This is my code
import { Grid, Segment } from "@fluentui/react-northstar";
Usage:
<Grid columns="repeat(4, 1fr)" rows="50px 150px">
<Segment
color="brand"
content="Header"
inverted
styles={{
gridColumn: 'span 4',
}}
/>
<Segment
color="green"
content="Menu"
inverted
styles={{
gridColumn: 'span 1',
}}
/>
<Segment
content="Content"
styles={{
gridColumn: 'span 3',
}}
/>
</Grid>
The horizontal lines appear around each segments and around the Grid. The inline style using border:'none' or anything relater is also not working.
It's the default box-shadow CSS value currently set to
box-shadow: rgb(34 36 38 / 15%) 0px 1px 1px 1px;
Add this to your style class
boxShadow: 'none'
