Formating ALERT

[mickeymouse]

See my alert message in my code below. 

Thank you.

function getnxt()
{alert('For this message / alert box, is there a way of 1-Setting the font size, color and alignment (e.g., center)?  2-Eliminating the resulting top heading (name of website) or replacing it?  3-Starting a new line?');
return false;}

You can start a new line by putting "\n" in the string.

There's no other way to format the alert() box. What web developers do is create an HTML element which looks like a box and use Javascript to make it appear. Here's a simple example:

<style>
#alert-box {
  background: #FFF;
  border-radius: 12px;
  padding: 12px;
  box-shadow: 6px 6px 12px rgba(0, 0, 0, 40%);
  width: 480px;
  max-width: 95%;
  position: fixed;
  top: 40px;
  left: 50%;
  border: 1px solid #EEE;
  transform: translateX(-50%);
}
#alert-box .buttons {
  text-align: right;
}
#alert-box button {
  appearance: none;
  display: inline-block;
  padding: 8px;
  background: #0078d4;
  color: #FFF;
  text-align: center;
  min-width: 80px;
  border-radius: 6px;
  border-width: 0;
}
#alert-box button:hover {
  background: #3fa8f8;
}
</style>

<button id="show-alert"> Show alert </button>

<div id="alert-box">
  <div class="text">
    <p>For this message / alert box, is there a way of</p>
    <ol>
      <li>Setting the font size, color and alignment (e.g., center)?</li>
      <li>Eliminating the resulting top heading (name of website) or replacing it?</li>
      <li>Starting a new line?</li>
    </ol>
  </div>
  <div class="buttons">
    <button id="close-alert">OK</button>
  </div>
</div>

<script>
let box = document.getElementById("alert-box");
box.style.display = "none";
let closeButton = box.querySelector("button");
closeButton.addEventListener("click", e => { box.style.display = "none"; });

let showButton = document.getElementById("show-alert");
showButton.addEventListener("click", showAlert);

function showAlert() {
  box.style.display = "";
}
</script>
