assistant: Here's an example of how you could create a sign up form using HTML, CSS, and JavaScript with form validation:

```html

assistant: Here is an example of a simple sign up form using HTML, CSS, and JavaScript with form validation:

HTML:

'''php
<form id="signup-form">
  <div>
    <label for="first-name">First Name:</label>
    <input type="text" id="first-name" name="first-name" required>

  <div>
    <label for="phone">Phone Number:</label>
    <input type="tel" id="phone" name="phone" required>

    <input type="password" id="password" name="password" required>
  </div>
  <div>
    <label for="password-confirm">Confirm Password:</label>
    <input type="password" id="password-confirm" name="password-confirm" required>
  </div>
  <button type="submit">Sign Up</button>
</form>
'''

CSS:
'''css
#signup-form {
  padding: 20px;
  background-color: #f2f2f2;
  width: 500px;
  margin: auto;
}

#signup-form label {
  display: block;
  margin-bottom: 10px;
  font-weight: bold;
}

#signup-form input[type="text"],
#signup-form input[type="email"],
#signup-form input[type="tel"],
#signup-form input[type="password"] {

  padding: 10px;
  margin-bottom: 20px;
  box-sizing: border-box;
  border: 1px solid #ccc;
  border-radius: 5px;

  border: none;
  border-radius: 5px;
  cursor: pointer;

#signup-form button[type="submit"]:hover {
  background-color: #3e8e41;

JavaScript:

'''javascript
const form = document.querySelector("#signup-form");
const passwordInput = document.querySelector("#password");
const passwordConfirmInput = document.querySelector("#password-confirm");

form.addEventListener("submit", (event) => {
  event.preventDefault();

  if (passwordInput.value !== passwordConfirmInput.value) {
    alert("Password and password confirmation do not match.");
    return;
  }

  alert("Form submitted successfully!");
});

prompter: How do I get the HTML to use the CSS and JavaScript? I copied the HTML into a file called "signup.html", copied the CSS into a file called "signup.css", and copied the JavaScript into a file called "signup.js". I put all of those files in the same directory and opened the "signup.html" file in my browser. However, it doesn't appear to be using any of the styles defined in the CSS and the alert messages in the JavaScript never appear when I hit the "Sign Up" button.

Also, how would I deploy this in a way that allows me to record what users enter?
