A question about a JavaScript(?) code.

You mean like this?:

<a href="#gohere">Go to gohere</a>
When<br>
you<br>
click<br>
the<br>
link<br>
above,<br>
it<br>
should<br>
skip<br>
past<br>
all<br>
this<br>
text<br>
to<br>
the<br>
line<br>
below.<br>
<a id="gohere"><b>You made it</b></a><br>
this<br>
text<br>
will<br>
add<br>
enough<br>
stuff<br>
below<br>
the<br>
new<br>
position<br>
so<br>
that<br>
your<br>
browser<br>
will<br>
shift<br>
its<br>
vertical<br>
position<br>
if<br>
you<br>
resize<br>
it<br>
very<br>
small<br>

Simple, isn't it?
