color drop cap

Hello,

Thank you for this great theme
In a page I use a class. I want to make sure that the text is white with a blue background etc.
That works perfectly, but when I look on a iPhone the tel.number has the same color as the drop caps in the rest of the site. How do I tell the class to set the color in this class to white?
#top .feature-background {
text-align: center;
background-color: #0879a9;
padding-top: 0px;
padding-left: 5px;margin-top:20px;
color: #ffffff;
min-height: 18px;
font-size: 15px;
}

Thanks in advance, Woutski
