Hey Sam,
Try adding this to your custom css box in Theme Options > Advanced Settings:
.entry-content {
background: rgba(255,255,255,.5);
padding: 20px;
}
.home .entry-content {
background:transparent !important;
}
You can change the color of your icon menu text with this css:
.home-iconmenu a h4, .home-iconmenu a p {
color: red;
}
Hope that helps!
