I’ve just found an HTML tag I never knew existed, and it’s something I’ve wished I had many times before!

The \<base href=""\> tag lets you set a default prefix to all links to external sources.

So for example:

```auto

<html>
    <head>
    <base href="http://www.kirupa.com">
    </head>

    <body>
    <a href="web/index.htm">PHP</a><br />
    <a href="forum">FORUM</a><br />
    </body>
</html>

```

The two links above would point to “[http://www.kirupa.com/web/index.htm](http://www.kirupa.com/web/index.htm)” and “[http://www.kirupa.com/forum](http://www.kirupa.com/forum)” respectively.

You can even set the base href as something like “[http://mydomain.com/folder/subFolder](http://mydomain.com/folder/subFolder)” and then traverse back up the directory tree using “…/” in your links.

I can see how this probably sounds very dull, but I think it’s brilliant, especially as I’ve never heard of it before.
