css_xhtml theme

The css_xhtml theme provides all the basics that the simple theme provides and adds several features.

_ Standard two-column CSS-based layout, using <div> for the HTML Struts Tags (form, textfield, select, etc)

Wrapping the Simple Theme

The xhtml theme uses the “wrapping” technique described by Extending Themes. Let's look at how the HTML tags are wrapped by a standard header and footer. For example, in the textfield template, text.ftl, the controlheader.ftl and controlfooter.ftl templates are wrapped around the simple template.

{% highlight freemarker %} {% remote_file_content https://raw.githubusercontent.com/apache/struts/master/core/src/main/resources/template/simple/text.ftl %} {% endhighlight %}

CSS XHTML theme header

The header used by the HTML tags in the css_xhtml theme is complicated. Unlike the xhtml theme, the CSS theme does not use a labelposition attribute. Instead, the label position is defined by CSS rules.

{% highlight freemarker %} {% remote_file_content https://raw.githubusercontent.com/apache/struts/master/core/src/main/resources/template/css_xhtml/controlheader.ftl %} {% endhighlight %}

Note that the fieldErrors, usually caused by Validation, are displayed in a div block before the element is displayed.

CSS XHTML theme footer

And the controlfooter.ftl contents:

{% highlight freemarker %} {% remote_file_content https://raw.githubusercontent.com/apache/struts/master/core/src/main/resources/template/css_xhtml/controlfooter.ftl %} {% endhighlight %}

Special Interest

Two css_xhtml templates of special interest are head and form.

Head template

The css_xhtml head template is similar to the xhtml head template. The difference is that CSS is used to provide the layout. The contents of head.ftl are:

{% highlight freemarker %} {% remote_file_content https://raw.githubusercontent.com/apache/struts/master/core/src/main/resources/template/css_xhtml/head.ftl %} {% endhighlight %}

The head includes a style sheet. The contents of styles.css are:

{% highlight css %} {% remote_file_content https://raw.githubusercontent.com/apache/struts/master/core/src/main/resources/template/css_xhtml/styles.css %} {% endhighlight %}

Form template

The css_xhtml form template is almost exactly like the xhtml form template , including support for Pure JavaScript Client Side Validation. The difference is that instead of printing out an opening and closing <table> element, there are no elements. Instead, the CSS rules for the individual HTML tags are assumed to handle all display logic. However, as noted, client-side validation is still supported.

The only difference is that instead of printing out an opening and closing <table> element, there are no elements.
