Many exciting new functions and features are being thought up for CSS3. I will try and showcase some of them on this page, when they get implemented in either Firefox, Opera or Safari/Webkit.

By far the two most common types of fonts currently used on the Web are the serif font, Times New Roman (TNR) and the sans serif font, Arial. The question is, which one is more legible and at which size? In the past, it has been determined that serif fonts, which have ornamental strokes at the tip and base of each letter, are easier to read on paper than sans serif fonts, which do not have serifs. This is because it is believed that serifs help distinguished each individual letter (Albers, 1963). However, this benefit may be reduced or even eliminated on computer screens because of their display particularities, like poorer screen resolution and aliasing or "jaggies," as it is commonly known...

Here is a list of sample codes to show different ways to create windows and dialogs. You can view source of each example, even edit it and test your modification immediatly in your browser. Just click again on the link to open a new window/dialog with the modified code. Each window uses a javascript function to get a new id and DO NOT call setDestroyOnClose(). You can open the debug window if you want to see some debug outputs...

Everyday, we look at dozens of websites. The structure of these websites is defined in HTML, the lingua franca for publishing information on the web. Your browser's job is to render the HTML according to the specs (most of the time, at least). You can look at the code behind any website by selecting the "View source" tab somewhere in your browser's menu. HTML consists of so-called tags, like the A tag for links, IMG tag for images and so on. Since tags are nested in other tags, they are arranged in a hierarchical manner, and that hierarchy can be represented as a graph. I've written a little app that visualizes such a graph, and here are some screenshots of websites that I often look at.

a 'F' di Fjax sta per 'Flash'. Non aspettatevi però di trovarvi di fronte a filmatini accattivanti ed effetti super-cool. Si tratta infatti di una tecnica crossbrowser per effettuare l'aggiornamento dei contenuti di una pagina senza refresh (in stile AJAX) che usa Flash semplicemente come motore di parsing per trasformare XML in (X)HTML. Quoto dalla pagina di presentazione...

In questo tutorial vedremo come incorporare il celebre servizio Google Maps ad una pagina web. Il codice è allineato alle seconda versione della API di Google Maps. Il servizio è disponibile gratuitamente ma occorre avere una API Key, ovvero un codice alfanumerico che identifica univocamente l'URL (o una sottopagina di questo URL) che andrà ad utilizzare le mappe...

A weird behavior of Internet Explorer for Windows regarding image alt attribute makes web designers and developers to think that image’s alt attribute was meant to associate a tool-tip text for an image resource. Instead, alt attribute should be used by the browser as a placeholder when the image is not yet loaded or not available (think about screen readers or text-only browsers).
If you want to display a tool-tip while user hovers her mouse on the image just use the title attribute, as shown in the example below.
< img src="sea.jpg" width="300" height="200" alt="Sea photo" title="Hawaian sea, April 2003">
