BuddyPress.org

Please if anybody can help me, i’ve managed to style most of my buddy press layout. but im stuck with two problems.

1. in the sub nav area of ‘personal’ for ‘activities’ you have the ‘show’ activity drop down box.
what css code can i use to style it. When i select it the drop down items are highlighted in blue and i need to change that color. i also have this problem for the members page, for the ‘last active’ drop down box.

2. i’ve styled my buddy press buttons but the members page button was left out. i used this css:

#buddypress .standard-form button,
#buddypress a.button,
#buddypress a.button,
#buddypress input[type=”submit”],
#buddypress input[type=”button”],
#buddypress input[type=”reset”],
#buddypress ul.button-nav li a,
#buddypress ul.button-nav li.current a,
#buddypress div.generic-button a,
#buddypress .comment-reply-link {
background: #000 !important;
font-family: Oswald, sans-serif, Times, serif;
border: 0;
color: #000;
outline: none;
text-decoration: none;
color: #fff;
}
#buddypress .standard-form button:hover,
#buddypress a.button:hover,
#buddypress a.button:focus,
#buddypress input[type=”submit”]:hover,
#buddypress input[type=”button”]:hover,
#buddypress input[type=”reset”]:hover,
#buddypress ul.button-nav li a:hover,
#buddypress ul.button-nav li.current a,
#buddypress div.generic-button a:hover,
#buddypress .comment-reply-link:hover {
font-family: Oswald, sans-serif, Times, serif;
background: #000 !important;
border: 0;
color: #000;
outline: none;
text-decoration: none;
color: #ffa200;
}
button:hover,
input[type=”button”]:hover,
input[type=”reset”]:hover,
input[type=”submit”]:hover {
opacity: 1.0;
}

What can i use to style the members button? if anyone can help me out. thanks in advance
