In my efforts to brand a SharePoint installation with a number of unusual colours I found my self struggling with the comments text on the blog pages. Comments were always being displayed in a light grey which was hard to read against a slightly off white background. To make things worse when a user is creating a comment they have no control over font/colour. I ended up using the following CSS to force the comments to be displayed in a much darker colour.
H3.ms-CommentHeader {
POSITION: relative; PADDING-BOTTOM: 0px; MARGIN: 0px; PADDING-LEFT: 0px; PADDING-RIGHT: 0px; COLOR: #1e1e1e; FONT-SIZE: 1.6em; RIGHT: auto; FONT-WEIGHT: normal; PADDING-TOP: 0px; TOP: -0.25em; LEFT: -2px
}
H4.ms-CommentTitle {
PADDING-BOTTOM: 0px; LINE-HEIGHT: 1.7em; MARGIN: 0px; PADDING-LEFT: 0px; PADDING-RIGHT: 0px; COLOR: #1e1e1e; FONT-SIZE: 8pt; PADDING-TOP: 0px
}
.ms-CommentBody {
PADDING-BOTTOM: 12px; LINE-HEIGHT: 1.7em; WIDTH: 775px; COLOR: #1e1e1e; FONT-SIZE: 8pt; PADDING-TOP: 6px
