One way to vertically center a line of text in a container div is to set line-height to be the same as the height of the container. But that requires specifying line-height in pixels. This technique avoids that.

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 ):

If CSS3 border-image is properly supported, making a rounded corner box is very easy. You just need a round corner image like this: The following markup:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" ...would render like this (try it in Firefox 3.5 and Google Chrome): However, IE as of version 8.0 does not support border-image . So until border-image is reliably supported in all major browsers, we still have to rely on tried and true tricks to make it work. In general, I found three general categories of tricks to make rounded corners: Good old tables. This trick creates a table of 9 cells and uses the 8 cells on the perimeter to render the borders and rounded corners. The central cell is used for...

cURL is a command line tool for transferring files with URL syntax. The main purpose and use for cURL is to automate unattended file transfers or sequences of operations. It's really easy to see HTTP headers with curl:

This is a script to tail a log file through the web browser. It uses AJAX, apache web server, mod_python, UNIX utilities tail (requires the --lines switch) and wc . The log file may reside on the web server or any other host accessible from the web server through SSH. Although it's written in python, it should be easy to port to other languages such as Perl. Apache httpd.conf :
