Advanced Features

Custom Domains

duet.to supports custom domains like www.mysite.com to be used for duet.to sites. You may purchase a new domain name or use an existing one you already own. Just follow the below steps carefully.

Open your domain registrar admin interface and navigate to DNS management.
Create (or modify) a CNAME record with hostname www to domains.duet.to, this will point the domain to your duet.to site. If concerned about TTL you can set it to 3600. It might take up to one hour for this change to take effect depending on your ISP.
If your domain registrar supports domain forwarding, forward your main domain to the www hostname. For instance, if your domain is mysite.com forward it to www.mysite.com to make sure your main domain also works.
Visit your site a bit later and make it a beauty.

Include another HTML file

To avoid repeating content blocks like navigation menu and footer use the following duet.to tag to include HTML from another file like myfile.html for example.

{INCLUDE: myfile.html}

                            <input name="name" type="text" placeholder="Name" required>
                            

                            <input name="email" type="email" placeholder="Email" required>
                            

                            <textarea name="message" placeholder="Message" required></textarea>
                            

                            <button type="submit">Submit</button>
                            

                            </form>

Using Microsoft Excel

{EXCEL: mytable.xls}

Using Google Sheets

Create a Google Sheets document then select 'Publish to the web' from 'File' menu, click 'Publish' then copy the document key (the weird part only) and use the duet.to tag like blow.
