<a href="themes-and-templates.html" title="back to Themes and Templates"><< back to Themes and Templates</a>
<h1 class="no_toc" id="simple-theme">simple theme</h1>
<ul id="markdown-toc">
<li><a href="#head-tag" id="markdown-toc-head-tag">Head Tag</a></li>
<li><a href="#simple-head-template" id="markdown-toc-simple-head-template">simple head template</a></li>
</ul>
<p>The simple theme renders “bare bones” HTML elements. The simple theme is most often used as a starting point for other
themes. (See <a href="extending-themes">Extending Themes</a> for more.)</p>
<p>For example, the <a href="textfield-tag">textfield</a> tag renders the HTML <code class="language-plaintext highlighter-rouge">&lt;input/&gt;</code> tag without a label, validation, error
reporting, or any other formatting or functionality.</p>
<blockquote>
<p>Both the <a href="xhtml-theme">xhtml theme</a> and <a href="css-xhtml-theme.xhtml">css_xhtml theme</a> extend the simple theme. Look
to them for examples of how to build on the foundation laid by the simple theme.</p>
</blockquote>
<h2 id="head-tag">Head Tag</h2>
<p>The simple theme <a href="head-tag">head</a> template prints out a javascript include required
for the <a href="dojo-datetimepicker-tag">datetimepicker</a> tag to render properly.</p>
<h2 id="simple-head-template">simple head template</h2>
<p>The <a href="simple-theme">simple theme</a><a href="head-tag">head</a> template only does one thing: it loads the minimal
Ajax/Dojo support so that tags can import Dojo widgets easily.</p>
<p>The source of the simple <code class="language-plaintext highlighter-rouge">head.ftl</code> template is:</p>
