On the Boost website, the image in documentation headers is full bleed (no white border). For example: http://www.boost.org/doc/libs/1_61_0/doc/html/boost_asio.html

How do I achieve this in my own documentation? I have set the image in the Jamfile, but I have no idea how to adjust the border: http://vinniefalco.github.io/beast/index.html

The Jamfile and supporting source files are here: https://github.com/vinniefalco/Beast/tree/master/doc

The header on the website is actually added by a php script, not by boostbook. I was going to suggest doing it in CSS, which is possible but the markup boostbook generates for the header is pretty bad and makes it difficult, so instead I think I'll implement an alternative header style that you can set. Maybe using something like 'nav.border=Fullbleed', or perhaps by adding an option to let you use your own css class and style it yourself? I'll try to get that done after the new release. I put up a quick attempt at: https://github.com/danieljames/boostbook/commits/feature/header-image-option... Although it won't work properly without extra CSS along the lines of: .header-fullbleed { margin: -1em -1em 0 -1em; overflow: hidden; } .header-fullbleed img { display: block; }
