How to stop it floating at the footer?

Check your html source code:
For example your footer container looks like this:
<footer id="my-footer" class="my-long-footer">...</footer>
In this case Stop ID is my-footer.
If there is no id attribute at all, you have to add it manually in footer.php

Thank you, it worked like a charm!

I checked my html source code (editor). No <footer id”?????????”
You said I would have to add it manually in footer.php.

Not a coder. can you tell me where and how to add it?

You have to use theme editor (in Appearance section) not content editor!

I cannot desсribe you basic concepts of html, so editing footer.php is on your risk )

But do you really need this? You have pages with differtn fotter height?

A workaround alternative to editing the footer.php (for non-coders), may be to try adding a div to the top of your text FIRST footer widget.

Example: <div id="top-of-footer"></div>

Obviously, not a best practice, and if your first footer widget doesn’t contain a text widget, you’re out of luck.

Works for us until we finalize the footer code. Hope that helps.
