If you use BlogCFC, please edit your style sheets so that the code style adds "courier new" to the list of fonts and changes the size to 1em. For a while now I've been wondering why code blocks were small on BlogCFC sites, but only on my Mac. I want to thank Chris Jordan for sending me the fix and sharing it on the cfbloggers listserv.
Oops, forgot to paste the final code:
.code {
font-family: "courier new",courier,monospace;
font-size: 1em;
color: black;
border: solid thin #0000cc;
background-color: #ffffcc;
overflow: auto;
max-height: 200px;
padding: 4px 4px 4px 4px;
line-height: 15px;
margin:5px 0 5px 0;
}
