#Luigi (v2.2.0)
Jump to the index to everything that is included.
Luigi is the Scss library developed by the developers at Bozboz and the rest of the world. It takes influence from the most popular of libraries and includes most of the popular mixins, plus some extra Bozboz crafted ones. A full list of libraries and credits can be found in the appendix
All mixins are included into the main _luigi.scss. This is so in your app.scss or style.scss you can just include _luigi.scss to benefit from the whole shebang.
When adding mixins to existing or new files, please ensure that they are placed in alphabetical order within the file
Luigi is laid out folders categorising the library:
Alternatively, see the Full Luigi Index for everything included.
##Helpers
The helpers folder includes the following files:
###Base Vars
This lays out all the variables that can be overwritten throughout Luigi. Defaults are set here:
$base-font: Arial,sans-serif !default;
This sets the body and all inputs to the declared font
$base-font-size: 12px !default;
The default font size for the website
$base-gutter: 15px !default;
or
$gutter: $base-gutter !default;
The default gutter - this is used as the margin bottom for things such as <p> and headings
$gap: $gutter*2 !default
Generic space for paddings
$grid-gap: $gutter !default
Include the Luigi grid for older versions:
$luigi-grid: false !default;
Used as the margin for grid items
$debug-mode: false !default;
Whether or not debug mode is enabled (see information about Debug).
$image-fallback-extension: 'png' !default;
Used with the background-image and image-2x to append the 'png' extension to the filename.
$image-path: '/images' !default;
This sets the default image folder for the mixins in mixins/_images.scss.
$image-retina-suffix: '@2x' !default;
This is the retina suffix for retina images.
$global-box-sizing: true !default;
This determines whether the site uses global border-box as its box model (see the Box Sizing file).
$sprite: false !default;
Used with the sprite mixin to set a base path for the image sprite.
$sprite-size: 0 0 !default;
Used with the image-2x mixing in the image file to set the original sprite-size (at 72ppi).
$sticky-footer-height: false !default;
$sticky-footer-margin: $sticky-footer-height !default;
These are for the sticky footer predefined file - read about the Sticky Footer.
###Debug
This file outlines any basic problems you might have in your html. Using some advanced selectors it outlines elements with things such as alt tags missing or direct descendants of uls which are not lis.
This can be enabled by:
$debug-mode: true;
This originates from Inuit (see Appendix 2.1)
This is a basic print stylesheet - taken from Stu Robson's sassifaction (see Appendix 2.3). It applies some very basic layout modifications when printing
##Layout
This includes the Foundation Grid and the optional Luigi grid.
##Mixins
The mixins folder comprises of:
###Image
The image mixin file contains:
####background-image
Background-image is a mixin which uses SVG background images with PNG and retina fallback. This mixin require Modernizr.
Mixin:
background-image($name, $size:false)
$name: The filename
$size: The background size
Usage:
.class {
@include background-image(sprite, 50px 100px);
}
Output:
.class {
background-image: url(/images/sprite.svg);
background-size: 50px 100px;
}
.no-svg .class {
background-image: url(/images/sprite.png);
}
@media only screen and (-moz-min-device-pixel-ratio: 1.5), only screen and (-o-min-device-pixel-ratio: 3 / 2), only screen and (-webkit-min-device-pixel-ratio: 1.5), only screen and (min-device-pixel-ratio: 1.5) {
.no-svg .class {
background-image: url(/images/sprite@2x.png);
}
}
####image-2x
This mixin will get the high resolution image for retina displays. The retina images are twice as big with @2x appended in the name.
Mixin:
image-2x($name, $image-size: $sprite-size)
$name: The filename
$image-size: The original sprite size (at 72ppi)
Usage:
$sprite-size: 50px 100px;
.class {
@include image-2x(sprite);
}
Output:
@media (-moz-device-pixel-ratio: 1.5), (-o-min-device-pixel-ratio: 3 / 2), (-webkit-min-device-pixel-ratio: 1.5), (min-device-pixel-ratio: 1.5), (min-resolution: 1.5dppx) {
.class {
background-image: url(/images/sprite@2x.png);
background-size: 50px 100px;
}
}
####sprite
This makes using a sprite in a project easier and less to code - a sprite path is specified and then the mixing included. Needs to be used with the $sprite var.
Mixin:
sprite($width, $height, $bg-extras)
$width: The width of the image
$height: The height of the image
$bg-extras: The location of the image on the sprite & any other
Usage:
$sprite: '/images/sprite.png';
.class {
@include sprite(25px, 20px, 0 0);
}
Output:
.class {
width: 25px;
height: 20px;
background: url("/images/sprite.png") no-repeat 0 0;
}
###Layout
The layout mixin file contains:
####abs
The abs mixin has server variants allowing for quick absolute positioning.
Mixin:
abs-tl($top: $base-gutter, $left: $base-gutter)
abs-tr($top: $base-gutter, $right: $base-gutter)
abs-bl($bottom: $base-gutter, $left: $base-gutter)
abs-br($bottom: $base-gutter, $right: $base-gutter)
$top/$bottom/$left/$right: Where you want the element positioned (defaults to $base-gutter)
Usage:
.class {
@include abs-tl();
}
.class-alt {
@include abs-br(20px, 5%);
}
Output:
.class {
left: 15px;
position: absolute;
top: 15px;
}
.class-alt {
bottom: 20px;
left: 5%;
position: absolute;
}
####columns
Columns is a simple mixin which allows the use of css3 columns
Mixin:
columns($cols: 2, $gap: $base-gutter)
$cols: Number of columns you want the text split into
$gap: The gap between the columns
Usage:
.class {
@include columns(3, 10px);
}
Output:
.class {
column-count: 3;
column-gap: 10px;
}
####vertical-center
Align vertically an element to center of a parent element
Mixin:
vertical-center($position: relative)
Output:
.class {
position: relative;
top: 50%;
transform: translateY(-50%);
}
####absolute-middle
Align vertically and horizontally an element to center of a parent element
Mixin:
absolute-middle()
Output:
.class {
left: 50%;
position: absolute;
top: 50%;
transform: translate(-50%, -50%);
}
###Modular
This file contains modular classes which can be used in the SCSS or within your HTML and, as such, do not take parameters. To see what each mixin does - view modular.scss
####class
This encourages more modular class naming approach and will match class names that are an extension of the base class. You passi in a class name (for example button) and will be inherited by variations (e.g. button-alt will inherit button class) - see the example on Codepen
Mixin:
class($class)
Usage:
@include class(button) {
font-size: red;
}
Output:
[class*="button"] {
font-size: red;
}
####clearfix
This adopts the clearfix hack as described by Chris Coyier
####reset
This completely resets an element and strips it of its margin, padding, border and background.
####secret-list
This allows the semantic use of a ul and li without the styles.
Clearfix, reset and secret-list are all placeholder selectors and should be used with an extend. E.g:
@extend %clearfix;
####unselectable
Disables users being able to select, helps with stopping clicks autoselecting areas
@extend %unselectable;
###Pseudo
The pseudo file contains mixins which affect or add a pseudo element(s)
####placeholder
For styling the placeholder text in a form field
Mixin:
placeholder {
@content
}
@content: The styling for the input
Usage:
.class {
@include placeholder {
color: #666;
}
}
Output:
.class::-webkit-input-placeholder{
color: #666;
}
.class:-moz-input-placeholder{
color: #666;
}
.class::-moz-input-placeholder{
color: #666;
}
.class:-ms-input-placeholder{
color: #666;
}

@include truncate-text;
}
Output:
.class {

}
##Predefined
The predefined folder contains blocks of CSS which have a function - almost like a library of tricks.
###Box Sizing
This is the global box sizing, which gives every element a box model of border-box
This is automatically turned on in Luigi, but can be turned off by adding the following to your variables file:
$global-box-sizing: false;
###Sticky Footer
predefined/_sticky-footer.scss
This is the code to have a sticky footer (see Appendix 2.5) on your website.
Usage:
$sticky-footer-height; 100px; // The height of your footer
If the margin on the body needs to be more or less than the height of the footer, a second variable can be declared:
$sticky-footer-margin: 120px;
