I’m new to envato market and want’s to upload products.
Need Help about Is it legal or not to use a free html template in my php products ?
It depends on the context, the degree of integration or editing to the original, what you want to do with the file and most of all the license associated with the templates.
Also if you intend to use any other open source file, just leave the credits from authors!
While you are promoting your work, you are also promoting their work too!
Fair enough for everyone
