The skin of a repository can be changed to any of the built-in skins using
the web interface by going to the /setup_skin web page (requires Admin
privileges) and clicking the appropriate button. Or, the --skin command

[fossil ui](../../../help?cmd=ui) or
[fossil server](../../../help?cmd=server) commands to force that particular
instance of Fossil to use the specified built-in skin.
Sharing Skins
-------------
The skin of a repository is not part of the versioned state and does not
"push" or "pull" like checked-in files. The skin is local to the
"push" or "pull" like checked-in files. The skin is local to the
repository. However, skins can be shared between repositories using
the [fossil config](../../../help?cmd=configuration) command.
The "fossil config push skin" command will send the local skin to a remote
repository and the "fossil config pull skin" command will import a skin
from a remote repository. The "fossil config export skin FILENAME"
will export the skin for a repository into a file FILENAME. This file
can then be imported into a different repository using the

The header.txt and footer.txt files of a scan are merely the HTML text
of the header and footer. Except, before being prepended and appended to
the content, the header and footer text are run through a
the content, the header and footer text are run through a
[TH1 interpreter](./th1.md) that might adjust the text as follows:
* All text within <th1>...</th1> is elided from the
output and that text is instead run as a TH1 script. That TH1
script has the opportunity to insert new text in place of itself,
or to inhibit or enable the output of subsequent text.
