January 1 and it all changes
When you visit a Schengen area country you will be using the non EU line in the past it was empty, now it will be full, your passport will be stamped on entry and exit.
So where the rules in the past have been lax, you can expect that they will be enforced, they need any money they can get with budgets as they are!!
There are 2 different things
Schengen area rules (Which as EU members did not apply to UK passport holders due to freedom of movement)
If you arrive in the area (not just Spain) on 1/1/21 and leave on 15/3/21 that is 74 days
In this example you can return on 16/6/21, 16 day before the end of a 180 period) and stay 90 days as the 1/1/21 falls off your stay calendar on 30/6/21 as that is day 181 and the 90 days are rolling along, but at the end of that you cannot return until 90 days have elapsed. I hope this explains the 180 day rolling calendar.
Remember time in Paris, Greece or in Germany (anywhere in the Schengen area excepting Ireland) in between and they count 7 nights = 8 days and reduce your time in Spain
So in the above example without any other trip to the area on the 13th of December you can return and stay for up to 90 days.
Separate from that are
Spanish residency Rules
After 90 days in Spain you should apply for residence, if you stay 183 day you are considered Tax resident, these rules have always applied but often been ignored by Spain and expats, with the Schengen area rules being applied UK passport holders can expect that this will change (not the rules but the ease of avoidance)
