Thank you for doing this!

Because we like to minimize the styling effort, we want to align the document structure as close to Istanbul output as possible.

Istanbul renders the breadcrumbs inside the <h1> tag. Could you move the breadcrumbs inside it (without adding any special css classes. They seem like just <a> tags and texts)

Another minor suggestions:

• Let's use All files instead of Home
• Maybe let's not use <a> for the last part of the breadcrumbs as it points to its document itself.

The below is a screenshot of Istanbul output:

Thanks for the guidance, at the beginning, I thought about adding it to the title but didn't want to mess with existing staff.

I removed custom CSS and rewrote it as you suggested.

Sorry for the delay (I was sick a few days).

This looks very good! Thank you for your contribution!
