| <h1 id="struts-tags">Struts Tags</h1> |
| |
| <p>The framework provides a tag library decoupled from the view technology. In this section, we describe each tag in general |
| terms, such as the attributes it supports, what the behaviors are, and so forth. Most tags are supported in all template |
| languages (see <a href="jsp-tags">JSP Tags</a>, <a href="velocity-tags">Velocity Tags</a>, and <a href="freemarker-tags">FreeMarker Tags</a>), |
| but some are currently only specific to one language. Whenever a tag doesn’t have complete support for every language, |
| it is noted on the tag’s reference page.</p> |
| |
| <p>The types of tags can be broken in to two types: generic and UI. Besides function and responsibility, the biggest |
| difference between the two is that the HTML tags support <em>templates</em> and <em>themes</em> . In addition to the general tag |
| reference, we also provide examples for using these generic tags in each of the support languages.s</p> |

| <p>Be sure to read the <a href="tag-syntax">Tag Syntax</a> document to learn how tag attribute syntax works.</p> |
