Tip for visualising page layout

[Jim Higson]

Firefox's web dev toolbar already does something like this, but try adding
this to the top of your css:

*{border:1px solid red;}
* *{border:1px solid blue;}
* * *{border:1px solid green;}
* * * *{border:1px solid black;}
* * * * *{border:1px solid red;}
* * * * * *{border:1px solid blue;}
* * * * * * *{border:1px solid green;}
* * * * * * * *{border:1px solid black;}
* * * * * * * * *{border:1px solid red;}
* * * * * * * * * *{border:1px solid blue;}
* * * * * * * * * * *{border:1px solid green;}
* * * * * * * * * * * *{border:1px solid black;}
* * * * * * * * * * * * *{border:1px solid red;}
* * * * * * * * * * * * * *{border:1px solid blue;}
* * * * * * * * * * * * * * *{border:1px solid green;}
* * * * * * * * * * * * * * * *{border:1px solid black;}
*{ padding:2px }
