Registration form HTML
Let’s create a HTML file name it registration.html, here is were you will create the necessary code for the registration from and also will link it up with the conformRegistration.html file and the sign-in.html file.
Link up Bootstrap and Font Awesome
In the head you will once again add the links provided in the beginning of this tutorial for Bootstrap, witch we will use for basic styling and Font Awesome for icons.
The last link that we need is that for the style.css, witch you will add in the header tage but above the title tag. Now you are good to go and can stat

Conform Registration form HTML
Your next step will be to create the conformRegistration.html file. This will have the same setup in its head as did the registration.html file.
Once again you will need to link up the Bootstrap CDN, the Fontawesome CDN
This form, if successfully submitted will send the user to the welcome.html page.
In order to succesfuly submit this form we need to write a bit of javascript. If you wish you can create a separate file for this code but because this code will only affect the conformRegistration.html I will write the code in the this .html file and add it in a script tag before the closing body tag.

const input = document.querySelector("input");
const submitBtn = document.querySelector("button");
input.onchange = () => {
if (input.value !== "" && input.value.length === 5) {
submitBtn.disabled = false;
} else {
alert("Verification code need to be 5 numbers !");
submitBtn.disabled = true;
}
};
})();

Validating the registration
In order for this form to be validated we it only hase to pass to conditions.
- The input may not be empty
- The input length must be strictly equal to 5 digits
- Because we set the type of our input to numbers we will only be able to enter numbers and no string or symbols.

Registration & Conform Registration form JavaScript
Now let’s create a validation.js file. Here we will type out the javascript code that will take care of validating each form
Do not forget to link up the javascript file “validation.js” in your HTML file.
The first part of the javascript will validate the form and the second part will take care of animation of the fontawesom icons, each associated to a surten input filed in all of our forms.
(function () {
"use strict";
// Fetch all the forms we want to apply custom Bootstrap validation styles to
var forms = document.querySelectorAll(".needs-validation");
// Loop over them and prevent submission
Array.prototype.slice.call(forms).forEach(function (form) {
form.addEventListener(
"submit",
function (event) {
if (!form.checkValidity()) {
event.preventDefault();
event.stopPropagation();
}
form.classList.add("was-validated");
},
false
);
});
})();
// Focus Icons
const inputs = document.querySelectorAll("input");
console.log(typeof inputs);
Object.keys(inputs).map((key, input) => onBlurOnFocus(inputs[key]));
function onBlurOnFocus(input) {
input.onfocus = (e) => {
e.target.previousElementSibling.classList.toggle("text-primary");
};
input.onblur = (e) => {
e.target.previousElementSibling.classList.toggle("text-primary");
};
}
