Offline forms

To create an offline form you must complete several steps:

Create an HTML document that will contain the required fields.
Add CSS styles.
Use the “JavaScript method” to send data from the form.
Upload the created form to any hosting that supports the HTTPS protocol and add a link to the form in the administration interface.

We recommend creating an offline form using the codepen.io web application for simplicity and clarity.

Entry:
Create a customized offline form that contains Email or Phone and allows to write a message.

}, "*");

JavaScript code of our example

Upload a form to any hosting

In our case, click the Save button first, then export to .zip format (see instructions below).

We have a form prepared, now you need to upload the form to the Internet so we can refer to it from the administration interface. In our case, we will use the GitHub site. You can find more information here.

If you use a tool other than codepen.io, the form code will look like this:

The last step

You created an offline form using codepen.io. You have exported it to your computer. You have uploaded exported folders to the GitHub repository and then switched on the GitHub website. This brings you a link to our form, which you insert into the administration interface.
