Using html template from colorlib to create Wordpress theme.

So am a junior Wordpress developer with little project under my belt. However, i was wondering if it’s a good idea to use some of the free html templates on website like colorlib and the likes and create a theme with it to show what I can do and the likes but would I need a license from the template owner to do that? and can I give those themes out for free crediting the html template owner and passing a link back to there website or social media page. Not sure if it’s good idea as am trying to avoid Copyright infringement issues and the likes. Kindly advise if you done something like this before.

Hi John

Well, yes it’s up to you if you want you can use any of our templates for your project, if you want it free you have to keep footer credits in the place, otherwise you have to obtain a license, Licence - Colorlib
