I'm working on a simple website that I can reach through ftp. There is a login page, what is written in .php. I don't know php at all. My problem is: 
In the homepage .html file, a link only points to a folder (not a .html file or something) on the ftp server like this:

```
<a href="login/">

```

And it goes to a page that has html(pictures):

There is no html file on ftp server in the "login" folder. But I have to edit that login page. But my mind in now blown :D I know its kinda newbie question. 

Thanks in advance!
