Dark Style Icon/Frameset Issue

[RobDog888]

<font color="darkgreen">Where can I find the "fieldset CSS as well as the CSS contained within the editor_css template."?

The fieldset css here?

/* ***** define margin and font-size for elements inside panels ***** */
.fieldset { margin-bottom: 6px; }
.fieldset, .fieldset td, .fieldset p, .fieldset li { font-size: 11px; }

And the editor css template?
.vBulletin_editor {
background: {$istyles[pi_button_normal][0]};
padding: $stylevar[cellpadding]px;
}</font>
