| <p>The <em>css_xhtml theme</em> provides all the basics that the <a href="simple-theme.html">simple theme</a> provides and adds several features.</p> |
| |
| <p>_ Standard two-column CSS-based layout, using <code class="highlighter-rouge"><div></code> for the HTML <a href="struts-tags.html">Struts Tags</a> (<a href="form-tag.htmk">form</a>, |

| <h2 id="wrapping-the-simple-theme">Wrapping the Simple Theme</h2> |
| |
| <p>The xhtml theme uses the “wrapping” technique described by <a href="extending-themes.html">Extending Themes</a>. Let’s look at how |
| the HTML tags are wrapped by a standard header and footer. For example, in the <a href="textfield-tag.html">textfield</a> template, |
| <code class="highlighter-rouge">text.ftl</code>, the <code class="highlighter-rouge">controlheader.ftl</code> and <code class="highlighter-rouge">controlfooter.ftl</code> templates are wrapped around the simple template.</p> |
