I believe that this is as simple as creating a file called HEADER.html
(make sure you use uppercase lettersi for the word "HEADER") and include
some <style> tags.

Yes. Find the option in your Apache configuration file called
"DirectoryIndex" and change it to include index.php. Here's an example:
DirectoryIndex index.html index.htm index.php
This will allow you to write your own version of a directory listing in
PHP. If you don't want to write your own directory listing script,
continue on below...

Here's what I came up with:
1. Create a file called "textfile.php". Put code in there that reads
the variable $_REQUEST['file'] and verifies that it doesn't
contain anything nasty. (Basically, verify that it only contains
the characters A-Z, a-z, 0-9, a dash, an underscore, no more than
one dot, and the extension ".txt".) Use that variable to open up a
text file.
2. Add a rewrite rule to the .htaccess file that looks something like
this:
RewriteEngine On
RewriteRule ^/textfiles/([^/]+\.txt)$ /textfile.php?file=$1 [PT]
(This presumes your text files are being hosted in the
subdirectory "/textfiles".)
3. In the file "textfile.php", use the function
"file_read_contents()" to read the contents of the text file.
And, of course, be extra careful when checking the file name so that
people cannot pass a parameter that looks like "file=../../../etc/passwd"
or something like that.
