Code Block Macro - No Syntax Highlighting

[Rickey Whitworth]

When I use the Code Block Macro in Confluence Cloud (/code) I have the option to pick different languages. 

However, it doesn't matter what language I choose, I am not getting any kind of highlighting for the code. They all look the same, white text on a dark background.

Hi @Rickey Whitworth and welcome to the Community.

The code highlights will be visible once you save / publish the page. It's not displayed in the edit mode.

See the Python sample behavior

Hi @Rickey Whitworth ,

Just adding to @Kristian Klima 's answer — the native Code Block Macro does show syntax highlighting after publishing, but it has some limitations:

• No live preview while editing
• Limited theme options
• Basic language support

If you need more control, there's a newer app called Modern Code Blocks for Confluence that addresses these gaps:

• 85+ languages with proper syntax highlighting
• Monaco editor — the same editor VS Code uses
• Live preview — see how your code looks before saving
• Auto theme sync — matches Confluence's light/dark mode automatically
• Customization — line numbers, word wrap, font size, minimap

 It's especially useful for engineering teams sharing code snippets regularly.
