You can often eliminate the need to specify a value for a property by taking advantage of that property’s default value. This is especially important to consider when you use shorthand properties, since any unset properties are assigned the default values of the corresponding individual property.

Some common default values are 0 for padding (though there are exceptions to this), and transparent for background-color.

Since there are slight differences in the default values between browsers, some people like doing a Global white space reset by zeroing both margin and padding for all elements at the top of their stylesheets:

1. * {
2. margin:0;
3. padding:0;
4. }

JavaScript is not a programming language in strict sense. Instead, it is a scripting language because it uses the browser to do the dirty work. If you command an image to be replaced by another one, JavaScript tells the browser to go do it. Because the browser actually does the work, you only need to pull some strings by writing some relatively easy lines of code. That’s what makes JavaScript an easy language to start with.

But don’t be fooled by some beginner’s luck: JavaScript can be pretty difficult, too. First of all, despite its simple appearance it is a full fledged programming language: it is possible to write quite complex programs in JavaScript. This is rarely necessary when dealing with web pages, but it is possible. This means that there are some complex programming structures that you’ll only understand after protracted studies.

Secondly, and more importantly, there are the browser differences. Though modern web browsers all support JavaScript, there is no sacred law that says they should support exactly the same JavaScript. A large part of this site is devoted to exploring and explaining these browser differences and finding ways to cope with them.

So basic JavaScript is easy to learn, but when you start writing advanced scripts browser differences (and occasionally syntactic problems) will creep up.
