Define custom background image(s) for search result page?

Hi,

I’m using WordPress and the free Hestia theme for my tech blog hosted at https://blog.microlinux.fr. As you can see, I’ve stripped down most of the options and features and really only use it to display my articles.

All the articles display a carefully chosen background image that gives a first idea of the article’s topic. Example:

https://blog.microlinux.fr/squidanalyzer-rocky-linux-8/

But when the reader clicks on the search icon and searches for a term, the result page show the default pink background color. Example:

https://blog.microlinux.fr/?s=squid

The same thing happens when the reader clicks on a tag at the bottom of the article to view related articles. Example:

https://blog.microlinux.fr/tag/squid/

Is there a way to choose some sort of default background image for search result pages and/or tag pages to replace that default pink color? Or even better, is there some way to define this image corresponding to the used search term and/or tag? For example, display a “desktop” image for searches related to “desktop”, and a “server” image for searches and/or tags related to servers?

Cheers from the sunny South of France !
