Third-party web publishing tools and services can help you with creating content for specific purposes, such as surveys. If these tools and services do their job well, the task of creating accessible content is made much easier. However, if they have accessibility limitations, then you need to know about them so that you can take steps to avoid or minimize accessibility barriers in the content you create using these services or tools.
In general, you should look for published accessibility advice relating to the service or tool and follow any advice it gives. The advice may be provided by the vendor, as part of the tool or service's help documentation, or as a Voluntary Product Accessibility Template. Or, there may be third-party reviews or tutorials that provide useful advice on how best to use the tool or service to create accessible online content.
