e.g i purchase a template for my website and further i want to modify it for my own satisfaction and requirements ? that how much it could be modified ? At large extent ? or restricted ?
If you could use full sentences it may help us a bit more, I am finding it difficult to understand what you are trying to say.
Editting an entire website is NOT the same as editting a template, a template shall most likely come in the form of HTML and CSS only.
If you downloaded an entire website to use as a template, you would have a LOT of code that you don't need/won't be suitable for your own site.
Whether you download the site, or use a template you shall still need written permission from the owner.
