Style Inheritance

NOTE

The APIs of this module are supported since API version 9. Updates will be marked with a superscript to indicate their earliest API version.

A custom component has the inherit-class attribute, which is defined in the following table.

To enable a custom component to inherit the styles of its parent component, set the inherit-calss attribute for the custom component.

The example below is a code snippet in the HML file of the parent component that references a custom component named comp. This component uses the inherit-class attribute to inherit the styles of its parent component: parent-class1 and parent-class2.

<!-- xxx.hml -->
<element name='comp' src='../../common/component/comp.hml'></element>

<div class="container">
    <comp inherit-class="parent-class1 parent-class2" ></comp>
</div>

Code snippet in the CSS file of the parent component:

/* xxx.css */
.parent-class1 {
    background-color:red;
    border:2px;
}
.parent-class2 {
    background-color:green;
    border:2px;
}

Code snippet in the HML file of the custom component, where parent-class1 and parent-class2 are styles inherited from the parent component:

<!--comp.hml-->
<div class="item">
    <text class="parent-class1">Style 1 inherited from the parent component</text>
    <text class="parent-class2">Style 2 inherited from the parent component</text>
</div>
