Does the info below in bold mean I can stay in Denmark for 90 days in addition to the 90 days I spent in other areas of Schengen? So in total I can be in Denmark for 90 days and Spain for 90 days and it is ok?

Maximum stay periods

If you are travelling visa-free, you may stay in the Schengen region for a maximum of 90 days in any 180-day period. The 90 days can be used either for one long stay or several shorter stays. The Immigration Service recommends that you use a calendar to count days from the date of entry up to and including the date you leave the country. Note: Both the entry day and the exit day count towards the 90 days in any 180-day period – regardless of the time of day you enter or exit the country. It is always your own responsibility to be aware of how long you are allowed to stay in Denmark. Read more about maximum stay periods

Citizens of certain countries are entitled to stay in Denmark for 90 days, regardless of stays in other Schengen countries Citizens of Australia, Canada, Chile, Israel, Japan, Malaysia, New Zealand, Singapore, South Korea and the US can freely enter and stay in Denmark for up to 90 days in any 180-day period, regardless of whether they have stayed in another Schengen country prior to entry into Denmark. The 90 days are counted from the entry date into Denmark or another Nordic country. If you have previously spent time in Denmark or another Nordic country within the previous 180 days, that time will be deducted from the 90-day maximum.
