The default compressed MIME types are: text/html,text/xml,text/plain .
It would be nice to add other types:

By default Firefox puts a dotted line box around the link or button label when you click them. Sometimes it's annoying and makes your sexy buttons look ugly. You can get rid of the dotted lines for links with outline:none in CSS, but that doesn't work for buttons.

For buttons you need " button::-moz-focus-inner { border: 0; } ":

In an HTML page, elements can overlap because of position styles. When there's an overlap, elements coming later in the HTML code are displayed on the top. This can be altered by specifying z-index in the CSS. Elements with higher z-index are placed on the top.
However , z-index only works for elements that are not static positioned. Static positioned elements are always at the bottom compared to relative , fixed and absolute positioned elements.
This is a test page:
<!DOCTYPE html>
<html>
<head>
<style t...
Effects of z-index can be tested by adding it to the elements, for example:
<div id="bg" class="big" style="z-index: 3"></div>...

There are 4 positioning styles in CSS: static : this is the default positioning style. Elements are positioned according to the normal flow of the page. fixed : the element position is fixed relative to the browser window, i.e., when you scroll, the element does not move with other contents in the page. relative : the element is positioned relative to its normal position (i.e., static position). You can use relative positioning to offset an element from its normal position. Other elements are positioned as if the relative positioned element were in its normal position. absolute : the element is positioned relative to the first ancestor element that is not static positioned. If all ancestor elements are static positioned, the element is positioned relative to...

The events mouseover and mouseout are fired when the mouse enters/leaves the element where the event handlers are registered, and any nested elements which do not handle these events (because of event bubbling ). The events mouseenter and mouseleave are fired only when the mouse enters/leaves the specified element. Nested elements do not come into play. This following is a test page. You need Firebug to view the console output. Or use the JavaScript Executor bookmarklet. If none of these are available, an alert will popup (but you won't be able to fully test with alert.).

In this example I'll add a parameter to a facelets template. The example contains three tabs, each tab points to a different page. The tab control is shared among all pages, therefore, it is put in the template.
Starting from the simple facelet example , make these additions:
Create a new template WEB-INF/templates/tabs.xhtml :
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Stric...
Add a page for the about tab ( about.xhtml ):
<?xml version="1.0" encoding="UTF-8"?>
<ui:comp...
Add a page for the news tab ( news.xhtml ):
<?xml version="1.0" encoding="UTF-8"?>
<ui:comp...
Add a page for the partner tab ( partner.xhtml ):
<?xml version="1.0" encoding="UTF-8"?>
<ui:comp...
Build and re-deploy the application. Launch the browser and load page http://localhost:8080/facelet-demo/about.jsf .

Facelet templates can be nested, for example, a page can use a template which inherits from another template. To demonstrate this, let's start from the simple example and make these additions:
Add a place holder for CSS style sheets in WEB-INF/templates/default.xhtml :
<h:head>
<title>Facelets Template Demo</tit...
Add a derivative template ( WEB-INF/templates/default-style.xhtml ) which provides CSS:
<?xml version="1.0" encoding="UTF-8"?>
<ui:comp...
Add a page that uses the styled template ( home-style.xhtml ):
<?xml version="1.0" encoding="UTF-8"?>
<ui:comp...
The only difference between this file and home.xhtml is the template being used.
Compare the display of the pages home.xhtml and home-style.xhtml .

Both visibility:hidden and display:none hides an element in the DOM. But elements with visibility:hidden still takes up space, while display:none does not.
Example (click the divs to hide or show):
