Line numbers

Lines highlight
To highlight individual lines use highlightLines
prop with object containing
line numbers as keys and highlight options as values. Highlight options include
color from theme.colors
and label which replaces line number:
Copy button
To remove copy button set noCopy

Copy button labels can be changed with copyLabel
and copiedLabel

Native scrollbars
By default, Prism uses ScrollArea component to handle overflow content,
to replace it with native scrollbars set scrollAreaComponent="div"
:
<p>Long code that will force Prism to have a horizontal scrollbar, by default, scroll behavior is handled by ScrollArea component, but it can be changed to native browser scrollbars</p>
With tabs
To display multiple files use Prism.Tabs
component, it supports the same props as Tabs component:
Force dark/light theme
You can force dark/light color scheme by setting colorScheme
prop:
Custom themes
Use getPrismTheme
prop to change prism colors. You can use premade themes from prism-react-renderer
package or build your own using Mantine theme colors. getPrismTheme
prop accepts
a function with two arguments: first is Mantine theme object, second is color scheme (light
or dark
).
The function must return prism theme object:
