Features

Use old CSS

.element {
  letter-spacing: 2px;
  background-color: #1C6BA0;
}

If all your CSS declarations are on separate lines you don’t have to change anything

Remove colons

.element {
  letter-spacing 2px
  background-color #1C6BA0
}

In CSS-On-Diet colons and semicolons are optional

Use mnemonics

.element {
  les 2p
  bac #1C6BA0
}

Common CSS keywords have mnemonics. Parameters are 3 letters long, values 2, and units just 1 letter (The list)

Medias Breakpoints

@cod-media {
  tablet (min-width: 768px)
}
.element {
  les 2p
  les 3p @tablet
}

Responsive Web Design was never so easy and intuitive

One line comments

.element {
  les 2p // why not 3?
  bac #1C6BA0 // deep ocean
}

No need to remember to close those comments

Nested comments

.element {
  /*
  les /*3p*/ 2p
  */
  bac #1C6BA0
}

Now you can comment out code with other comment inside. Finally…

Arithmetics

.element {
  les 3p-1
  bac #1C6BA0
}

CSS needs calculations. That’s more than sure.

Short RGBA

.element {
  les 3p-1
  bac #1C6BA0F1
}

Just two more digits and you have transparency with your color

Variables

@cod-defines {
  sp2014 3p-1
  ocean #1C6BA0F1
}
.element {
  les sp2014
  bac ocean
}

Defines are like variables. Write it once and use it anywhere. Stay DRY!

Mixins

@cod-defines {
  sp2014 3p-1
  ocean bac #1C6BA0_ARG1_ ;\
        bai url("fish.png")
}
.element {
  les sp2014
  ocean(F1)
}

Mixins can be anything placed anywhere. Arguments give them programming power.
