Type selectors

USS type selectors match elements based on their element types. USS type selectors are analogous to CSS type selectors that match HTML tags. For example, Button {...} in USS matches any Button elements in the same way that p {...} in CSS matches any paragraph (<p>) tag.

構文

The following is the syntax for a type selector:

TypeName {...}

When you write type selectors, specify only the concrete object type. Don’t include the namespace in the type name.

例えば、このセレクターは有効です。

Button { ... }

This selector is invalid:

UnityEngine.UIElements.Button { ... }

例

To demonstrate how simple selectors match elements, here is an example UI Document.

<UXML xmlns="UnityEngine.UIElements">
  <VisualElement name="container1">
    <VisualElement name="container2" class="yellow">
      <Button name="OK" class="yellow" text="OK" />
      <Button name="Cancel" text="Cancel" />
    </VisualElement>
  </VisualElement>
</UXML>

With no styles applied, the UI looks like the following:

The following type selector style rule matches the two Button elements:

Button {
  border-radius: 8px;
  width: 100px;
  }

The UI looks like the following when you apply the style:
