Skrifttype på editor script!

Hejsa!

Jeg har et script der giver mulighed for at lave html ændringer direkte på nettet! Jeg vil dog meget gerne have, at skrifttypen som standard er verdana i størrelse "1" kan dette tilføjes scriptet??

<script LANGUAGE="JavaScript">
function button_over(eButton)
    {
    eButton.style.backgroundColor = "#B5BDD6";
    eButton.style.borderColor = "darkblue darkblue darkblue darkblue";
    }
function button_out(eButton)
    {
    eButton.style.backgroundColor = "threedface";
    eButton.style.borderColor = "threedface";
    }
function button_down(eButton)
    {
    eButton.style.backgroundColor = "#8494B5";
    eButton.style.borderColor = "darkblue darkblue darkblue darkblue";
    }
function button_up(eButton)
    {
    eButton.style.backgroundColor = "#B5BDD6";
    eButton.style.borderColor = "darkblue darkblue darkblue darkblue";
    eButton = null;
    }
//~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
