4. Finally, paste the JavaScript code of your web form in the Custom HTML Code box and hit Save.
You’ll notice that the web form is displayed on your web page, although its canvas might not expand to its original size, but that does not mean the same will appear for your page visitors. Hit Preview in the Editor Panel and you’ll see the web form is smoothly displayed, as in the example below.
From now on, your page visitors can submit the web form directly from your Strikingly webpage. Don’t forget to save changes to your webpage before leaving, of course. All form data will be sent to your 123FormBuilder account, in the Submissions section of your web form.
