BuddyPress.org

Hi there… I have recently purchased the theme “Dynamix”.
I like the theme very much! But after a long search on the internet without success and taste so much, I am helpless. I just want to change the BuddyPress button color. Some of the buttons have no link. Just a note (like “member since…”). I tried it like this:
– Design
– Theme Options
– Customize

There, I typed in “Custom CSS”:

.button a: {
background-color: # 172a39;
border-color: # 0f1c26;
}
.button a: hover {
background-color: # 172a39;
border-color: # 0f1c26;
}

Unfortunately, nothing has changed. What should I do?
Is there anyone who can help me? I have not so much experience with css and anything like this…
Thanks a lot!
