### Why Advance Custom HTML?
Plain code dumps are hard to read and impossible to interact with. **Advance Custom
HTML** lets you display HTML, CSS, JavaScript, PHP, Python, and other code snippets
in WordPress posts, pages, or widgets with built-in syntax highlighting, a clean
code editor, and live preview support – so your readers see the code and the result
side by side.
The plugin includes a front-end code editor with a draggable preview panel, multiple
syntax themes, and customizable settings for formatting and appearance. It is ideal
for tutorials, technical articles, and documentation – a flexible, responsive way
to embed and present code with real-time results.

### [Does not work | Aggressive Email Collection](https://wordpress.org/support/topic/does-not-work-refuses-to-uninstall-collects-emails/)
[Shaan](https://profiles.wordpress.org/yafarhad/) June 2, 2026 3 replies
All those features are locked behind Pay buttons! It also tries to collect email
addresses for so-called security updates. Come on! We don’t look for security updates
from a custom code block plugin. Don’t make it appear like it’s for WordPress core
updates.
