# Private¶

Note

Let’s have a closer look at the Sass setup within /private and explain how we structured the code in there. These principles can be expanded to other preprocessors options such as Less or HAML.

Every folder within /private/sass has a file called _all.scss. This file ultimately gets imported by /private/sass/base.scss which gets compiled into /static/css/base.css. Update the _all.scss file to include additional modules. To keep the file simple, do not include files directly within base.scss.

Let’s cover the folders individually:

If a component is plug-and-playable, it probably belongs in here. Good examples are jQuery plugins or Aldryn addons. Sometimes larger application such as a shop might also be pluggable. If this is not the case, they belong in the /sass/sites directory.

Warning

You will always encounter the question whether to place a component within /sass/addons or /sass/sites. In case of doubts, use the sites folder.

## layout/¶

We consider the general look and feel as the layout of a website or application. This might include the typography, header and footer, icons or the printable version. The layout can be broken down into further parts if a website gets very large. We advise in general against this strategy and rather prefer to use /sass/sites to create specific layouts and derive from a global common style guide.

Warning

Everything that targets a specific element, such as custom styles for Bootstrap components or a specific form error, belongs in /sass/addons or /sass/sites.

## libs/¶

All independent files are placed within this folder. This implies that the order of inclusion does not matter within /sass/libs/_all.scss.

Hint

Libraries are, in their very core, plug-and-playable. The main difference between libraries and other plug-and-play components is, that if a library is removed, things will break.

## mixins/¶

This folder is used to store additional functions or mixins which are not part of the default bootstrap eco-system.

We provide already some helper functions such as em(12px, 16px) that calculates the pixel values from a given size in relation to the parent size.

Additionally we have mixins for managing z-index layers, keyframes rendering , hide-content and a simplified micro-clearfix.

## settings/¶

It is very useful to store values, that are used more than twice, within their own variable. We even encourage storing all colour values within the settings. Don’t repeat yourself. Create a sub-structure, similar to /sites if the structure becomes more complex.

Warning

Do not add additional variables to /private/sass/settings/_bootstrap.scss. This file is reserved for Bootstrap-only variables. Use /private/sass/settings/_custom.scss instead.

## sites/¶

Besides /addons you will work mostly within the /private/sass/sites folder. All custom elements that are in general not plug-and-playable, fixed into the website somewhere or specific components, get thrown in here.

This will force you to devise and adhere to structure patterns. Here are some examples depending on the requirements for your project:

Note

Multisite Setup

Let’s assume you create one style guide sharing different marketing websites or applications - your structure might look something like:

sites/
├─ application/
│  ├─ _all.scss
│  ├─ _general.scss
│  └─ _wizard.scss
├─ marketing/
│  ├─ _all.scss
│  ├─ _layout.scss
├─ _application.scss (imports application/_all.scss)
└─ _marketing.scss (imports marketing/_all.scss)


Note

Theme Setup

If you are using different themes for the same markup, your structure might look something like:

sites/
├─ dark_theme/
│  ├─ _all.scss
