Users appreciate that this WordPress plugin extends the standard Gutenberg block with additional themes and is easy to use. It allows for syntax highlighting across multiple languages and provides a sleek, customizable, and lightweight solution compared to other bulky alternatives. The plugin’s ability to set default themes and code types is particularly liked. It integrates well with the native Gutenberg block and requires minimal setup. However, some users noted it lacks support for the Classic editor and certain features like a "copy to clipboard" button. Additionally, it introduces an invalid "lang" attribute, which can disrupt HTML validation and accessibility standards. Despite these issues, it’s generally seen as efficient and effective.
