# StandardKit Styles
SCSS Framework for the StandardKit Design & Component System
## Principles
The idea of StandardKit is based on a collection of thoughts and issues with the state of SCSS Frameworks, Component
Libraries & UI Kits. To name a few:
- It should be easy to use
- It should look good by default
- It should take into account accessibility & other web-standards
- I want to customize variables like colors, margins or corners
- I want to add my own custom flavors
- I should be able to easily override anything (without !important)
- I should be able to extend it and add my own behaviour
- I should be able to solve problems in my or my teams way of working
- It should guide me in the right direction
- I do not want to repeat myself
- HTML should be clean & simple to use
- I don't want any boilerplate code, I just want exactly what I need in my bundle
- I want good documentation where I can find specifically what EVERYTHING does
- I should be able to quickly build something with it
- Different parts of the framework should work as they do elsewhere
All of this is meant to put the developer first. You should be able to quickly & easily design & build quality
applications for your users.
This makes StandardKit a great fit for Rapid Prototyping but also prepared for expansion.
These ideas distill into the four main principles to which we validate our framework.
### Defaults & Standards
Everything should look & work simply by default. It uses standards to give you multiple way of doing things while
remaining consistent & straight-forward.
Easy way to style a button:
```html
Click
```
An example of standards: Modifiers work the same across components.
```html
Click
Message
```
Just an example, it is possible with configuration to set `padding--xl` for all alerts by default
### Multi-Path Solutions
There are no one-way solutions. Instead, we provide utilities for different strategies.
If you find a strategy, perspective or solution that is missing, let us know!
### Cascading Configuration
Everything should be configurable and cascade on multiple levels.
```scss
// configuration.scss
$components: (
button: (
default-color: primary,
save: (default-color: success, default-fill: outline),
cancel: (extend: save, default-color: error)
)
);
```
```html
Button
Save
Cancel
```
Here, the `cancel` button extends and overwrites the `save` button, which overwrite the `default` button.
### Built-to-Extend
Everything should be easily extendable, we even expect you to add your own customizations.
```scss
// Adding a custom color
$colors: (
custom: #abcdef
);
// Extending the button and adding behaviour
@extend .button--custom
{
border-radius: 1rem;
transition: background-color 2s ease-out;
}
```
## Modifiers, Flavors, Components & Types
### Modifiers
A modifier is a characteristic that can be modified. Something that you can change. Examples are:
- `color`
- `fill`
- `margin`
Example selection, please check the documentation website for a full list.
All modifiers work the same from the outside. For example to apply a different `padding` to a component, you would say:
```html
A div with padding 'xl'
```
As you can probably tell, we use two hyphens (BEM-style) to select an alternative.
### Flavors
Modifiers can have a number of flavors defined. For example:
```scss
$color: (
error: red,
warning: orange,
info: blue,
success: green
);
```
This is a simplified example. Check the `theme` for the actual values.
### Custom Flavors
There are two types of modifiers; `static` & `configurable`.
#### Static Modifiers
An example of a `static` modifier is:
- `case` (`lowercase`, `uppercase` `capitalized`).
Since there is a limited / hardcoded number of options here, it doesn't make sense to expand.
If however you feel that there is a usecase to expand on one of the static modifiers,
please create an issue and let us know!
StandardKit is never perfect and you should be able to use it the way you want it.
#### Configurable Modifiers
Most modifiers are configurable. This means that you can add your own flavors, as well as override pre-defined ones. For
example:
```scss
// Override the error color to 'purple' and adding our own 'custom' color
$colors: (
error: purple,
custom: hotpink
);
```
Now you could use this the following way:
```html
My custom colored div
```
### Components
A component (e.g. `alert` or `button`) usually has a number of modifiers available. For instance, let's look at
the `button` component.
```html
Click me
```
Next to the modifiers that you can see are being set here, like `padding--xs`, the component also has a number of
default modifiers. As you might have expected from StandardKit, you can override / configure this. For example:
```scss
$components: (
button: (
default-color: primary,
default-margin: xl,
default-padding: xs
)
);
```
Now, you can just use:
```html
I am a configured button
```
This becomes useful when you have more buttons scattered through-out your application.
### Types
Most of the time, applications tend to have multiple definitions of a button. For example, we might have a `cta-button`,
a `save-button` and a `cancel-button`. Using just the component configuration, you can only optimize for one situation.
With types, we don't have to.
##### Types are a compound component definition that combines multiple modifiers on top of the default modifiers
For example:
```scss
$components: (
button: (
default-color: primary,
cta: (default-color: custom, default-margin: xl),
save: (default-padding: xs),
cancel: (default-color: error)
)
);
```
To now use these three buttons, I can just:
```html
Call-to-Action
Save
Cancel
```
Very simple yet powerful.
### Special Cases
A couple of modifiers are special.
#### Color & Fill Combo
This is relevant because `color` depends on `fill`.
For instance, with a `fill: 'fill'` the `text` color is the `contrast` color and the `background` is the `main` color.
See `Color Generation` for more information about colors and their (generated) subsets.
#### Complex Modifiers
Some modifiers can be configured a little bit more than others. For example:
```scss
// Colors
$colors: (
primary: #fff,
secondary: (main: #fff, complement: #f00, contrast: #000, complement-contrast: #0ff)
);
// Elevation
$elevation: (
high: 20,
custom: () // TODO : Implement
);
```
In this case all values are optional, but you need at least `main` or `complement` to generate the others.
#### Breakpoints
Breakpoints are configurable modifiers, you can add or change them to your liking.
By default it's using `em` but feel free to change to what you want.
However, sometimes you want to change the behaviour of other modifiers based on the viewport. For example:
```scss
$margins: (
custom: (start: square, s: 3rem, l: round)
)
```
As you can see, something weird is going on. I'm using `round` which is one of the flavors, but I'm also
specifying `3rem`, an actual value. This always looks for the flavor first. So it would be unwise to call a flavor by
one of the values.
StandardKit uses the `start` keyword to distinguish if this is a breakpoint-scenario. This is only needed in case of
complex modifiers, like `color` or `elevation`.
##### This means that StandardKit is 'mobile-first'
## Configuration
### Theme Options
A list of the default theme options.
```scss
$options: (
prefer-dark-colors: false,
exclude-default-theme-selector: false,
contrast-threshold: 42%,
contrast-value-percentage: 2%,
complement-value-percentage: 7%,
brightness-weights: (
red: .229,
green: .576,
blue: .119
),
include-fonts : true or false, // default: true
merge-modifiers: 'replace' or 'merge', // default: merge
modifier-sets: 'none' or 'minimal' or 'basic' or 'all' // default: all
)
```
### Modifier Options
```scss
$configuration: (
color-options: (
set: 'none' or 'minimal' or 'basic' or 'all',
exclude: [],
include: [],
merge: 'merge' or 'replace'
)
)
```
## Modifiers
Below is a list of all modifiers and their default flavors. The values in the format are placeholders, check the theme
reference for actual values.
### Configurable Modifiers
#### Complex ( e.g. #fff or (main: #fff, contrast: #000) )
- color
- fill
- elevation
- breakpoint
- animation
#### Dynamic ( value based e.g. 1rem )
- corner
- border
- font
- font-import
- margin
- padding
- size
- width
### State ( combines other modifiers on state e.g. different fill on hover )
- active
- disabled
- focus
- hover
## Static
For these modifiers you can not add your own flavors. However, you can of course still in- or exclude certain sets or
individual standard flavors.
- alignment
- case
- highlight
- position
- vertical-alignment
### Complex Modifiers
| Modifier | Format | Description |
|---|---|---|
| |
color | #fff, red
(
main: #fff,
complement: #fff,
contrast: #fff,
complement-contrast: #fff
) | A single color or a color map. all values of the map are optional, but it needs at least a main or a complement to generate the rest.
fill | (
text: main,
border: contrast,
background: complement
) | The way color is used to fill elements.
elevation |
