# Code Highlight Html — REST API endpoint `code-highlight-html`

Returns syntax-highlighted HTML for a code snippet: HTML-escaped text wrapped in <span style="color: ..."> elements using one of six colour themes (dracula, monokai, github, nord, one-dark, solarized). This is the pure highlighting step of the Code Screenshot Generator page; it returns markup plus the theme background and foreground colours, not an image.
