg

<img data-interchange="
    [image1.jpg, (default)],
    [image2.jpg, (large)],
    [image1-2x.jpg, (retina)]">

Add your own Media Query

other.jpg at screen and min-width 1px

<img data-interchange="
    [image1.jpg, (default)],
    [image2.jpg, (large)],
    [image1-2x.jpg, (retina),
    [other.jpg, (only screen and (min-width: 1px))]">

Add your own Media Query

big.jpg min-width 1280px

<img data-interchange="
    [image1.jpg, (default)],
    [image2.jpg, (large)],
    [image1-2x.jpg, (retina),
    [other.jpg, (only screen and (min-width: 1px))]
    [big.jpg, ((min-width: 1280px))]">

Interchange Notes

See the double parenthesis? Excluding only screen makes it look like that.

<img data-interchange="
    [image1.jpg, (default)],
    [image2.jpg, (large)],
    [image1-2x.jpg, (retina),
    [other.jpg, (only screen and (min-width: 1px))]
    [big.jpg, ((min-width: 1280px))]">

Interchange Notes

If breaking up the rules on new lines, each line must be a complete rule.

<img data-interchange="
    [image1.jpg, (default)],
    [image2.jpg, (large)],
    [image1-2x.jpg, (retina),
    [other.jpg, (only screen and (min-width: 1px))]
    [big.jpg, ((min-width: 1280px))]">

Name your own Media Queries

$(document).foundation('interchange', {
  named_queries : {
    myMq : '(max-width: 200px)'
  }
});

Not just for images either!

<div data-interchange="
    [../examples/interchange/default.html, (small)],
    [../examples/interchange/medium.html, (medium)],
    [../examples/interchange/large.html, (large)]">
  <div data-alert class="alert-box secondary radius">
    This is the default content.
    <a href="#" class="close">&times;</a>
  </div>
</div>

small = 12 implied when no small class is given

Foundation Grid

Encapsulated by .row

Each column needs .column or .columns

small-x (small-12 is implied if you don't specify)

medium-x (medium-12 is implied if you don't specify small)

large-x

CSS

Lots of options!

Which of the following is from the CSS3 Spec?

Media Queries ★
@font-face ★
Border-Radius ★
CSS Floats
Border-Style

Browser Compatbility

<!DOCTYPE html>
<!--[if IE 7]>         <html class="no-js lt-ie9 lt-ie8"> <![endif]-->
<!--[if IE 8]>         <html class="no-js lt-ie9"> <![endif]-->
<!--[if gt IE 8]><!--> <html class="no-js"> <!--<![endif]-->

HTML5 boilerplate

Progressive Enhancement

Modernizr

Adds classes to the html element that you can target for features

Given the following classes

borderradius, boxshadow

How should you progressively enhance .foo for browsers without these features?

.foo {
    border-radius: 10px;
    box-shadow: 3px 3px #333;
}

Attribute Selectors

elem[att^="val"] {} //– the "begins with" selector
elem[att$="val"] {} //– the "ends with" selector
elem[att*="val"] {} //– the "contains" selector

Select a tags whose hrefs start with http

^ (begin) | $ (ends) | * (contains)

a[href^="http"] {}

Select a title contains "foo"

^ (begin) | $ (ends) | * (contains)

a[title*="foo"] {}

Select a data-name ends with "heisenberg"

a[title$="heisenberg"] {}

Apply the link hover cursor to an element when hovered

Using SASS nesting

a {
    color: blue;
    &:hover {
        cursor: pointer;
    }
}

:before & :after

elem {
    &:before {
        background-color: red;
    }
    &:before {
        background-color: purple;
    }
}

::before & ::after if you are IE9+

Almost exclusively used with content

elem {
    &:before {
        content: "";
        background-color: red;
    }
}

Add three right angle brackets after a link

>>>

a {
    &:before {
        content: "&gt;&gt;&gt;";
    }
}

SVG Images

Scalable Vector Graphics

Which of the Following are true of SVG over Raster?

Smaller File Sizes
Crisp Images when Zoomed ★
SVG is highly compatible with browsers ★
Can be easily combined
Scalable ★

Embed an SVG image

image.svg

<img src="image.svg">

Data URI's

http://jpillora.com/base64-encoder/

li { 
  background: 
    url(data:image/gif;base64,R0lGODlhEAAQAMQAAORHHOVSKudfOulrSOp3WOyDZu6QdvCchPGolfO0o/XBs/fNwfjZ0frl3/zy7////wAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAACH5BAkAABAALAAAAAAQABAAAAVVICSOZGlCQAosJ6mu7fiyZeKqNKToQGDsM8hBADgUXoGAiqhSvp5QAnQKGIgUhwFUYLCVDFCrKUE1lBavAViFIDlTImbKC5Gm2hB0SlBCBMQiB0UjIQA7)
    no-repeat
    left center;
  padding: 5px 0 5px 25px;
}

Be careful with data URI's

Can get HUGE, FAST!

Tend to be very slow on mobile devices

Gradients

Official CSS Spec:

background: linear-gradient(top, #333333, #00cc0)

Browser Compatibility

Vendor Prefixes FTL

background: -webkit-gradient(linear, left top, left bottom, from(#333333), to(#00cc00));
background: -webkit-linear-gradient(top, #333333, #00cc00);
background: linear-gradient(top, #333333, #00cc00);

Vendor prefixes are going away

Luckily you don't have to worry about them much anymore, they have been abstracted away from typical developement in the recent years.

Vendor Prefixes

Compass / Auto Prefixer do this for you now.

We're going to focus on Compass today

Which of the following will compile with Compass to proper CSS?

background: linear-gradient(top, #333, #000);

background: @include linear-gradient(top left, #333, #0c0);

@include background(linear-gradient(top left, #333, #0c0)); ★

@include background(image-url("foo.png"),
         linear-gradient(top left, #333, #0c0)); ★

background: url(foo.png),
            linear-gradient(top, #333333, #00cc00);

Compass is just a collection of Mixins

So pull them in using @include's

Browse to compass-style.org

Click Reference

"examples" are your friends.

We'll be using Sassmeister

http://sassmeister.com

Click HTML (may need to refresh page after enabling)

Start by Importing Compass

Your first two lines of a sass file should be:

@charset "UTF-8";
@import "compass";

Div with background image foo.png

background-image: url(foo.png);

Div with background image foo.png &
Linear gradient top left #000 to #fff

Compass images

@include background(image-url("foo.png"),
         linear-gradient(top left, #000, #fff));

text-shadow 3px, box-shadow 5px

@include text-shadow(3px);
@include box-shadow(5px);

Define all link colors in one line

@include link-colors($normal, $hover, $active, $visited, $focus);

Div with box-sizing border-box

@include box-sizing(border-box);

Custom font (2 font types, ttf, woff)

@include font-face("Name", font-files("name.ttf", "name.woff"));

Buuuuuut....

Compass fonts aren't bulletproof

For "Bullet-Proof" we use Nicole Sullivan's technique

Icon Fonts

You can also use Zurb's Icon fonts

Foundation Icon Fonts 3

Fontello is a viable alternative, it also lets you pick and choose fonts and add your own images as fonts

Foundation Icons

Create a button with a Star icon to the left of it

<button><i class="fi-star"></i> Star</button>

Sass & Color

Interactive demo Sass color functions

Make a div have 50% opacity

@include opacity(50);

Only need this for providing Old IE opacity, if not just use "opacity: .5;"

RGBa Color

Opacity affects HEX colors and whatever they contain

rgba(255, 255, 255, 0.5);

Give a div #bada55 background color with 70% opacity

background: rgba(186, 218, 85, 0.7);???

background: rgba(#bada55, 0.7);
