A modal is a message box that is displayed on top of your screen. Modals put an overlay on the screen therefore, they take visual precedence over all the other elements.
To use the modal, you need to copy & paste the below code

<div class="rating flex-row">
<span class="rating-star">★</span>...
</div>

Note:You can use the class "filled" to fill a single star & "filled-siblings" to fill all preceding stars
