# Structure¶

Every folder within private/sass/ includes a file called _all.scss. This file is included within private/sass/base.scss which gets compiled into static/css/base.css. Update the all file to include additional modules, do not include files directly within base.scss.

The SCSS file is structured into 3 separate section for mobile, tablet and desktop. This allows for an easy responsive approach by maintaining the code within a single file.

Hint

The first line // @media all is commented in order to use the sass @extend functionality which is currently not available within @media rules.

Separate modules which are plug-n-play able and add them into this folder. Traditionally these are django addons which can be installed such as aldryn-blog, aldryn-news or aldryn-shop.

## layout/¶

Layout specific styles such as header, footer or general forms should be added here. Also specific definitions for print, retina or mobile only styles that are used globally should be defined here.

In addition you can set fonts, icons and custom mixins.

## libs/¶

As foundation, we use normalize.css as many other boilerplates are using in its default state.

We are using the foundation grid with 24 columns and a max-width of 960px which offers the most flexible way of designing and a readable code.

We include various helper classes inspired by bootstrap within private/sass/libs/_bootstrap.scss. It makes sense to read the code as most elements are setup using the settings within private/sass/settings/default.scss.

These files should generally not be overwritten.

## settings/¶

Control over color, sizes and other settings are found here. These settings have mostly impact on the available libraries. You can add additional settings file if required. For example private/sass/settings/_shop.scss.

## sites/¶

If you are working on a theme-based setup or have styles which do not fit into the folders described above, this is the appropriate place to add them.

This folder can be freely structured. _custom.scss can be used for quick fixes or hacks.

Hint

Deep Nesting It can often happen that you end up with large sites files like _marketing.scss and _application.scss. In order to modularise those files and create a better overview, you can create an additional folder and include all required files within the original scss files. This could end up with a structure as illustrated underneath.

sites/
├─ application/
│  ├─ _all.scss
│  ├─ _general.scss
│  └─ _wizard.scss
├─ marketing/
│  ├─ _all.scss
│  ├─ _layout.scss
