@SandraH Looks like a custom end of survey to me. You should be able to align the content centrally (same as the text) within the editor of the end of survey message… If you do not see the option, you need to click „More…“ in the editor.

@SandraH Sorry, ignore my last comment. Forgot it was from the header. Probably the logo is defined in your theme. You can set the alignment to „Centered“ in the theme > logo configuration. See 16 here:

I figured it out! @chackbusch you pointed me down a good path. I ended up pasting this in the header

@SandraH , thanks for confirming your solution!
