mobile version site mobile number always White color

Question

I created mobile version site for my Wordpress website. I created m.mysite.com. When I see m.mysite.com, mobile number showing what color(#000) I gave. But in mobile device, It's shows always White Color.

Code is,

<div class="header_number">
    281-407-6199
</div>

CSS is,

.header_number{
    background: url(images/bg_3.png);
    background-color:#919191;
    text-align: center;
    font-family:Verdana;
    font-size:26px;
    color:#813010 !important;
    padding-top: 4px;
    padding-bottom: 23px;
}
header_number a{
    color:#813010 !important;
}

I need to make it as same color in mobile device also. What to do?

Change

header_number a{

to

.header_number a{

You are missing DOT(.) in it.

Answer 2

Just update your style.

.header_number a{...}

Add DOT to class name.
