# Display

How the platform is displayed to users — homepage layout, gravatar, menus, branding behaviour and similar visual preferences.

Access these settings under **Administration > Configuration settings > Display**. This category contains **24 settings**, listed below with the title and comment shipped in the platform's settings fixtures (`SettingsCurrentFixtures.php`).

> The variable name in code is shown in monospace. Use it when scripting via the API or when you need to change those settings at a global level by editing [`config/settings_override.yaml`](https://github.com/chamilo/chamilo-lms/wiki/Configurations#configsettings_overridesyaml).

## Settings

### `accessibility_font_resize`

### `gravatar_enabled`

**Gravatar user pictures**

Enable this option to search into the Gravatar repository for pictures of the current user, if the user hasn't defined a picture locally. This is great to auto-fill pictures on your site, in particular if your users are active internet users. Gravatar pictures can be configured easily, based on the e-mail address of a user, at <http://en.gravatar.com/>

*Default: `false`*

### `gravatar_type`

**Gravatar avatar type**

If the Gravatar option is enabled and the user doesn't have a picture configured on Gravatar, this option allows you to choose the type of avatar that Gravatar will generate for each user. Check <http://en.gravatar.com/site/implement/images#default-image> for avatar types examples.

*Default: `mm`*

### `hide_complete_name_in_whoisonline`

Some pages allow you to promote the portal or a course on social networks. Enable this setting to remove the links.

**Show admin toolbar**

Shows a global toolbar on top of the page to the designated user roles. This toolbar, very similar to Wordpress and Google's black toolbars, can really speed up complicated actions and improve the space you have available for the learning content, but it might be confusing for some users
