+/**
+ * TWebControl class
+ *
+ * TWebControl is the base class for controls that share a common set
+ * of UI-related properties and methods. TWebControl derived controls
+ * are usually corresponding to HTML tags. They thus have tag name, attributes
+ * and body contents. You can override {@link getTagName} to specify the tag name,
+ * {@link addAttributesToRender} to specify the attributes to be rendered,
+ * and {@link renderContents} to customize the body content rendering.
+ * TWebControl encapsulates a set of properties related with CSS style fields,
+ * such as <b>BackColor</b>, <b>BorderWidth</b>, etc.
