How it works
- Paste the code into an HTML or custom code block. WordPress, Squarespace, Wix and most site builders support this.
- The tools run in your reader's browser. Nothing they type is sent anywhere, and there are no ads or pop ups inside the embed.
- The tools resize to fit phones, tablets and laptops. Change the height number in the code if you want a taller or shorter box.
- Please keep the credit link under the tool. That is the only thing we ask in return.
- Want the box to grow and shrink with the tool so your readers never scroll inside it? Add the optional auto height code below once per page, under the embed code.
- Want a different tool or size? Get in touch through our contact page.
Optional auto height
If your site allows scripts, this small piece of code lets each WattFort tool set its own height. It only listens for messages from wattfort.com.
