<h3>ToC Layout and styling</h3>
<div class="gradient text">
<h4>Table of Contents styling</h4>
<p>When a Table of Contents is generated by mPDF using e.g. <tocpagebreak>, mPDF 5.7 will generate the ToC as HTML. This means that a CSS stylesheet can be used to format its appearance.</p>
</div>
<div class="gradient text">
<p>Example table of contents:</p>
<div class="mpdf_toc" id="mpdf_toc_0">
<div class="mpdf_toc_level_0">

<dottab outdent="2em" />

<div class="gradient text">
<p>Example Styling using CSS</p>
<p>The following CSSwill format the ToC as it appears in this document:</p>
<p class="code">

span.mpdf_toc_p_level_2 { }<br /><br />
</p>
<p>NB padding-right should match <dottab> "outdent" (0 is default). See <dottab> for more details</p>
</div>
<div class="gradient text">
<p>The functions TOCpagebreakByArray() and TOCpagebreak() have a new final parameter, and HTML tags <TOC> and <TOCpagebreak> have a new attribute "tocoutdent". This should be blank or a valid CSS length e.g. "2em". See <dottab> for more details.</p>

<div class="gradient text">
<p>A Table of Contents and/or Bookmarks can be generated automatically from any of the heading tags H1 - H6. This example will generate ToC and bookmarks from all <h3> tags (top level) and <h4> tags (next level)</p>
<p class="code">
$mpdf->h2toc = array(\'H3\'=>0, \'H4\'=>1);<br />
$mpdf->h2bookmarks = array(\'H3\'=>0, \'H4\'=>1);
</p>
</div>
<h3>Improved line-breaking</h3>
<p>mPDF will now avoid line-breaks in the middle of words even between <tags></p>
<div class="gradient text">
<p class="code">
<b>Na<sub>2</sub>HCO<sub>3</sub></b>
</p>
<p>Pellentesque purus feugiat semper. Donec nunc odio, et vitae pellentesque. Pellentesque <b>Na<sub>2</sub>HCO<sub>3</sub></b> velit lacus.</p>
</div>
<h3>CSS hyphens</h3>
<div class="gradient text">
<p>The CSS property hyphens is now supported on all block elements</p>
<p class="code">
hyphens: manual | auto | none
</p>
<p>In the following example, the word interdependent contains no soft hyphen or similar characters, and is moved to the next line.</p>
<p style="hyphens:none;border: 1px solid #000000;">Cum velit lacus pena sociis natoque penatibus et magnis disa montes, nascetur ridicuus interdependent (no characters suggesting line-break).</p>
<p><b>manual</b> (default)
Words are only broken at line breaks where there are characters inside the word that suggest line break opportunities. Characters can be explicit ("-" hard hyphen) or conditional (&shy; &#173; <wbr>). </p>
<p style="hyphens:manual;border: 1px solid #000000;">Cum velit lacus pena sociis natoque penatibus et magnis disa montes, nascetur ridicuus inter­dependent (uses soft hyphen &shy;).</p>
<p><b>none</b> - Words are not broken at line breaks, even if characters inside the word suggest line break points. </p>
<p style="hyphens:none;border: 1px solid #000000;">Cum velit lacus pena sociis natoque penatibus et magnis disa montes, nascetur ridicuus inter-dependent (hard hyphen).</p>
<p><b>auto</b>
Words can be broken at appropriate hyphenation points, as determined by characters inside the word.</p>
<p style="hyphens:auto;border: 1px solid #000000;">Cum velit lacus pena sociis natoque penatibus et magnis disa montes, nascetur ridicuus interdependent (No characters suggesting line-break).</p>
<p>SHY inside the word take priority over hyphenation points determined by other resources. </p>
<p style="hyphens:auto;border: 1px solid #000000;">Cum velit lacus pena sociis natoque penatibus et magnis disa montes, nascetur ridicuus inter­dependent (uses soft hyphen &shy;).</p>
<p>The configurable variables $this->hyphenate and $this->hyphenateTables are henceforth redundant and have no effect.</p>
<p>NB Support for <wbr> is new in mPDF 5.7</p>
</div>
<h3>Text circle</h3>
<div class="gradient text">
<p>Added in mPDF 5.6 but not included in New Features example - transparent background and Divider were new. Now also added support for font-size:auto</p>
<p class="code">
<textcircle r="30mm" top-text="Text Circular Text Circular" bottom-text="Text Circular Text Circular" divider="&bull;" style="font-size: auto" />

<li>List item number 2</li>
<li>List item number 3</li>
</ol>
</div>
<h3><dottab> and outdent</h3>
<div class="gradient text">
<p><dottab> now supports a custom CSS property "outdent", which can also be used as an HTML attribute i.e. <dottab outdent="2em"></p>
<p>The first item uses <dottab outdent="4em"> whereas the following items have <dottab class="menu"> (with CSS <code>dottab.menu{outdent: 4em;}</code> ) and all have padding-right="4em" on the <div> element</p>
<div style="border: 0.2mm solid #000088; padding: 1em;">
<p class="menu">Nulla felis erat, imperdiet eu, ullamcorper non, nonummy quis, elit. Suspendisse potenti. Ut a eros at ligula vehicula pretium. Maecenas feugiat pede vel risus. Nulla et lectus <dottab outdent="4em" /> £37.00</p>
<p class="menu">Fusce eleifend neque sit amet erat. Integer consectetuer nulla non orci. Morbi feugiat <dottab class="menu" /> £3700.00</p>
<p class="menu">Cras odio. Donec mattis, nisi id euismod auctor, neque metus pellentesque risus, at eleifend lacus sapien et risus <dottab class="menu" /> £27.00</p>
<p class="menu">Phasellus metus. Phasellus feugiat, lectus ac aliquam molestie, leo lacus tincidunt turpis, vel aliquam quam odio et sapien. Mauris ante pede, auctor ac, suscipit quis, malesuada sed, nulla. Integer sit amet odio sit amet lectus luctus euismod <dottab class="menu" /> £7.00</p>

</div>
<p></p>
<p class="code">
p.menu { text-align: justify; padding-right: 4em; }<br />
dottab.menu { outdent: 4em; }
</p>
<p>NB It is recommended to use &nbsp; after the dottab if a space is required before the following content.</p>
<p>NB This (outdent) is also used in the Table of Contents (see earlier in this document).</p>
</div>
<h3>Layers</h3>
<div class="gradient text">
<p>mPDF 5.7 will create layers in the document using the CSS property z-index. All layers are visible by default.</p>
<p>This demonstrates layers in a PDF document. Select the layers named "Correct Answers" or "Wrong Answers" in your PDF viewer (the layers pane should be open already in Adobe Acrobat)</p>
<div><b>What is the name of the Prime Minister of Britain?</b></div>
<div style="z-index:1;color: green;float: left; width:30%">David Cameron</div>
<div style="z-index:2;color: red;">Rupert Murdoch</div>
<div><b>What is the name of the David Beckham\'s bulldog?</b></div>
<div style="z-index:1;color: green;float: left; width:30%;">Scarlet</div>
<div style="z-index:2;color: red;">Victoria</div>
<p>To open/close/select layers in Adobe Reader (10):<br />
<img src="assets/layers_tab.jpg" /></p>
<p>The layer names and initial state can be set (optionally) e.g.</p>
<p class="code">
$mpdf->layerDetails[1][\'state\']=\'hidden\'; // Set initial state of layer - "hidden" or ""<br />
$mpdf->layerDetails[1][\'name\']=\'Correct Answers\';<br />
$mpdf->layerDetails[2][\'state\']=\'hidden\';<br />
$mpdf->layerDetails[2][\'name\']=\'Wrong Answers\';<br />
</p>
<p>This is the code used in the example above:</p>
<p class="code">
<div style="z-index:1;color: green;float: left; width:30%;">Scarlet</div><br />
<div style="z-index:2;color: red;">Victoria</div>
</p>
<div>To force the PDF reader to open with the layers tab open, set:
<p class="code">$mpdf->open_layer_pane = true;</p>
</div>
</div>
<h3>CSS visibility on <span></h3>
<p>CSS visibility:hidden is now supported on inline elements e.g. <span></p>
<div class="gradient text">
<p>This next bit of text is hidden - <span style="visibility:hidden; border:1px solid #880000;background-color:yellow">Hidden text</span> - and this isn\'t.</p>
<p class="code">style="visibility:hidden;"</p>
<p>This next bit of text is only visible in print - <span style="visibility:printonly; border:1px solid #008800;background-color:yellow">Hidden text</span> - and this isn\'t.</p>
<p class="code">style="visibility:printonly;"</p>
<p>This next bit of text is only visible on screen - <span style="visibility:screenonly; border:1px solid #000088;background-color:yellow">Hidden text</span> - and this isn\'t.</p>
<p class="code">style="visibility:screenonly;"</p>
<p>You can show or hide these elements as for layers (above).</p>
</div>
