yaferim - A site template is a set of files with a coded layout, logic and functionality, taking into account a specific content management system (CSM), which often includes additional components and extensions, as well as design files for changing the site.
The cost of creating a website based on a ready-made template is much cheaper than developing a website from scratch

xodor - I used templates to create a website. and I want to note that the use of a ready-made template significantly reduces the development time of the site, since in this case we skip two labor-intensive stages: design and coding (cutting the design and coding it in HTML + CSS + JS templates). You just need to install and configure the selected template, and then check the work of the Internet resource. I download wordpress themes here https://monsterone.com/wordpress/wordpress-themes/ and I got a great website that became a great online business platform
