# The grid settings

Abstract

The SXA grid definition, its settings, and classes.

A grid system is a library of HTML/CSS components that let you structure a website easily. Grid systems help you create responsive websites that have consistent designs and ensure cross-browser support. Understanding how the SXA grid layout works provides you with an insight into how to use and change grid settings, and how to add classes.

By default, SXA comes with the following grid systems:

• Bootstrap 3 – responsive, mobile-first grid system with a 12-column layout that includes predefined classes. Default devices are:

• Phones

• Tablets

• Desktops

• Large desktops

• Bootstrap 4 - responsive, mobile-first grid system with a 12-column layout that includes predefined classes. Default devices are:

• Compact phones

• Phones

• Tablets

• Laptops

• Desktops

• Foundation – responsive, mobile-first grid system with 12-column flexible grid that can scale out to an arbitrary size. Default sizes are:

• Small

• Medium

• Large

• Grid 960 – 12-column grid, based on a width of 960 pixels. Default settings are:

• Size

• Prefix

• Suffix

### Note

All grid systems have different system rules, classes, and options. For more detailed information, refer to the different grid systems own documentation.

You can select a grid system when you create a site.

### Note

If you do not select a grid during the site creation process, by default the Bootstrap grid is applied.

In the site Settings folder (Sitecore/Content/Tenant/Site/Settings), in the Grid section, in the Grid Mapping field, you can map devices to a specific grid system.

### Note

For every new device that you add, you must configure the grid mapping manually. You must select the same grid system that you selected for the site in the Site creation wizard.

For example, you can use the Grid 960 system for mobile devices:

### Note

It is important to be aware that changing the grid system after you create your site requires many manual changes. Because of the references on your pages to the previous grid system, making a change to the grid system will break your layout.

Grid systems are stored as a feature in Sitecore (sitecore/System/Settings/Feature/) and include:

• The Grid Definition item – includes all grid system specific items (the devices and their classes).

• The Grid Setup item – the scaffolding item to include the grid in the drop-down list of the Create a new Experience Accelerator site wizard.

The Grid Definition item includes all grid system specific items that a content editor can use in the Experience Editor.

The following fields are included in the Grid Definition item:

Field

Rendering parameters field type

Grid Definition

Refers to the Grid Definition item. For example, for the Foundation grid system: Settings/Feature/Experience Accelerator/Foundation/Foundation

You can change the default layout settings of the renderings in the grid definition item of the grid system. For example, for the Foundation grid (sitecore/System/Settings/Feature/Experience Accelerator/Foundation):

The classes defined in the Grid Definition item correspond to the grid system details in the Media Library. For example, in the Experience Editor, you have the option to hide a rendering for visitors using a large desktop.

This option is set in the Visibility settings of the Bootstrap grid system (sitecore/System/Settings/Feature/Experience Accelerator/Bootstrap/Bootstrap/Large Desktops/Visibility/Hide only for large desktops):

This class is taken from the bootstrap.css file loaded in the Media Library (sitecore/Media Library/Feature/Experience Accelerator):
