Changing color of an id with Javascript

I get all movie datas from Firebase and also i get score of the movies. If the score of the movie is higher than 70, then i will change color of the id as “deepskyblue”, if it is 50 or higher it will be “orange” and lastly if it is lower than 50 it will be “crimson”(red). When i do this, it only changes my first movie’s id’s color. But i wanna change all of them. How can i do this?

  var movieNo = 0;
let html = '';
var body = document.getElementById('editor');
var body2 = document.getElementById('week');

  var movies = `<div class="content"><img src="${img}" ><p><a href="Admin.html?movieId=${id}">${name}</a></p> <p> <i class="fa fa-star" id="star"></i>&nbsp;<a class="scoretxt">${score}</a> </p> </div>`;
