FAQs
Why Don't You Provide a styled
API?
Long story short: it's unnecessary.
cva
encourages you to think of components as traditional CSS classes:
- Less JavaScript is better
- They're framework agnostic; truly reusable
- Polymorphism is free; just apply the class to your preferred HTML element
- Less opinionated; you're free to build components with
cva
however you'd like
Example: Polymorphic Components
There's no as
prop in cva
, because HTML is free:
-- // A familiar `styled` button as a link
-- <Button as="a" href="#" variant="primary">Button as a link</Button>
++ // A `cva` button as a link
++ <a href="#" class={button({variant: "primary"})}>Button as a link</a>
How Can I Create Responsive Variants like Stitches.js (opens in a new tab)?
You can't.
cva
doesn't know about how you choose to apply CSS clases, and it doesn't want to.
We recommend either:
- Showing/hiding elements with different variants, based on your preferred breakpoint.
Example: With Tailwind
export const Example = () => (
<>
<div className="hidden sm:inline-flex">
<button className={button({ intent: "primary" })}>Hidden until sm</button>
</div>
<div className="inline-flex sm:hidden">
<button className={button({ intent: "secondary" })}>
Hidden after sm
</button>
</div>
</>
);
-
Create a bespoke variant that changes based on the breakpoint.
e.g.
button({ intent: "primaryUntilMd" })
This is something I've been thinking about since the project's inception, and I've gone back and forth many times on the idea of building it. It's a large undertaking and brings all the complexity of supporting many different build tools and frameworks.
In my experience, "responsive variants" are typically rare, and hiding/showing different elements is usually good enough to get by.
To be frank, I'm probably not going to build/maintain a solution unless someone periodically gives me a thick wad of cash to do so, and even then I'd probably rather spend my free time living my life.
