How we can create a multi-step form with progress bar using HTML, CSS, & JS? Solution: Multi Step Form With Progress Bar Using CSS JavaScript, Dynamic Form With Single Input.

Maybe you have seen multi step form on some websites or social network. This type of forms nowadays are on trend, most people using the form with multi-step. Multi step form creates a good user interaction on the webpage, the days are gone when people use the long form with many fields.

Today you will learn to create a dynamic multiple step form with the help of JavaScript. This form has just an input field that makes it unique, it also has progress bar & email validation. The whole UI is based on CSS & the functions are based on JavaScript. I take inspiration from dribble post to creating this.

So, Today I am sharing a Multi Step Form With Progress Bar Using CSS & JavaScript, A Single Input form with dynamic functions with help of JavaScript. There are some features which make this unique & better from others: This has a single input field, Email validation, Progress Bar, & a Welcome Massage.

Now you can see this visually. If you like this then get the source code of its.

CSS JavaScript Multi Step Form With Progress Bar Source Code

Before sharing source code, let’s talk a little bit about this. As you know the UI is created using CSS & functions are using JS. First, we have to create a div for the progress bar, then have to create a div for place input, label, button & Underline inside that.

In the JavaScript section, I created 4 variables for 4 separate form fields, JS fetch the div using its ID & changes the value of it. Inside the Email variable, I put a pattern for validation, & inside the password var put type password. There are many JS functions to handle various actions. For creating the progress bar, js changes the progress bar’s width by 25% on every action because there are 4 inputs.

I have used an Ionic icon for creating the next button after input. Using CSS I placed all elements in the right place, manage all colors & background colors. Actually JS fun the function & CSS changes the values. There are too many things, I can’t explain in writing. If you have knowledge of HTML, CSS & JS then you will definitely understand after getting the codes.

If you face any problem with understanding this, you can ask me in the comment section or contact form. Another option is you can directly message on our facebook page to get an instant reply.

For creating this program, you have to create 3 files. First for HTML, second for CSS, & third for JavaScript. Follow the steps to creating this without any error.

index.html

Create an HTML file named ‘index.html‘ and put these codes given here below.

<!DOCTYPE html>
