Is there a way to have links in subdirectories that don't end in:
"directory/file.html" when you input the <a href="file.html"></a> in them? Or do I have to type in the whole address in the code?

thx in advance

If all your files are in your subdirectory (including your index!), then you don't have to write /subdirectory/file.html because all you have to write is file.html. Remember: as long as your index is in that subdirectory as well!

you mean you want a link to move up a directory?

using <a href="/file.html">...</a> should work

The slash thing worked! :)
Thank you so much
