get Firefox and install the developer add-on for Firefox – thet is a great help in identifying the styles of page elements, and you can try changes in the style css ‘in real time’.
try changing the width in ‘#sidebar-right’ to match the one of ‘#sidebar’, and adding new styles for the list elements:
#sidebar-right {
font: 1.3em Arial, Helvetica, sans-serif;
width:275px;
padding:10px 10px 10px 10px;
float:right;
background:#fff;
}
#sidebar-right ul {margin-left:5px;}
#sidebar-right li {margin-bottom:5px;}
change the numbers (5px) to get the result you like 😉
Thanks for the help!
Can you be more specific about the plug-in? Is it called WordPress Helper?
that plug-in has nothing to do with wordpress in general, it is just a tool for Firefox to make improving websites easier:
