Background color for a specific block

Is it possible and how can I change the background colour of a specific block displayed on a basic page?
Thank you in advance for your help.

Dear Catherine
You have several options for that.
1-> You can add HTML tags inside the block. Edit block, select ‘source’ add this at the bigining

and add this at the end
2- Adding a Field group in the manage display.(need more steps, if you need help just tell us)

best regards

Dear Guillermo,

Thank you for your answer. Could you please specify what HTML tags I have to put in the block ?
