It all has to do with the way the text size and font are defined for the forum's individual features. For instance, the text that appears in posts is defined as follows:
/* By default (td, body..) use Tahoma in white. */
body, td
{
color: #ffffff;
font-size: small;
font-family: Tahoma, arial, helvetica, serif;
}Whereas, the quote and code boxes are defined like this:
/* A quote, perhaps from another post. */
.quote
{
color: #000000;
background-color: #84add6;
border: 1px solid #182d42;
margin: 1px;
padding: 1px;
font-size: x-small;
}
/* A code block - maybe even PHP . */
.code
{
color: #000000;
background-color: #e7e7e7;
border: 1px solid #000000;
padding: 1px;
font-family: "courier new", helvetica, "times new roman", serif;
font-size: x-small;
width: 99%;
margin: 1px auto 1px auto;
white-space: nowrap;
overflow: auto;
}(x-small stands for extra small.)
I then clicked quote to Midnite's reply (same board), but there's nothing denoting the size.
You can't see those definitions because they're stored in a part of the forum that isn't visible/accessible to you.
