i tried this:
<style type="text/css">
blockquote {
font-size: 9pt;
border: 1px solid #c3c3c3;
background: #f6f6f6;
color: black;
margin: 0px 20px;
padding: 0px 10px
}
div.small {
background:#e5e5e5;
color: black;
margin-left:-10px;
padding:1px 2px
}
blockquote hr {
visibility:hidden;
height:1px
}
blockquote br {
font-size:1px
}
</style>
and it was the closest I could get to this actually working as shown on this board
(changed the second blockquote to div)
but it would then do the whole line in the different color
