Hi, everyone. Does anyone have examples of pretty pkgdown documentation websites for Bioc packages?
All of my Bioc packages have documentation websites that I create and automatically update thanks to the GHA workflow provided by {biocthis}. However, I think the default UI could be better.
I am looking for inspirational examples and suggestions (e.g., themes, fonts, etc). An example of a documentation website I find pretty is the pkgdown website: https://pkgdown.r-lib.org/

Code

Store those contents in pkgdown/extra.css, in the repository of an R/Bioconductor package on GitHub.

Small reproducible example

• Code: https://github.com/iSEE/iSEEhub
• Result: https://isee.github.io/iSEEhub/

R session information

Remember to include your full R session information.

options(width = 120)
sessioninfo::session_info()

The output of sessioninfo::session_info() includes relevant GitHub installation information and other details that are missed by sessionInfo().

Thanks for much for this! https://lcolladotor.github.io/biocthis now uses this ^^

I also added a function (biocthis::use_bioc_pkgdown_css()) to make it easier to add this css file and now mention it on the new package template.
