Usage Example in UXML

Fixed Size Height

Classes like h-4 set a fixed height for an element. For instance, h-4 sets the height to 16px.

<ui:VisualElement class="h-4">
    <!-- Element with a fixed height of 16px -->
</ui:VisualElement>

Proportional Height

Classes like h-1of2 set a proportional height for an element. For instance, h-1of2 sets the height to 50% of the parent container.

<ui:VisualElement class="h-1of2">
    <!-- Element with a height of 50% of the parent container -->
</ui:VisualElement>

Full Height

The h-full class sets the height of an element to 100% of the parent container.

<ui:VisualElement class="h-full">
    <!-- Element with a height of 100% of the parent container -->
</ui:VisualElement>

Customize

Modifier Variations

Modifier Variations

You can customize which modifier variations of the Height utility are generated, such as pseudo-classes (e.g., hover, focus) and custom modifiers.

By default, no modifier variations are defined for the Height utility.

By fine-tuning the utility variations, you maintain control over your stylesheet's size and complexity, ensuring that only necessary styles are included. To update these values:

  1. Open the Theme Config Asset: Find the asset within your Unity project.
  2. Navigate to the 'Utilities' Section: Locate the Height utility.
  3. Adjust Modifier Variations: Select which modifiers you want to be generated for the utility. Keep in mind that the order of the modifiers will affect the order and specificity of the generated USS classes.

Class Tags and Properties

Class Tags and Properties

The Height utility generates classes based on predefined tags and their associated USS properties. While we recommend keeping these defaults for consistency and ease of reference in our documentation, you have the option to customize them to suit your project's specific needs.

These values are prepended to the defined values in this format tag-{value}. If a tag is empty, the generated class will simply be the value by itself.

Here are the default tags and the USS properties they set for the Height utility:

  • h : height

To customize these tags and properties, you can edit the Tag Property Map field for the Height utility in the Theme Config asset. This allows you to define new tags or modify existing ones, thus tailoring the generated classes to your preferences.

Extending Core Fields

The Height utility uses values from the following fields from the Core section of the Theme Config asset:

  • Spacing
These fields are used in addition to any custom values defined for the utility. If the same key exists in both the utility and core configurations, the utility's values will override those from the core.

To customize or define these extended fields:

  1. Open the Theme Config Asset: Locate the asset within your Unity project.
  2. Navigate to the 'Utilities' Section: Find the Height utility.
  3. Customize Extend Fields: Modify or add fields in the Extend Fields array to change the core configuration values that are extended. You'll only be able to extend fields of the same type.

Disable Utility

The Height utility is enabled by default. You can disable it by unchecking the Enabled option in the Theme Config asset. This will prevent the generation of the utility's styles.
