Loader

The loader animation is useful to notify users of the background process that might take a few moments before showing the information they requested. The spinning loader has two variants, one for light background and another for a darker background.

UX/UI Guidelines

Check the design documentation of the component in ZeroHeight.

Implementations

The component Loader is available in the following technologies:

CSS Components

Web Components

Parameters

Parameters

Parameters are the attributes that can be used to customize the component when using it in a project. They apply to the WebComponents implementation and wrappers and to the Vue and React CSS implementations. Some parameters names change between the implementations, in order to follow the conventions of each technology and framework.

For example, the param model is named ngModel in Angular, modelValue in Vue, but stays as model in React.

By default, all the parameters are optional or can be set in different, except for the ones marked as required

The parametrization of the component can be done with the following custom params or properties:

Name	Type	Slottable	Description
content	string	✅	The text to be displayed in the loader.
small	boolean		Sets the loader as small
locale	string		The locale parameter is used to set the locale of the component. The value must be part of the registered locales in ZDS. If not set, the default locale of the document will be used. Have a look to the localization mechanisms.
custom	object		A record of key-value pairs to set the CSS custom tokens. It's a complex attribute set as an JS object in stringified JSON format. Example: <z-loader custom='{"fill":"#06e7a3"}' />
custom-str	string		The stringified version of the custom property. It follows the pattern key:value;key:value;, with the possibility of setting multiple values and spaces between the punctuation characters. Example: <z-loader custom-str="fill:#06e7a3" />
z-theme	string		Sets the theme of the component. The possible values are light and dark. <z-loader z-theme="dark" />
