# New and improved Code Block macro for Confluence Cloud The Better Code Block macro is a drop in replacement for the default Confluence Code Block macro. It has all of the same features plus some more. ## Better syntax highlighting The default code block macro supports a meager 19 languages, whereas the Better Code Macro supports 149 unique languages! It contains support for all of the common languages that you might expect plus other more niche languages too. ## Better theme support The default code block macro supports only 8 themes, wheras the Better Code Macro supports 71 unique themes. Even beter than that, the Better Code Macro does not suffer from [a bug in the default code block macro][1] that prevents you from using more than one theme on a page. ## Copy to clipboard support There is rudimentary copy to clipboard support in the default code block macro but most users don't even know that it exists. The Better Code Macro elevates copy to clipboard support to first class support; enabling a simple button press to copy the entire paste to your clipboard. ## Almost total backwards compatibility The Better Code Macro is nearly fully compatible with the default code block macro. The only feature that the Better Code Macro does not support is 'line numbers'; and that was a deliberate choice. If you need line number support then you should use a Bitbucket snippert or a Github gist. [1]: https://jira.atlassian.com/browse/CONF-28582
