<p>Lets you create HTML heading tags. The first parameter will contain the
data, the second the size of the heading. Example:</p>
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">echo</span> <span class="nx">heading</span><span class="p">(</span><span class="s1">'Welcome!'</span><span class="p">,</span> <span class="mi">3</span><span class="p">);</span>
</pre></div>
</div>
<p>The above would produce: <h3>Welcome!</h3></p>
<p>Additionally, in order to add attributes to the heading tag such as HTML
classes, ids or inline styles, a third parameter accepts either a string
or an array:</p>
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">echo</span> <span class="nx">heading</span><span class="p">(</span><span class="s1">'Welcome!'</span><span class="p">,</span> <span class="mi">3</span><span class="p">,</span> <span class="s1">'class="pink"'</span><span class="p">);</span>

<p>Lets you create HTML <img /> tags. The first parameter contains the
image source. Example:</p>
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">echo</span> <span class="nx">img</span><span class="p">(</span><span class="s1">'images/picture.jpg'</span><span class="p">);</span> <span class="c1">// gives <img src="http://site.com/images/picture.jpg" /></span>
</pre></div>
</div>
<p>There is an optional second parameter that is a TRUE/FALSE value that
specifics if the <em>src</em> should have the page specified by
<code class="docutils literal"><span class="pre">$config['index_page']</span></code> added to the address it creates.
Presumably, this would be if you were using a media controller:</p>
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">echo</span> <span class="nx">img</span><span class="p">(</span><span class="s1">'images/picture.jpg'</span><span class="p">,</span> <span class="k">TRUE</span><span class="p">);</span> <span class="c1">// gives <img src="http://site.com/index.php/images/picture.jpg" alt="" /></span>
</pre></div>
</div>
<p>Additionally, an associative array can be passed to the <code class="docutils literal"><span class="pre">img()</span></code> function
for complete control over all attributes and values. If an <em>alt</em> attribute
is not provided, CodeIgniter will generate an empty string.</p>
<p>Example:</p>
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$image_properties</span> <span class="o">=</span> <span class="k">array</span><span class="p">(</span>

<p>Lets you create HTML <link /> tags. This is useful for stylesheet links,
as well as other links. The parameters are <em>href</em>, with optional <em>rel</em>,
<em>type</em>, <em>title</em>, <em>media</em> and <em>index_page</em>.</p>
<p><em>index_page</em> is a boolean value that specifies if the <em>href</em> should have
the page specified by <code class="docutils literal"><span class="pre">$config['index_page']</span></code> added to the address it creates.</p>
<p>Example:</p>
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">echo</span> <span class="nx">link_tag</span><span class="p">(</span><span class="s1">'css/mystyles.css'</span><span class="p">);</span>
