hey - I'd suggest looking at https://opensource.com/article/20/4/git-merge-conflict for how to resolve conflicts looks like you managed, nice!

just need to revert changes to doc/source/user_guide/style.ipynb, if you do something like
```
git fetch upstream
git checkout upstream/main -- doc/source/user_guide/style.ipynb
git commit -a -m 'revert changes to doc/source/user_guide/style.ipynb'
git push origin HEAD
```
it should work @MarcoGorelli 
I think I am done with the requested changes barring any changes. > Nice work, looks good to me pending green

@MarcoGorelli 
Does that mean I could close the pull request? The reason for my asking is that I am also seeing a lot of errors popping up in the checks that are being carried out. 
By the way, this would be my first open-source contribution, when completed. Thanks for the opportunity. > @MarcoGorelli Does that mean I could close the pull request? The reason for my asking is that I am also seeing a lot of errors popping up in the checks that are being carried out. 

when it's ready, we will merge it - but first, the errors need fixing up @MarcoGorelli  Sorry, I have been away for a while. I have re-run and I still see the errors. Looking through to see where I might have gone wrong.

no worries :) I've suggested a couple of fixes, the rest looks good! @MarcoGorelli All tests passed. I guess merging can now be done. yup, should be good, I'll just wait for a few more jobs to finish
