In this web development tutorial, we will be creating a login and sign up form with HTML, CSS, and JavaScript. This form will allow users to sign in and create an account on our website.
We will start by creating the HTML for our form. We will need a form element, input elements for username and password, a submit button, and a div to contain our form.
We will then style our form with CSS. We will give our form a width of 500 pixels and a height of 300 pixels. We will also give our input elements a width of 100 pixels and a height of 25 pixels. We will style our submit button to look like a button and we will give it a width of 100 pixels and a height of 25 pixels.
form {
width: 500px;
height: 300px;
}
input {
width: 100px;
height: 25px;
}
button {
width: 100px;
height: 25px;
}
Now that our form is styled, we will add some JavaScript to it. We will first add a function to our form that will be called when the user clicks the submit button. This function will check to see if the username and password fields are empty. If they are, it will display an error message. If they are not empty, it will log the user in.
function login() {
if (username.value == “”) {
alert(“Please enter a username.”);
}
if (password.value == “”) {
alert(“Please enter a password.”);
}
else {
login();
}
}
We will also add a function to our form that will be called when the user clicks the sign up button. This function will create a new account for the user.
function signup() {
var username = document.getElementById(“username”).value;
var password = document.getElementById(“password”).value;
var email = document.getElement
