Colorway theme home page changes

I am trying to change some elements in the Colorway home page:
Label text size and colour
Link hover over from green to blue
Green colour blocks in footer to blue.
I looked at the page in Firebug and thought I found the code, copied it to Child Theme style.css file, changed colours and uploaded it.
No change. Here is the code, and any help would be appreciated in helping rectify this:

#menu li a {
	margin:0;
	padding-left:10px;
	padding-right:10px;
	padding-top:5px;
	padding-bottom:5px;
	position:relative;
	color: #0B3861;
	text-align:center;
	text-decoration:none;
    word-wrap:break-word;
}

a {
    text-decoration:none;
    color:#0B3861;
}
a:hover {
    color:#084B8A;
}

/*==========Menus Colors==========*/
#menu .ddsmoothmenu li li a.selected, #menu .ddsmoothmenu li li a:hover { /*CSS class that's dynamically added to the currently active menu items' LI A element*/
    color: #FFFFFF;
    background:#084B8A;
}
#menu li.current-menu-item a, #menu li.current-menu-parent a, #menu li.current_page_parent a, #menu li a.selected, #menu li a:hover,#menu li.current_page_item a  {
    color:#fff;
    background: url(../images/menu-bg.png) top repeat-x #084B8A;
}
#menu .ddsmoothmenu li li {
    background: #084B8A;
}

/*Top level menu link items style*/
/*#menu .ddsmoothmenu li li {
	background: #0489B1;
}
