You may define css class in your css file. After defined your class, you may set your grid CssClass property with your class name. For ex.;

.GridStyle
{
    border: 6px solid rgb(217, 231, 255);
    background-color: White;
    font-family: arial;
    font-size: 12px;
    border-collapse: collapse;
    margin-bottom: 0px;
}
.GridStyle tr
{
    border: 1px solid rgb(217, 231, 255);
    color: Black;
    height: 25px;
}
/* Your grid header column style */
.GridStyle th
{
    background-color: rgb(217, 231, 255);
    border: none;
    text-align: left;
    font-weight: bold;
    font-size: 15px;
    padding: 4px;
    color:Black;
}
/* Your grid header link style */
.GridStyle tr th a,.GridStyle tr th a:visited
{
        color:Black;
}
.GridStyle tr th, .GridStyle tr td table tr td
{
    border: none;
}

.GridStyle td
{
    border-bottom: 1px solid rgb(217, 231, 255);
    padding: 2px;
}

You can apply styles and css classes to different elements of a GridView rather than just applying a css class to the main GridView.

<AlternatingRowStyle CssClass="style1" />
<RowStyle CssClass="style2" />
<HeaderStyle CssClass="style3" />
<FooterStyle CssClass="style4" />
<SelectedRowStyle CssClass="style5" />

If you look at the HTML which is generated for the GridView, you can then identify which elements are given the classes, then from this you can apply any styling you wish.

Mainly styling tr, th, td within the table.

You need to add this to CSS:

.grid-header a 
{ 
  color: White; 
  font-weight: bold;
}

and this to gridviews that are sortable: HeaderStyle CssClass="grid-header" to sort the blue on blue problem ...
