As someone who normally acts as a content editor, I often get the opposite issue. The developer has created a form or CMS section that’s too restrictive. While this is probably great from a designer and developer viewpoint, it can restrict speed of change where marketing may need to adjust layout or add elements as business needs change, or even for one-off campaigns.

The perfect answer is to have the developer make the changes, but for many people this is not always practical. They may be working on another project, or if it’s an outside developer there may be no budget left for change requests at that point.

This leads to content editors having to bodge things as best they can, leading to some strange and non-standard stuff being done to make it look right. such as jamming HTML into form fields.
