XF 1.5 Bold text

[Ashley S]

Hello all
New to Xenforo style editing, just want to know if this is possible?

Red arrows = Keep the bolded text.
Black arrow = Remove bolded text.

I basically want to keep the last post as bold and same in the "New Posts" in the sidebar..
But I want to get rid of the "Members Online Now" bolded usernames and the board section name in the "New Posts" in the sidebar..

Basically when I remove this code - font-weight: bold; it removes everything that's bolded that has the arrows pointed to them.

.secondaryContent a
font-weight: bold;
color: #135694;
}

I just want last post bold and the last post in the new posts in the sidebar bold as well.
Is this possible? Thank you.
