Relative
The Relative
component is a structural element designed to offset content or act as a bounding box for Absolute components. By applying offsets using the top
, left
, right
, and bottom
props, the Relative
component allows precise positioning of nested content relative to its original position.
Usage
The primary use case for the Relative
component is to offset nested content within the document structure or serve as a container for Absolute
components.
import Relative from '@components/Layout/Relative/Relative';import Block from '@components/Layout/Block/Block';
const App = () => { return ( <Relative top="50px" right="50px"> <Block>Content with top and right offset by 50px</Block> </Relative> );};
export default App;

Props
Prop Name | Type | Default | Description |
---|---|---|---|
style | JSX.CSSProperties | {} | Inline styles to apply directly to the component’s root element. |
class | string | "" | Additional CSS classes to apply to the component |
ref | BaseComponentRef | undefined | Retrieves the component’s DOM element and assigns it to a variable. The HTML element can be accessed using the element property of the returned ref object. |

Guide
Offsetting content
The Relative
component’s position is controlled by its position props ( top
, left
, right
, bottom
). Under the hood the component uses CSS position to offset the element. You can pass any valid CSS unit (e.g., px
, %
, vh
, em
) to these props to specify the directional offset of the component.
Example
import Relative from '@components/Layout/Relative/Relative';import Block from '@components/Layout/Block/Block';
const App = () => { return ( <Relative top="15vh" right="200px"> <Block>Content with top offset of 15vh and right offset by 50px</Block> </Relative> );};
export default App;
Important: Since the Relative
component uses position: relative
, the offset applied is purely visual. The component remains part of the document flow, meaning that any subsequent content will still be positioned as if the Relative
component occupies its original space.
If you need to remove content from the document flow entirely (e.g., for tooltips, modals, or overlays), consider using the Absolute Component, which positions elements relative to their closest positioned ancestor or the viewport.
Usage with the Absolute component
One of the main purposes of the Relative
component is to act as the bounding box for nested Absolute
components. When an Absolute
component is used within a Relative
component, its position is calculated relative to the Relative
component’s boundaries. This relationship ensures precise control over the placement of the Absolute
component without affecting other elements on the page.
Example
import Relative from '@components/Layout/Relative/Relative';import Absolute from '@components/Layout/Absolute/Absolute';import Block from '@components/Layout/Block/Block';
const App = () => { return ( <Relative style={{ width: '300px', height: '200px', border: '1px solid black' }}> <Block>Normally positioned content</Block> <Absolute top="20px" left="40px"> This content is positioned 20px from the top and 40px from the left of the Relative container. </Absolute> <Absolute bottom="0" right="0"> Positioned at the bottom right corner of the Relative container. </Absolute> </Relative> );};
export default App;
Accessing the HTML element
To access the HTML DOM element of the Relative
component.
- Declare a variable to hold the ref but don’t initialize it with a value
- The declared value should have a type of
BaseComponentRef
, which you need to import - Set the declared variable as the value of the
ref
prop of theRelative
component
Example
import { BaseComponentRef } from '@components/types/ComponentProps';import Relative from '@components/Layout/Relative/Relative';import Block from '@components/Layout/Block/Block';
let relativeRef!: BaseComponentRef
const App = () => { return ( <Relative ref={relativeRef} top="50px" right="50px"> <Block>Content with top and right offset by 50px</Block> </Relative> );};
export default App;
Now you can access the HTML element of relativeRef
with relativeRef.element
and make modifications to it if needed.
