styledCreate a function to create styled elements.
styled(tag, { type, manager });
tag: An element tag name, custom element constructor, or function returns a element instance.options
type: Style application type ('global', 'scoped', 'adopted' or 'inline').manager: Style manager, used to update DOM and application styles.updateStyleUpdates the style of an element created by styled.
If there are no functions in the template literals, calling updateStyle is a no-op.
It should be placed where the state is updated.
updateStyle(element);
mixinCombines multiple style definitions into a single component, enabling composable styles.
It is useful for creating reusable atomic styles.
mixin(styler0, ...stylers);
styler0: The first style definition.stylers: The rest of the style definitions.element: The element whose style needs to be updated which created by styled functionStyles applied globally.
const MyComponent = styled("div", {
type: "global",
})`
/* root styles */
&:hover {
/* hover styles */
}
`;
MyComponent();
<head>
<style>
[data-ps="11201b20"] {
/* root styles */
}
[data-ps="11201b20"]:hover {
/* hover styles */
}
</style>
</head>
<body>
<div data-ps="11201b20"></div>
</body>
Styles applied within a scope.
const MyComponent = styled("div", { type: "scoped" })`
/* root styles */
&:hover {
/* hover styles */
}
`;
MyComponent();
<div>
<style>
@scope {
:scope {
/* root styles */
}
:scope:hover {
/* hover styles */
}
}
</style>
</div>
Styles applied within a opened shadow root.
const MyComponent = styled("element-with-shadow-root", { type: "adopted" })`
/* host styles */
&:hover {
/* hover styles */
}
`;
MyComponent();
:host {
/* host styles */
}
:host(:hover) {
/* hover styles */
}
Styles applied directly as inline styles to the element.
const MyComponent = styled("div", { type: "inline" })`
/* inline styles */
`;
MyComponent();
<div style="/* inline styles */"></div>
