IN R MARKDOWN, How Can I add a background image (HTML output)?

问题

I'm trying to put an image as background for my R markdown document (HTML output) Instead of the black background. I Was searching everywhere in the documentation on how to do this but I can't seem to find any answer as it's my first time working with R Markdown.

I can't seem to know how to put the background image and how to divide it that way so I can have my content in the middle

I'm also trying to attach a Hyperlink to tablist option,in the Picture2 as you can see "Source" as for when I click on it, it directs me to an external page but ## [Source] ("github.com/example") isn't working which was the syntax in the documentation.

this is my code till now .. I hope you can help me with these two questions, it's again : - How to set a background image to an HTML output on the whole page like the black background and how can I make the click on " Source " or TabItem directs me to an external link?

Thank you

1) Regarding background theme check this out: https://rpubs.com/thaufas/555157

2) Try [github](someurl) with no space in between. EDIT: Regarding opening the link in markdown there try these links R Markdown - Hyperlink outside Rmd file or Linking to url with rmarkdown using Knit Word in Rstudio.
