The Good Web Host

A clonable project created to help you save time when developing forms on Webflow, now with Form Validation!

With this project, you can copy-paste a custom code element with a <select>
tag with all the countries in the world!

You have three options: 
1. With Emoji Flags
2. Without Emoji Flags
3. Without the Nice Select

DISCLAIMER: the countries are loaded in with JS - so you wouldn't be able to see them on Webflow however when you publish - Voilà!

Memberstack

Happy Wednesday! I noticed people were looking for an easy way to confirm password fields in Webflow, so I decided to create this!

There are a few solutions available today, but they don't give much (or any) style control or user feedback while the user is typing. This project does both!

It uses some custom code from Stack Overflow + some custom CSS to style neighboring elements. Tutorial video in the project.

Works with Memberstack, but you're welcome to adapt to any project! I hope it serves you well 😁

Had some fun rebuilding Webflow's signup, login, and forgot password UI inside Webflow. Social login and account creation are powered by Memberstack.

Give your users a slightly better experience with this easy email validation - all you need to do is:

1. Copy one line of code from the page 
2. Add a blank attribute called "nw-email" to the input
3. Create combo classes for your input called "success" and "error"

And you're done!
