Hello, I’m aware about legal attributions and requirement of colorlib copyright credit link in free themes but I was curious if it is possible to slightly edit the copywrite element as example given in attached image?
Hi there
Hope you are having a good day and thank you for your question 
Unfortunately, I’m afraid as per the license terms, you will need to buy the license to be able to make any changes to the license attribution.
Thanks!
