Slider Checkout: Changing font color?

[Develio13]

Hello,

 

I recently just spent £50.00 on a new theme template for my site, but the developer is refusing to tell me how I can change the font color on the Slider Order Form, as "Payment Method" and "Promotion Code" are showing as white font, on a white background (I want the font to be black like the rest of the font on the page.)

 

The developer offered to do it for me, but wants £15.00 just to change two bit's of font color which is a rip-off considering I've already paid a fortune for it.

 

What can I do? I tried editing the Style.css with the following attempts:

 

#order-slider .checkoutcol1 {
   float: left;
   width: 49%;
.entry-header h2
{
 color: black;
}
}

#order-slider .checkoutcol2 {
   float: right;
   width: 49%;
.entry-header h2
{
 color: black;
}
}

 

#order-slider .checkoutcol1 {
   float: left;
   width: 49%;
   color: #000000;
}

#order-slider .checkoutcol2 {
   float: right;
   width: 49%;
   color: #000000;
}

 

#order-slider .checkoutcol1 {
   float: left;
   width: 49%;
   h2 { color: #000000 };
}

#order-slider .checkoutcol2 {
   float: right;
   width: 49%;
   h2 {color: #000000};
}

 

I checked the font type with Google Chrome Element Tools, when selecting the text it shows as h2 so I'm pretty sure that's right.

 

What else can I try or do? I'm loosing customers very quickly when they reach the last page with this problem.
