Colored Box Behind Title

[mberk]

Very simple question: how do you put a colored box around the title of a plotly plot (shown below)?

I see this is possible with annotations, but I did not see any documentation or examples with title text. Is this possible?

Thank you so much for the help!

Sorry this is not possible. You will have to use an annotation instead (use xref and yref as paper as described here https://plot.ly/python/text-and-annotations/#adding-annotations-with-xref-and-yref-as-paper).
