-## Common Problems
-
-### Union types are not inferred without explicit annotation
-
-Style objects defined outside of `css` function and `sx` prop need explicit
-annotation to prevent following error.
-
-```tsx
-/** @jsxImportSource theme-ui */
-
-const style = { whiteSpace: 'pre-line' }
-
-// Type '{ whiteSpace: string; }' is not assignable to type 'ThemeUICSSObject'.
-// Type 'string' is not assignable to type '"inherit" | "initial" | "revert" | "unset" | "normal" | "break-spaces"
-return <div sx={style} />
-```
-
-_[Try it on CodeSandbox.](https://codesandbox.io/s/theme-ui-inferrence-too-wide-vkrf5?file=/src/index.tsx&view=editor&previewwindow=tests)_
-
-TypeScript assumes that `whiteSpace` here is a `string`, but the `whiteSpace`
-property in `ThemeUICSSObject` is a union of possible white-space values
-([see on MDN](https://developer.mozilla.org/en-US/docs/Web/CSS/white-space#Values))
-or a nested style object.
-
-We can explicitly annotate `style` ensure that it is a correct Theme UI style
-object and that `whiteSpace` is one of appropriate values.
-
-```tsx
-/** @jsxImportSource theme-ui */
-import { ThemeUICSSObject } from 'theme-ui'
-
-const style: ThemeUICSSObject = { whiteSpace: 'pre-line' }
-
-// No error
-return <div sx={style} />
-```
-
-_[Try it on CodeSandbox.](https://codesandbox.io/s/theme-ui-inferrence-too-wide-vkrf5?file=/src/index.tsx&view=editor&previewwindow=tests)_
-
-We could also fix our problem by narrowing the type of `style` with a
-[const assertion](https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-4.html#const-assertions).
-
-```tsx
-const style = { whiteSpace: 'pre-line' } as const
-```
-
-This is succinct, but error prone, because we won't get TS intellisense support inside of this object.
