WARNING: Embedding via an iFrame directly is depreciated. Instead we've created an embed method that uses iFrames under the hood. Please check out this guide.
In some rare instances, a calculator doesn't look right when embedded on your website. In almost all cases these issues are caused by third-party libraries (e.g WordPress plugins) or issues related to your website's design (CSS or HTML issues).
The proper way of solving these issues, is by addressing them directly: fix the issues on the website. If you are unable able to solve these issues or if you are ok with some limitations, you can embed a calculator via an iFrame.
