Thus, we have covered all of the existing CSS filters. Now is the perfect time to test your abilities with a challenge.
You need to understand what filters are applied to photos and assign the appropriate CSS values to the filters.
All filter values are integers. If it is allowed, they should be multiples of 5.
To completely invert the colors in the photo, set the filter invert to a value of 1 or 100%.
