Making a popup registration form
The button triggers the function showPopup(). This function will change the display status of the popupbox div to block. This makes the onload invisible div visible. This example is pure HTML CSS JS. No jQuery needed for this simple example. This example also only makes a onload invisible element, visible on button click. So you can probably fiddle around with this and manage to show/hide it and make a form on it for registration.

What Is a Popup Form?
A popup form is an overlay that appears on a web page to collect visitor information, typically an email address, phone number, or feedback. Unlike embedded inline forms that sit within the page content, popup forms display on top of the page and demand attention. They can trigger based on time delays, scroll depth, exit intent, or button clicks.

r/webdev on Reddit: Best method to create a popup login form?
March 28, 2023 -
Hey everyone, I'm creating my very first CRUD app! HTML, CSS, JS and Express with ejs.
I want to create a popup login/sign up form, similar to the one on Twitter, and I was wondering what the best way to go about this was:
Shall I write all the html, hide it and add an event to the button which toggles the class that makes the overlay and form appear? Or
Just write the container in html, and add an event to the button which fires a function that creates all the elements and appends them? (no inner html)
I was considering the second option, because this form is going to be in different places (home page CTA, show page and index page of someone isn't signed in, etc), so I was thinking that having a function build it out would be more functional (pun not intended) but I've been hearing that using js to create html should be kept to a bare minimum, so I'm curious to hear some more expert opinions.

I don’t know who said creating HTML in JS should be kept to minimum but I bet he is not the best JS guy. These days most of the web apps you see are 99% JS. The industry is moving towards integrating HTML and even CSS to JS… I would correct that to find a balance using JS if you want good performance, loading times and seo. If the guy concerned about performance he must be working on large scale apps… small to mid scale you should not face performance problems using frameworks. On the other hand if you use Classes, they cache the created HTML stuff in expense of some memory. But these days these are not so important that you use classes or go functional. Either way I would encourage you to follow MVC design pattern regardless if you use classes or functions and group them in an MVC like pattern. In short I would encourage you to go with your second option. But a container is not really needed. A popup is probably an absolute positioned container so you could just find and append to ‘body’ html tag in JS

Have you thought about using a CSS library? Many of them have recommended way make something like that.
