What

With omissions you never have to leave shorthand margin/padding syntax. CSS often forces you to leave shorthand even if you'd prefer not to. For instance you cannot specify just margin-top/margin-bottom.

Native CSS padding/margin shorthand syntax vs omissions:

.foo { margin : 4px 0; }    .foo { padding: 0 25px 46px; }    .foo { padding: 4px 0 0 17px; }

.foo { margin : 4px _; }    .foo { padding: _ 25px 46px; }    .foo { padding: 4px _ _ 17px; }

Omissions allow you to skip values, whereas CSS forces you to assign something.

Why

• It makes writing your CSS more fun
• Collecting all padding or margin side properties (top/right/bottom/left) on one line helps readers visually scan for dimensions information.
• In my experience writing CSS can be a verbose, repetitive, and fatiguing experience; small effecientcy wins like ommissions will eventually make the load noticably lighter
• Writing margin: 4px 0 0 17px; when you don't actually need those zeros is error-prone, especially when using modern OOCSS patterns that break styling across discrete classes because 0 on a generic class might blow away an actually meaningful unit on another generic class. It is also a diservice to readers and logic to provide meaningless data for the sake of shorthand syntax.
