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. }

Not specifying a unit for length values is a very common mistake among CSS beginners. In HTML you can get away with that, but in CSS all length values must have a unit. There are two exceptions: line-height and 0 (zero) values. Note that the value must be immediately followed by the unit – do not insert a space between them.

There is no need to specify a unit for 0 (zero) values because zero pixels equals zero centimeters equals zero of any other length unit. Despite this it’s very common to see something like padding:0px where padding:0 would do.

While there’s nothing wrong with specifying a unit when the value is 0, it’s a waste of space and – at least to me – looks untidy.
