More, a CSS Compiler

Hop right in and use it

On Windows: More <input file>

On OS X Or Linux: mono More <input file>

Mono is a requirement for OS X and Linux, get it here

On Windows, .NET 4.0+ is required. You probably already have it, if not it's available via Windows Update.

For more options, More /? or mono More /?.

Be Aware

More does away with subsequent CSS declarations overriding previous ones. To force some CSS to appear at the start of a file, use @reset { ... } blocks as detailed below.

This means it is legal to refer to anything (selectors, mixins, variables) before they are declared unless explicitly noted otherwise.

Features

Nesting

.my-class {
  foo: bar;
  .sub-class {
    fizz: buzz;
  }
}

becomes

.my-class {
  foo: bar;
}
.my-class .sub-class {
  fizz: buzz;
}

Variables

@a = 10px;
.my-class {
  width: @a;
}

becomes

.my-class {
  width: 10px;
}

Variables are immutable once declared.

In String Replacements And Math

@a = 10px;
@b = 90;
.my-class {
  width: @a * 2;
  filter: progid:DXImageTransform.Microsoft.MotionBlur(strength=9, direction=@b);
}

becomes

.my-class {
  width: 20px;
  filter: progid:DXImageTransform.Microsoft.MotionBlur(strength=9, direction=90);
}

More makes a best effort to parse the right-hand side of properties for meaning, and failing that will fall back to string replacements. More tries hard to accept all valid CSS as is.

More will coerce units where it makes sense, 10cm + 10mm will resolve to 11cm for example. More will error if it is asked to perform a conversion that doesn't make sense, #fff + 10in for example. You can remove unit information from values with the @nounit built-in function.

Mixins

@my-mixin(@c) {
  color: @c;
  width: 10px;
}
.my-class {
  @my-mixin(green);
}

becomes

.my-class {
  color: green;
  width: 10px;
}

Mixin parameters can be required, have default values, or be completely optional (and must be declared in that order).

@my-mixin(@required, @hasDefault=value, @optional?) { ... }

To you can pass parameters by name like so:

img {
  @my-mixin('required's value', @optional=value);
}

Note that properties using optional parameters are themselves considered optional, by way of example.

@mixin(@optional?) { color: red; height: @optional; }
a {
  @mixin();
}

becomes

a {
  color: red;
}

Despite the height: @optional; property not having a wrapping (...)?, as would normally be expected. More details on optional properties below.

Optional Variables and Mixins

It's possible to coalesce over missing values using the ?? operator, and omit missing mixins with a trailing ?. This is useful for working with overrides. Whole properties can be omitted if enclosed in parenthesis with a trailing ? if they depend on variables that haven't been defined.

// notice @c, @h, and @missing-mixin aren't declared
.my-class {
   color: @c ?? blue;
   @missing-mixin()?;
   height: (123px + @h)?;
}

becomes

.my-class {
  color: blue;
}

Includes

More adds a @using directive to copy CSS and More from other files. @include is still available to merely refer to other CSS files, but using it is not suggested. @using accepts media queries, just like @include.

For example:

@using 'my.css' only tv and (width: 200px);

Sprites

@sprite('/sprite.png'){
  @up = '/up.png';
  @up-glow = '/up-glow.png';
}

Writes a sprite file to /sprite.png (relative to the output file) containing /up.png and /up-glow.png, and creates two mixins @up and @up-glow.

You can use them like so:

.up-arrow {
  @up();
  &:hover {
    @up-glow();
  }
}

To produce

// The background-position, width, and height values will vary depending on the images naturally
.up-arrow {
  background-image: url(/sprite.png);
  background-position: 0px 0px;
  background-repeat: no-repeat;
  width: 20px;
  height: 20px;
}
.up-arrow:hover {
  background-image: url(/sprite.png);
  background-position: 0px -20px;
  background-repeat: no-repeat;
  width: 20px;
  height: 20px;
}

Copy CSS by Selector

You can use @(<selector>) to copy whole blocks without having to declare a mixin.

.class {
  width:10px;   
}
.other-class {
  @(.class);
  height: 10px; 
}

becomes

.class {
  width:10px;
}
.other-class {
  width:10px;
  height: 10px;
}

Explicit Overrides

When importing properties using selectors or mixins you can explicitly request that rules in the include override rules in the containing block with a trailing !.

@alarm-mixin() {
  color: red;
  font-weight: bold;
}
.my-class {
  color: #eee;
  line-height: 110%;
  @alarm-mixin()!;
}

becomes

.my-class {
  color: red;
  font-weight: bold;
  line-height: 110%;
}

More expects overriding to be intentional, and will warn if the same property appears in a block twice.

Reset Blocks

CSS contained in @reset { ... } will appear at the top of a CSS file, and make it available for "resetting" other blocks.

@reset {
  a { color: blue; }
}
p {
  font-size: 14px;
  a { reset(); }
}

becomes

a { color: blue; }
p { font-size: 14x; }
p a { color; blue; }

Note that @reset() operates on the inner-most selector of nested blocks.

To explicitly reset to a different selector, pass it.

@reset {
  a { color: blue; }
}
p { @reset(a); }

becomes

p { color: blue; }

Builtin Functions

  • blue(color)
  • darken(color, percentage)
  • desaturate(color, percentage)
  • fade(color, percentage)
  • fadein(color, percentage)
  • fadeout(color, percentage)
  • gray(color)
  • green(color)
  • hue(color)
  • lighten(color, percentage)
  • lightness(color)
  • mix(color, color, percentage/decimal)
  • nounit(any)
  • red(color)
  • round(number, digits?)
  • saturate(color, percentage)
  • saturation(color)
  • spin(color, number)

Built-in functions must be invoked with a leading @, color: @saturate(green, 10%) for example. rgb, rgba, and hsl are not considered built-in functions.

More is a CSS Superset

All CSS 2.1 and most CSS 3 features are available in More, including @import, @charset, @media, @font-face, and @keyframes.

Note that within @media, @keyframes, and @font-face it is illegal to declare new mixins.

Within @media queries, @(<selector>) will search for matches within the @media statement before searching the rest of the file; and will only search outside the @media query if it does not find a match. @(<selector>) outside of a @media statement will never search within one.

Something went wrong with that request. Please try again.
