Sometimes when editing a rule you may end up defining multiple properties that can better be represented using shorthand. For example:

.mybox {
    margin-left: 10px;
    margin-right: 10px;
    margin-top: 20px;
    margin-bottom: 30px;

Using shorthand properties where possible helps to decrease the overall size of the CSS.

How do I fix this ?

These four properties can actually be combined into a single margin property, such as:

.mybox {
    margin: 20px 10px 30px;

Similarly, padding-top, padding-right, padding-bottom and padding-left can be combined to a single padding shorthand property.
