Are you escaping backticks so you can display them within code blocks? If so, an easier way to do this is by having the outer-most pair of backticks use more backticks than the inner-most pair. It's easier to see than it is to explain in words...

To get this output:

```html
<p>Hello<p>
```

Use this markdown:

This is handled by docsify-tabs and will spare you from having to deal with escaping backticks.
