If you're using native JavaScript, attach an event listener to the container holding the buttons and listen for click events. When a button is clicked, add a class, and with that class, you can style the button to be whatever you want.
const ratingContainer = document.getElementById("rating")
let prevTarget = null
ratingContainer.addEventListener("click", (e) =>{
const target = e.target.closest("button")
//ensure not the same button
if(target !== prevTarget) {
target.classList.add("highlight")
if(prevTarget) prevTarget.classList.remove("highlight")
prevTarget = target
}
}).highlight{
background-color: orange;
}<div id="rating">
<button id="1">button1</button>
<button id= "2">button2</button>
<button id= "3">button3</button>
<button id= "4">button4</button>
</div>
