What is the best way to code an age gate in Webflow that stores a variable in sessionStorage and removes the overlay on click?

To code an age gate in Webflow that stores a variable in sessionStorage and removes the overlay on click, you can follow these steps:

1. Create an overlay element: Start by creating a div element that covers the entire screen and serves as the overlay for the age gate. Give it a unique class name, like "age-gate-overlay".

2. Style the overlay: Use Webflow's designer tool to apply your desired styles to the overlay, such as a translucent background and centered text.

3. Create the age gate form: Inside the overlay, add a form element with input fields for the user to enter their age. You can use text fields or select dropdowns depending on your design preference. Add a submit button as well.

4. Style the age gate form: Apply appropriate styling to the form elements within the overlay. You can modify the colors, fonts, and sizes to match your website's design.

5. Add interactions to the age gate overlay: In the interactions panel, add a new interaction to the overlay element. Set the trigger to "Page Load" and choose the "Hide" option. This will hide the overlay initially.

6. Add interactions to the age gate form: Create a second interaction for the form submit button. Choose the trigger as "Click" and set the target as the overlay element. Select the "Hide" option to hide the overlay when the form is submitted.

7. Code the JavaScript: To store the age input in sessionStorage, you need to add a custom code block. In the page settings, scroll down to the footer section and click on "Custom Code". Select "Add Custom Code" and choose "Before ". In the code block, write JavaScript code to store the age input in sessionStorage. For example:

$(document).ready(function() {  $('form').on('submit', function(e) {    e.preventDefault();    var age = $('#ageInput').val();    sessionStorage.setItem('age', age);    $('.age-gate-overlay').hide();  });});

Note: This code assumes you are using jQuery. Make sure to include the jQuery library in your project if you haven't already.

1. Test and customize: Preview your Webflow project to test the age gate functionality. Make any necessary adjustments to the styling or code to ensure everything works as intended.

By following these steps, you can create an age gate in Webflow that stores a variable in sessionStorage and removes the overlay on click. This way, users will only need to enter their age once per session.
