Free Lightweight PopUp Contact Form

View the Demo

There are plenty of possibilities of how to make a nice popup contact form on your website. In this tutorial, I’m going to show you a plugin-free solution using the same technology as the Divi Builder → Magnific Popup. In this tutorial, I’m using Caldera Forms but you can use other forms such as Gravity Forms, Formidable Forms, WP Forms, and others. I chose Caldera Forms (which I’m also using on my own website) because it’s free and pretty extensive in terms of functionality.

1. Download Caldera Forms

Download the free Caldera Forms in the WP repository and install & activate it.

2. Create a New Form

For simplicity reasons, I’m going to use a caldera template for the contact form. You can use your own.
I made a little adjustment (deleted the second HTML field) to the template to keep the form simple. Below is the layout of my form (again, you can use you own!).
You may want to adjust form settings as well (just as email recepient etc.).

3. Create a new page and build your layout

You may have already created your page. The important thing is to have a button on your page which we will use to display the PopUp.

4. Give your button open-popup-link class

Open your button’s settings, go to the Advanced tab and click on CSS ID & Classes. Give the button a class of open-popup-link.

5. Add the Button Link URL as #contact_form

Go to the Button Settings, click on Link and add the Button Link URL: #contact_form.

6. Paste the PopUp HTML, jQuery & CSS code

You can paste the following code to a code module below your button, to the Theme Options, or to your child theme. For simplicity reasons, I pasted everything to a code module bellow my button.
<div id="contact_form" class="contact_form mfp-hide"></div>
.contact_form {
     position: relative;
     background: #FFF;
     padding: 50px;
     width: auto;
     max-width: 700px;
     margin: 20px auto;
     border-radius: 7px;
jQuery( document ).ready(function() {  
  mainClass: 'mfp-with-zoom',
  midClick: true
Your code module will look like this:
Note: Don’t use <style></style> tags if you paste your CSS to Theme Options or child theme’s CSS! Use it only in case of a code module.

7. Paste Caldera Form Shortcode just before </div>

Go back to your Caldera Forms overview and grab your form’s ID (it’ll be shown after clicking on Get Shortcode). Paste this ID just inside the div you pasted to the code module in step Nr. 6.

8. Style your form with CSS (optional)

You may want to style your form with a bit of CSS (the code below may be different if you decided not to use Caldera Forms).
/*** Contact Form CSS ***/
.contact_form {color: rgba(2, 36, 87, .7); letter-spacing: 1px;}
.contact_form h2 {font-weight: 700; color: #022457; font-size: 35px;}
.contact_form .caldera-grid .form-control {border: 0; box-shadow: none; background: rgba(0,0,0,0.05); padding: 25px; border-radius: 5px; margin-bottom: 20px; color: #022457;}
.contact_form .mfp-close {background: rgba(0,0,0,.05)!important; opacity: 1; color: #F25CA2; border-radius: 50%; margin: 10px; transition: all .3s ease;}
.contact_form .caldera-grid .btn-default {background: #F25CA2; color: white; border: 0; width: 100%; height: 60px; border-radius: 50px; font-weight: 700; font-size: 18px; transition: all .3s ease;}
.contact_form .caldera-grid .btn-default:hover {background: rgba(0,0,0,.05); color: #F25CA2; transition: all .3s ease;}

Let me introduce myself...

My name is Richard and I created my first website early at high school. I love the world of web design as well as the amazing and supportive Divi Community. As for the services I offer, I mostly work with firms and take care of their online presence but I also work as a sub-contractor for other web design studios.
