I have this table that is simple but i am not able to add colors through css to it, at present i have used inline css will convert it to external css later. i wish to show the table head with different color and the rows of the table that contain data should be of 2 colors that run alternatively. Would appreciate if someone could help me

P.S some people wanted to see my other sheet, here it is

<style>
        table { border-collapse: collapse; font-family: Futura, Arial, sans-serif; border: 1px solid ; margin-left:180px; width:1000px; margin-top:30px;}
        caption { font-size: larger; margin: 1em auto; }
        th, td { padding: .65em; }
        th, thead { background-color: ffecc4; border: 1px solid ; }
        tr:nth-child(odd) { background: #ccc; }
        tr:hover { background: #aaa; } 
        td { border-right: 1px solid #777; }         
    </style>

In html TABLE you cannot give background-color or color to <thead>. <thead> doesn't not take any colors. You can do..

#miyazaki thead th{
 background-color:red;
 color:#000;}

And for alternate colors you can apply

#miyazaki tr:nth-child(odd){ 
    background: #b8d1f3;
}

#miyazaki tr:nth-child(even){
    background: #dae5f4;
}
