<h1>Slide Shows in HTML and XHTML</h1>

<ul>
<li>You can now create accessible slide shows with ease</li>

<li>Works across browsers and is operated like PowerPoint

<ul>
<li>Advance to next slide with mouse click, space bar or swipe left</li>

<li>Move forward/backward between slides with Cursor Left,
Cursor Right, <strong>Pg Up</strong> and <strong>Pg Dn</strong>
keys, or swipe left or right</li>

<li><strong>Home</strong> key for first slide, <strong>End</strong>
 key for last slide</li>

<li>Function <strong>F11</strong> to go full screen and back</li>

<li>The "<strong>F</strong>" key toggles the display of the footer</li>

<li>The "<strong>A</strong>" key toggles display of current vs all
slides

<ul>
<li>Try it now to see how to include notes for handouts (this is
explained in the notes following this slide)</li>
</ul>
</li>

<li>Font sizes automatically adapt to browser window size

<ul>
<li>use <strong>S</strong> and <strong>B</strong> keys for
manual control (or &lt; and &gt;, or the <strong>-</strong> and

<div class="handout">
<p>For handouts, its often useful to include extra notes using a
div element with class="handout" following each slide, as in:</p>

<pre>
&lt;div class="slide"&gt; 
 <em>... your slide content ...</em>
&lt;/div&gt;

&lt;div class="handout"&gt;
 <em>... stuff that only appears in the handouts ...</em>

<h1>What you need to do</h1>

<ul>
<li>Each presentation is a single XHTML file</li>

<li>Each slide is enclosed in <em>&lt;div class="slide"&gt; ...
&lt;/div&gt;</em>

<ul>
<li>The div element will be created automatically for h1
elements that are direct children of the body element.</li>
</ul>

</li>

<li>Use regular markup within each slide</li>

<li>The document head includes two links:
<ul>
<li>The slide show style sheet:
<a href=
"http://www.w3.org/Talks/Tools/Slidy2/styles/slidy.css">http://www.w3.org/Talks/Tools/Slidy2/styles/slidy.css</a></li>

<li>The slide show script: <a href=
"http://www.w3.org/Talks/Tools/Slidy2/scripts/slidy.js">http://www.w3.org/Talks/Tools/Slidy2/scripts/slidy.js</a></li>

<li>Or you can link to the compressed version of the script which is about
one seventh the size, see <a href=
"http://www.w3.org/Talks/Tools/Slidy2/scripts/slidy.js.gz">http://www.w3.org/Talks/Tools/Slidy2/scripts/slidy.js.gz</a></li>
<li>If you are using XHTML, remember to use &lt;/script&gt; and
&lt;/style&gt; as per <a
href="http://www.w3.org/TR/xhtml1/#C_3">Appendix C.3</a></li>

<h1>To get the W3C Blue Style</h1>

<p>The head element should include the following link to the style
sheet:</p>

<pre>
&lt;link rel="stylesheet" type="text/css" media="screen, projection, print"
 href="http://www.w3.org/Talks/Tools/Slidy2/styles/w3c-blue.css" /&gt; 
</pre>

<p>The body element's content should start with the following
markup:</p>

<pre>
&lt;div class="background"&gt; 
  &lt;img id="head-icon" alt="graphic with four colored squares"
    src="http://www.w3.org/Talks/Tools/Slidy2/graphics/icon-blue.png" /&gt; 
  &lt;object id="head-logo" title="W3C logo" type="image/svg+xml"
    data="http://www.w3.org/Talks/Tools/Slidy2/graphics/w3c-logo-white.svg"&gt;&lt;img
   src="http://www.w3.org/Talks/Tools/Slidy2/graphics/w3c-logo-white.gif" 
   alt="W3C logo" id="head-logo-fallback" /&gt;&lt;/object&gt;
&lt;/div&gt; 
</pre>

<p>This adds the logos on the top left and right corners of the
slide.</p>

<p>You are of course welcome to create your own slide designs.
You can provide different styles and backgrounds for
different slides (more details later).</p>

<p>Use the <em>meta element</em> with <em>name="copyright"</em>
for use in the slide show footer:</p>

<pre>
&lt;meta name="copyright" 
content="Copyright &amp;#169; 2005-2009 W3C (MIT, ERCIM, Keio)" /&gt; 
</pre>
</div>

<div class="slide">
<h1>Upgrading from previous versions of Slidy</h1>

<ul>
<li>This uses a new version of the HTML Slidy script</li>
<li>It is designed to work better with other scripts,
e.g. for UI controls within your slides
<ul>
<li>Only adds one global name "w3c_slidy"</li>
<li>Doesn't interfere with other scripts that set event handers
such as onload on body element</li>
</ul>
</li>
<li>Works for slides delivered as text/html  and application/xhtml+xml</li>
<li>New presentation timer feature</li>
<li>Initial prompt on first slide to help newcomers to Slidy</li>
<li>Better support for styling slides and printing them</li>
<li>Requires additional style rules, so new script won't work
with old presentations without changes to their style sheets
<ul>
<li>See <a href="styles/slidy.css">slidy.css</a>, and
<a href="styles/w3c-blue.css">w3c-blue.css</a></li>
</ul>
</li>
<li>But old presentations will work unchanged as they refer to
the old script!</li>
</ul>
</div>

<div class="slide">
<h1>To use it off-line</h1>

<ul>
<li>You can download <a href="slidy.zip">slidy.zip</a> and unzip
it to create a Slidy directory on your machine</li>

<li>If you have cvs access to the W3C site you can check out the Slidy
directory</li>

<li>Remember to periodically check for updates</li>

<li>You then have two choices:

<ol>
<li>Use relative URIs depending on your local setup to access the
appropriate files. Use the same directory structure as on the W3C
server, ie, ".../2005/Talks/...".</li>

<li>Run a Web server on your machine so that the directory above
can be accessed via <code>http://localhost/Talks/Tools/Slidy2</code>
and use the URIs of the form "/Talks/Tools/Slidy2/styles/slidy.css",
"/Talks/Tools/Slidy2/scripts/slidy.js".</li>
</ol></li>

<li>In both cases you can then publish your files on the W3C server
unchanged.</li>

<li><strong>NOTE</strong> Internet Explorer on Windows XP now disables
scripting for web pages loaded directly from the local file system,
a work around is to use another browser, e.g. Firefox or Opera</li>

<li>Please feel free to create your own designs, and help us to build
a gallery of Slidy styles.</li>

<li>My <a href="/2006/02/woa/">Google TechTalk</a> (1st Feb 2006)
uses a notebook themed style</li>
</ul>
</div>

<div class="slide">
<h1>Timing Your Presentation</h1>

<ul>
<li>Sometimes it is handy to know just how much time you have to
left to finish your presentation</li>
<li>To get this feature, add the following markup to the
content of the head element, replacing 5 by the duration
of your presentation in minutes
<pre>&lt;meta name="duration" content="5" /&gt;</pre>
</li>
<li>The time left in minutes and seconds is shown in the footer
next to the slide number</li>
<li>The clock starts to run when you move away from the first slide</li>
<li>Moving back to the first slide pauses the clock</li>
</ul>


</div>

<div class="slide slanty">
<h1>Generate a Title Page</h1>

<p>If you want a separate title page with the W3C blue style, the
first slide should be as follows:</p>

<pre>
&lt;div class="slide cover"&gt; 
 &lt;img src="http://www.w3.org/Talks/Tools/Slidy2/graphics/keys.jpg" 
  alt="Cover page images (keys)" class="cover" /&gt; 
 &lt;br clear="all" /&gt;            
 &lt;h1&gt;HTML Slidy: Slide Shows in XHTML&lt;/h1&gt; 
 &lt;p&gt;&lt;a href="http://www.w3.org/People/Raggett/"&gt;Dave Raggett,&lt;/a&gt; 
 &lt;a href="mailto:dsr@w3.org"&gt;dsr@w3.org&lt;/a&gt;&lt;/p&gt; 
&lt;/div&gt; 
</pre>

<p>The <a 
href="http://www.w3.org/Talks/Tools/Slidy2/graphics/w3c-blue.css">w3c-blue.css</a> 
style sheet looks for the classes "slide" and "cover" on div
and img elements using the CSS selector <em>div.slide.cover</em></p>

<p>This technique can be used to assign your slides to different
classes with a different appearence for each such class.</p>

<p>Slidy also allows you to use different background markup for
different slides, based upon shared class names, as in "foo" below.
Backgrounds without additional class names are always shown except
when the slide isn't transparent. You may need to tweak your
custom style sheet.</p>

<pre>
&lt;div class="background foo"&gt;
   ... background content ...
&lt;div&gt;

...

&lt;div class="slide foo"&gt;
   ... slide content ...
&lt;div&gt;
</pre>
</div>

<div class="slide">
<h1>Incremental display of slide contents</h1>

<p>For incremental display, use class="incremental", for
instance:</p>

<ul class="incremental">
<li>First bullet point</li>

<li>Second bullet point</li>

<li>Third bullet point</li>
</ul>

<p class="incremental">which is marked up as follows:</p>

<pre class="incremental">
&lt;ul class="incremental"&gt; 
  &lt;li&gt;First bullet point&lt;/li&gt; 
  &lt;li&gt;Second bullet point&lt;/li&gt; 
  &lt;li&gt;Third bullet point&lt;/li&gt; 
&lt;/ul&gt; 
 
&lt;p class="incremental"&gt;which is marked up as follows:&lt;/p&gt; 
 
&lt;pre class="incremental"&gt; 
 ... 
&lt;/pre&gt; 
</pre>

<div class="footnote">
<p>An element is incrementally revealed if its parent element has
class="incremental" or if itself has that attribute. Text nodes are
not elements and are revealed when their parent element is revealed.
You can use class="incremental" on any element except for &lt;br /&gt;.
Use class="non-incremental" to override the effect of setting the
parent element's class to incremental.</p>

<p>Note: you will see a red asterisk on the left of the toolbar
when there is still something more to reveal.</p>
</div>
</div>

<div class="slide">
<h1>Create outline lists with hidden content</h1>

<p>You can make your bullet points or numbered list items
into outlines that you can expand or collapse</p>

<ul class="outline">
<li>Just add <em>class="outline"</em> to the ul or ol
element. Click on this list item for more details.

<ul>
<li>The Slidy script will then treat the list
as an outline list.</li>
<li>Clicking on outline list items will expand/collapse
block-level elements within that list item.</li>
<li>Click on the above to make this list item
collapse again.</li>
</ul>
</li>
<li>Users will then see expand/collapse icons as appropriate
and may click anywhere on the list item to change its state.
This particular list item can't be expanded or collapsed.</li>
<li class="expand">Add class="expand" to any li elements that
you want to start in an expanded state.

<ul>
<li>By default Slidy hides all the block level elements within the
outline list items unless you have specified class="expand".</li>
<li>Such pre-expanded items can be collapsed by clicking on them.</li>
</ul>
</li>
<li>Note expand/collapse icon highlighting requires browser
support for :hover which isn't supported by IE6.

<ul>
<li>Microsoft says it will be supported by IE7 along with 
many fixes for other CSS woes in IE6.</li>
</ul>
</li>
</ul>

<pre>
&lt;ol class='outline'&gt;
  &lt;!-- topic 1 starts collapsed --&gt;
  &lt;li&gt;Topic 1
    &lt;ol&gt;
        &lt;li&gt;subtopic a&lt;/li&gt;
        &lt;li&gt;subtopic b&lt;/li&gt;
    &lt;/ol&gt;
  &lt;/li&gt;

<h1>Incremental display of layered images</h1>

<p>These can be marked up using CSS relative positioning, e.g.</p>

<pre>
&lt;div class="incremental" 
 style="margin-left: 4em; position: relative"&gt; 
  &lt;img src="graphics/face1.gif" alt="face" 
   style="position: static; vertical-align: bottom"/&gt; 
  &lt;img src="graphics/face2.gif" alt="eyes" 
    style="position: absolute; left: 0; top: 0" /&gt; 
  &lt;img src="graphics/face3.gif" alt="nose" 
    style="position: absolute; left: 0; top: 0" /&gt; 
  &lt;img src="graphics/face4.gif" alt="mouth" 
    style="position: absolute; left: 0; top: 0" /&gt; 
&lt;/div&gt; 
</pre>

<p style="font-size: smaller;">You should also use transparent GIF
images to avoid the IE/Win bug for alpha channel in PNG. A fix is
expected in IE 7. A <a href=

available on skyzyx.com. My thanks to <a href=

<pre>
&lt;div class="vbox"&gt;&lt;/div&gt;
&lt;div class="hbox"&gt;
Place the content here
&lt;/div&gt;
</pre>
<p>and style it with the following:</p>
<pre>
div.vbox {
  float: left;
  height: 40%; width: 50%;
  margin-top: -220px;
}
div.hbox {
  width:60%;  margin-top: 0;
  margin-left:auto; margin-right:auto;
  height: 60%;

  clear:both;
}
</pre>

<p>The above styling is included in <a href="styles/w3c-blue.css">w3c-blue.css</a>,
which is designed to be used with <a href="styles/slidy.css">slidy.css</a>, but you
are encouraged to develop your own style sheet with your own look and feel.</p>
</div>
</div>

<div class="slide">
<h1>Include SVG Content</h1>

<p>Inclusion of SVG content can be done using the object element,
for example:</p>

<div style="text-align: center;"><object data="graphics/example.svg" type=
"image/svg+xml" title="Indian Office logo" height="10%" width=
"50%"><img src="graphics/example.png" alt="Indian Office logo" width=
"50%" /></object></div>

<p>has been achieved by:</p>

<pre>
&lt;object data="graphics/example.svg" type="image/svg+xml" 
  width="50%" height="10%" title="Indian Office logo"&gt; 
    &lt;img src="graphics/example.png" width="50%" 
          alt="Indian Office logo" /&gt; 
&lt;/object&gt; 
</pre>

<p>This ensures that the enclosed png is displayed when the browser
has no plugin installed or can't display SVG directly. Providing
such a fall back is very important! Don't forget the alt text for
people who can't see the image.</p>

<p>However, there are caveats, see the next slide!</p>
</div>

<div class="slide">
<h1>Caveats with SVG+object</h1>

<p>Adobe has recently withdrawn support for its SVG Viewer, so you are
recommended to consider <a
href="http://wiki.svg.org/Viewer_Implementations">alternatives</a>.
If you still using the Adobe SVG viewer you should be aware of bugs
when using the it with IE, Namely:</p>

<ul>
<li>Most modern browsers generally support SVG SVG Tiny 1.1 or better
natively without the need for a plugin</li>

<li>If you need to use Internet Explorer you are advised to upgrade
to IE9 which includes native support for SVG.</li>

<li>Patches to Internet Explorer mean that the Adobe SVG Viewer
version 3.03 no longer works with IE6. You are therefore recommended
to uninstall version 3.03 and instead install <a
href="http://www.adobe.com/svg/viewer/install/beta.html">Adobe SVG Viewer
6.0 preview</a> if this is available to to you.</li>

<li>IE6 makes a <em>copy</em> of the SVG file on the local disc
when displaying it; but doesn't pass the original URI to the plugin</li>

<li>As a result relative references from within the SVG to external
resources (scripts, CSS, images, other SVG) will break.</li>

<li>The work around is to use absolute references within your SVG.</li>

<li>On Windows, the Adobe SVG plugin doesn't respect the CSS z-index
property, and if used on backgrounds will always show through other
content</li>
</ul>
</div>

<div class="slide">
<h1>Additional Remarks</h1>

<ul>
<li>Slides are auto-numbered on the slide show footer</li>

<li>You can link into the <a href="#(2)">middle</a> of a slide
show:

<ul>
<li>It works out which slide you want and hides the rest</li>

<li>You can even link between slides in the same slide show</li>

<li>Individual sides can be addressed with the syntax #(<em>slide
number</em>),<br />
e.g. slide 3 of this presentation is: <a href=
"#(3)">http://www.w3.org/Talks/Tools/Slidy#(3)</a>
<ul>
<li>Previous versions of Slidy used square brackets, which will
also work.</li>
</ul></li>
<li>Note that the browser's back/forward buttons may not work as
you might expect due to browser problems.</li>
</ul>
</li>

<li>Adding "title" to the list of classes for div elements that serve
as title pages will render the corresponding entry in the table of
contents in bold italic text (press "C" now for an example)</li>

<li>If your slides have more content than normal, use a <em>meta
element</em> to request a smaller font

<ul>
<li>the following requests fonts to be one step smaller than
the Slidy default for the current window width, and positive
integers will make the fonts correspondingly larger</li>
</ul>

<pre>
&lt;meta name="font-size-adjustment" content="-1" /&gt; 
</pre>

<ul>
<li>Slidy uses JavaScript to dynamically set the font size on the
body element, but it is okay to specify relative font changes on
other elements within your own style sheet, e.g.</li>
</ul>
<pre>div.slide.large { font-size: 200% }</pre>
</li>

<li>You are encouraged to ensure your markup is valid. <a href=
"http://www.w3.org/People/Raggett/tidy/">HTML Tidy</a> can be used
to find and correct common markup problems</li>

<li>The slide show script and style sheet can be used freely under
W3C's <a href=
"http://www.w3.org/Consortium/Legal/copyright-software">software
licensing</a> and <a href=
"http://www.w3.org/Consortium/Legal/copyright-documents">document

<h1>Localization and automatic translation</h1>

<p>Slidy now includes support for localization</p>

    "es":this.strings_es,
    "ca":this.strings_ca,
    "cs":this.strings_cs,
    "nl":this.strings_nl,

    "jp":this.strings_ja,
    "zh":this.strings_zh,
    "ru":this.strings_ru,
    "sv":this.strings_sv

<ul>
<li>The tool bar is localized according to the language of the presentation</li>
<li>This is taken from the xml:lang or lang attributes on the html element</li>
<li>The <a href="http://www.w3.org/Talks/Tools/Slidy2/help/help.html">help file</a> is
selected based upon your browser's language preferences</li>
<li>As of 29th July 2010, the languages supported are: English,
Spanish, Catalonian, Czech, Dutch, German, Polish, French,
Hungarian, Italian, Greek, Japanese, Chinese, Russian and
Swedish</li>
<li>If you would like to contribute localizations for other languages,
please get in touch with Dave Raggett &lt;dsr@w3.org&gt;</li>
<li>The following illustrates what was used for Spanish</li>
</ul>
<pre>
// for each language there is an associative array

<h1>Future Plans</h1>

<p>Recent additions have included a table of contents, and a way to
hide and reveal content in the spirit of outline lists. The
script has been rewritten to make it easier to combine with other
scripts, e.g. for UI controls, and support swipes for navigation on
touch screen devices. Further work is anticipated on the
following:</p>

<ul>
<li>Collecting a gallery of good looking slide themes
<ul>
<li>Opportunities for graphics designers!</li>
</ul>
</li>
<li>Bob Ferris has worked on <a
href="https://github.com/zazi/slidy_tud/blob/master/README.md">a
number of UI extensions</a> which could be incorporated into the
W3C slidy script.</li>
<li>Getting SVG Tiny to work on IE without need for SVG plugin
<ul>
<li>Using scripts to dynamically convert SVG Tiny to VML</li>
<li>Note that IE9 introduces native SVG support, so it may
no longer be worth working on SVG to VML for rendering of SVG</li>
</ul>
</li>
<li>Pre-alpha version of wysiwyg slide editor (see <a
href="editor/editor-screenshot1.png">screenshot</a>)
<ul>
<li>Using contentEditable when available, otherwise
falling back to textarea and plain text conventions</li>
<li>Using XMLHttpRequest to dynamically reflect changes to server</li>
</ul>
</li>
<li>Mechanism for remotely driving Slidy as part of distributed meetings
<ul>
<li>Using XMLHttpRequest to listen for navigation commands</li>
<li>Using VoIP for accompanying audio and teleconferencing</li>
<li>Synchronizing recorded spoken presentation with currently viewed slide</li>
</ul>
</li>
<li>Filters from PowerPoint and Open Office
<ul>
<li>and export to PDF via <a href="http://www.princexml.com/">PrinceXML</a></li>
</ul>
</li>
</ul>

class values "slide" and "handout" for div elements. Slidy doesn't
support the "layout" class featured in S5 and Opera Show, but
instead provides a more flexible alternative with the "background"
class, which enables different backgrounds on different slides.</p>
