How to access specific index in array and change its background?

Im making a pagination in react my problem is that when the page loads it should set color to 1st element in array indicating page 1 and also if i click the 1st or last button is should highlight the 1st or last page.Css focus works only if i click the page number.

<button>First Item</button>  <div>{pages number}</div> // 1,2,3,4,5,6,7,8,9  <button>Last Item</button>    .btnpage{  background-color:green;  }    .btnpage:focus {        background-color: red;        color: white;      }
