Enhancing the Appearance of Default HTML Validation Messages

Is it possible to style default validation message boxes using CSS?

While I know how to edit the default validation message text, I am curious if there is a way to specifically target the validation message boxes with CSS.

This question stems from my appreciation for the default validation and is purely for research purposes. I have tried looking for ways to target the validation message box using my browser console, but unfortunately, have not been successful.

For example, could I change the background color of the validation message to blue instead of white? Or adjust the font-size? Is there a CSS solution for this?

You are not restricted to styling the message directly, instead, you have the freedom to create your own custom "message" element.

Expanding on the provided example, by adding e.preventDefault(), you can prevent the default action of showing the validity message and implement your unique element to display the message.

This updated version showcases a more elaborate example derived from the initial one. Now, there exists a genuine message box that clears once you refocus on the form.

document.forms.form01.addEventListener("invalid", function(e){
  e.preventDefault();
  e.target.classList.add('invalid');
}, true);

document.forms.form01.addEventListener("focus", function(e){
  e.preventDefault();
  [...e.target.form.querySelectorAll('.invalid')]
    .forEach(elm => elm.classList.remove('invalid'));
}, true);

label {
  position: relative;
}

div.feedback {
  border: solid thin red;
  position: absolute;
  left: 10%;
  padding: .2em;
  background-image: linear-gradient(180deg, #fff, #ddd 40%, #ccc);
  display: none;
}

input.invalid~div.feedback {
  display: block;
}

input:invalid {
  border: thin solid red;
}

<form name="form01">
  <label>
    <span>Name</span>
    <input name="name" placeholder="Enter Your Name" type="text" required autocomplete="off">
    <div class="feedback">This needs to be a name</div>
  </label>
  <label>
    <span>Email</span>
    <input name="email" placeholder="Enter Your Email" type="email" required autocomplete="off">
    <div class="feedback">This needs to be an email</div>
  </label>
  <button>Submit</button>
</form>
