Working with Multiple Style Sheets (Page 1 of 4 )
As the Web evolves steadily, more and more sites are providing their visitors with different mechanisms for customizing their surfing experience. Nowadays, it's quite common to visit a web site that allows users to change background and foreground colors of specific sections of that site, alter the size of the font, or even modify the position of certain elements by implementing "draggable" user interfaces.
Definitely, this level of customization is more evident when visitors are allowed to modify (only partially) the visual appearance of a given web site. This implies the existence behind the scenes of an application that manipulates the CSS styles associated with the web site.
Of course there are different approaches that can be used for changing the CSS styles of a specific web site. These range from the modification of a few elements to altering the visual appearance of the entire web document. However, one of the most popular techniques used these days takes advantage of multiple style sheets, which can be alternated by the mean of some embedded tools provided by the web surfer's own browser (Mozilla Firefox is a good example of this) and via server/client-side scripting.
As you can see, providing users with the capacity for swapping complete style sheets can be quite useful in certain cases, particularly if you're trying to make your web site more customizable and accessible to your visitors. Definitely, you'll have to agree with me that the topic is not only interesting, but implies learning different approaches to changing the style sheets of a given web document.
So, assuming that you might want to learn different methodologies for switching complete style sheets, in this series, which is made up of three tutorials, I'll be demonstrating with numerous easy-to-follow examples how to alternate between the distinct style sheets assigned to a selected web document. This will provide you with the required background to incorporate this capacity into your own web applications.
With the preliminaries already out of the way, let's learn together how to manipulate several style sheets attached to a given web page. You won't disappointed, trust me!
