Currently, Docusaurus does not natively support text highlighting using double equal signs (==text==), which is a common syntax in various Markdown flavors and documentation tools. Adding support for ==text== to highlight text would improve readability and enhance content emphasis without requiring additional HTML or custom plugins. Expected Behavior: Text wrapped with == (e.g., ==highlighted text==) should render with a background color (similar to <mark> in HTML). This feature should work consistently across Docusaurus documentation and blog pages. https://www.markdownguide.org/extended-syntax/#highlight Use Case: This syntax is widely used in documentation and note-taking tools like Obsidian and Typora. Adding it to Docusaurus would make it easier for users to maintain a consistent writing experience across platforms. Would love to see this feature integrated! 🚀
