<p>HTML5 introduces several <em>really</em>
useful elements and a ton of new APIs.</p>

<p>Please fill out the form below.
<strong>Note: all fields are required.</strong></p>

<p>I like to work with markup languages because
<strong>they are simple and easy to read</strong>.
They also have that certain <i lang="fr" title="I

Media Queries


@Media blocks
@media screen {
/* Styles for screen media only */
}


@Media blocks+
@media screen and (max-width:450px) {
/* Styles for screen media when browser
is 450px wide or below */
}


Getting granular
@media
screen and (min-device-width:1024px)
and (max-width:989px),
screen and (max-device-width:480px),
screen and (max-device-width:480px)
and (orientation:landscape),
screen and (min-device-width:481px)
and (orientation:portrait) {
/* Layout for narrower desktop (below 990px)
or
iPhone running iOS 3 (or equivalent)
or

or

}


Mobile First w/ media queries
/* Universal Layout */

@media screen {
/* Styles for all screens */
}

@media screen and (min-width:481px) {
/* Styles for all screens 480px+ width */
}

@media screen and (min-width:754px) {
/* Styles for all screens 754px+ width */

Sins of our past
<a href="javascript:someFunction();">some text</a>

<a href="javascript:void(null);"
onclick="someFunction();">some text</a>

<a href="#" onclick="someFunction();">some text</a>


A minor improvement
<a href="http://offsite.com"
onclick="newWin( this.href ); return false;">
some text</a>


Event listeners
window.onload = handleExternalLinks;

function handleExternalLinks()
{
var server = document.location.hostname;
var anchors = document.getElementsByTagName("a");
var i, href;
for( i=0; i < anchors.length; i++ )
{
href = anchors[i].href;
if ( href.indexOf("http://" + server) == -1 &&
href.indexOf("https://" + server) == -1 )
{
// HREF is not a file on my server
anchors[i].onclick = function()
{
newWin( this.href );
};
}
}
}


Listen and delegate
document
.getElementsByTagName( 'body' )[0]
.onclick = clickDelegator;

function clickDelegator( e )
{
e = ( e ) ? e : event;
var el = e.target || e.srcElement;
// external links
if ( el.nodeName.toLowerCase() == 'a' &&
el.getAttribute( 'rel' ) == 'external' )
{
newWin( el.href );
}
}


Test for dependencies
function someFunction()
{
if ( !document.getElementsByTagName ) return;

// code that uses document.getElementsByTagName()

}


{
if ( !document.getElementsByTagName ||
!document.getElementById ) return;

/* code that uses document.getElementsByTagName()
and document.getElementById() */

}


{
if ( !document.getElementsByTagName ||
!document.getElementsByTagName('p') ) return;

// code that requires the presence of a P element

}


{
if ( !document.getElementById ||
!document.getElementById('content') ) return;

// code that requires the presence of #content

}


{
if ( typeof( Prototype ) == 'undefined' ||
parseFloat( Prototype.Version ) < 1.5 ) return;

// code that uses Prototype 1.5 or higher

}


window.addEventListener(
'load',
function(){
if ( document.getElementsByTagName &&
document.getElementById )
{
someFunction();
}
},
false
);


Anchor-include pattern
Source of blog entry page

<a href="/archives/{entry_date format='%Y/%m/%d'}/{url_title}/
comments/#comments"
data-replace="/comments/{url_title}/">View comments on this
entry and add your own</a>

{if segment_4=="comments"}
<section id="comments" class="focal">
{embed="inc/.comments" url_title="{url_title}"}
</section>
{if:else}
{comment_loader}
{/if}
Examples use ExpressionEngine tags


Source of /comments/{url_title} (technically /pages/comments/{url_title})

{embed="inc/.comments" url_title="{segment_3}"}
Example uses ExpressionEngine tags


https://gist.github.com/b976b67e88ffbfc9f125

$.fn.ajaxInclude = function(){
return this.each(function() {
var $el = $( this ),
target = $el.data( 'target' ),
$targetEl = target && $( target ) || $el,
methods = [ 'append', 'replace', 'before', 'after' ],
ml = methods.length,
method,
url;
while ( ml-- ) {
method = methods[ ml ];
if ( $el.is( '[data-' + method + ']' ) ) {
url = $el.data( method );
break;
}
}
if ( method == 'replace' ) { method += 'With'; }
if ( url && method ) {
$.get( url, function( data ){
$el.trigger( 'ajaxInclude', [$targetEl, data] );
$targetEl[ method ]( data );
});
}
});
};


Replace:
<a data-replace="articles/latest/fragment"
href="...">Latest Articles</a>

Before:
<a data-before="articles/latest/fragment"

After:
<a data-after="articles/latest/fragment"


$("[data-append],[data-replace],”+
“[data-after],[data-before]").ajaxInclude();

Remember stu like this?
<a href="foo.html"
style="color:blue;"
onmouseover="this.style.color='red'"
onmouseout="this.style.color='blue'">Foo</a>


Remember stu like this?
<a href="foo.html"
style="color:blue;"
onmouseover="this.style.color='red'"
onmouseout="this.style.color='blue'">Foo</a>

a, a:link, a:visited {
color: blue;
}
a:hover {
color: red;
}


Isn’t this the same?
for( i=0; i<objects.length; i++){
objects[i].style.display = 'none';
}


Small improvement
objects[i].style.position = 'absolute';
objects[i].style.left = '-999em';
}


Separation
objects[i].addClassName( 'hidden' );
}

.hidden {
position: absolute;
left: -999em;
}

Option 1: Add by hand
/* =START WickedCool Script CSS (do not remove) */
.wicked {
color: red;
font: bold 4em/2 "Comic Sans";
}
.cool {
color: blue;
font: bold 4em/2 "Comic Sans";

Option 2: Include by hand
<script src="WickedCool.js"></script>
<link rel="stylesheet" href="WickedCool.css" />

Option 2: Include by hand

<head>

</head>
<body>

</body>


Option 3: Scripted include
function FindPath( filename )
{
var path = false;
var scripts = document.getElementsByTagName( 'script' );
for( var i=0; i<scripts.length; i++ )
{
if( scripts[i].getAttribute( 'src' ) &&

.replace( new RegExp( filename ), '' );
break;
}
}
return path;
}


Option 3: Scripted include
var WickedCool = {
jsFile: 'WickedCool.js',
cssFile: 'WickedCool.css',
initialize: function(){
// determine the path
var path = FindPath( this.jsFile );
// add the CSS file
var css = document.createElement( 'link' );

css.setAttribute( 'href', path + this.cssFile );
document.getElementsByTagName( 'head' )[0]
.appendChild( css );
// do the rest of the wicked cool stuff
}
};


Option 4: Scripted embed
function addCSS( styles )
{
var el = document.createElement( 'style' );
el.setAttribute( 'type', 'text/css' );
if ( el.styleSheet )
{
el.styleSheet.cssText = styles;
}
else
{
el.appendChild( document.createTextNode( styles ) );
}

.appendChild( el );
}


Option 4: Scripted embed
var WickedCool = {
_css: '.wicked { color: red; ' +
' font: bold 4em/2 "Comic Sans"; } ' +
'.cool { color: blue; ' +
' font: bold 4em/2' "Comic Sans"; }',
initialize: function()
{
// add the CSS
addCSS( this._css );
// do the rest of the wicked cool stuff
}
};

Apply No Style
Before Its Time


How do we do that?
.TabInterface-folder {
/* ... */
}

#TabInterface .tab {
/* ... */
}
#TabInterface .tab.active {
/* ... */
}

190


How do we do that?
Tactic Default Activated

add “-on” to the class .tabbed .tabbed-on

add an activation class .auto-submit .auto-submit.active

change the form of the
.replace-me .replaced
class

Typical hiding schemes
Accessibility
CSS Rules Display E ect
E ect
visibility: hidden; Element is hidden from Content is ignored by screen
view, but is not removed readers
from the normal ow (i.e. it
still takes up the space it
normally would)

display: none; Element is removed from Content is ignored by screen
the normal ow and hidden; readers
the space it occupied is
collapsed

height: 0; Element is collapsed and Content is ignored by screen
width: 0; contents are hidden readers
overflow: hidden;


Accessibility
E ect
text-indent: -999em; Contents are shifted o - Screen readers have access
screen and hidden from to the content, but the
view, but links may “focus” content is limited to text and
oddly and negative indent inline elements
may not prove long enough
to fully hide content

position: absolute; Content is removed from Screen readers have access
left: -999em; the normal ow and shifted to the content
o the left-hand edge; the
space it occupied is
collapsed


Accessibility
E ect
position: absolute; Content is positioned Screen readers have access
/* IE6, IE7 */ absolutely (and is removed to the content
clip: rect(
1px 1px 1px 1px from the normal ow), but
); remains in place and is
/* W3C */ clipped to become invisible
clip: rect(
1px, 1px, 1px, 1px
);
padding: 0;
border: 0;
height: 1px;
width: 1px;
overflow: hidden;

Managing focus
<div tabindex="0">
<p>This <code>div</code> can now receive focus using a
keyboard’s <kbd>tab</kbd> key. How cool is that?</p>
</div>

<div tabindex="-1">
<p>This <code>div</code> won’t be focused by a user via the
<kbd>tab</kbd> key, but JavaScript can <code>focus()</code> it.
Nifty, huh?</p>
</div>
