## Devhub Content Issue

Some things aren't displayed correctly in the guidelines web page. The image below shows them:


1. :heavy*exclamation*mark: is shown instead of :heavy_exclamation_mark:
2. \`*per*page\`_ is shown instead of *`per_page`*

### Suggested solution

1. Escape the underscores (`:heavy\_excalamation\_mark:`)
2.
1. Do not use italics there and everywhere else, if the code formatting can be deemed sufficient
2. Italicize using asterisks (``*`per_page`*``)
