Styled components: nested className selectors vs multiple styled components
0
In general, are there any significant performance differences between using one of these approaches over the other?
When using styled components I've noticed two common approaches:
- Have a styled parent component that uses className selectors to target child nodes for styling, and encapsulates those styles in the one place.
- Have multiple styled components for each individual node that requires styling, independent of any parent styled components.
1 - nested selectors
const MyComponent = styled.div`
display: inline-block;
position: relative;
.MyChildComponent {
position: absolute;
background: red;
}
.MySubComponent {
background: yellow;
}
`
// In use
<MyComponent>
<span className="MyChildComponent>A goose!</span>
<button className="MySubComponent">Click bait</button>
</MyComponent>
2 - discrete components
const MyComponent = styled.div`
display: inline-block;
position: relative;
`
const MyChildComponent = styled.span`
position: absolute;
background: red;
`
const MySubComponent = styled.button`
background: yellow;
`
// In use
<MyComponent>
<MyChildComponent>A Goose!<MyChildComponent>
<MySubComponent>Click bait</MySubComponent>
<MyComponent>
Obviously there are situational reasons to mix and match these approaches, and I'm not taking into consideration use cases where a component may be re-used throughout a code base. I'm instead asking in the context of large chunks of markup that are unlikely to change or be shared.

In my experience, inverting the mapping ofstyles -> elementstoelements (components) -> stylesis invaluable when trying to reason about why certain styles are applying. In less complex situations this may not be so noticeable, but I still make it a point to avoid selectors
