What’s a template?
A template is the skeleton of most wordpress websites. Its like the outline of any project where a builder is needed.
You can find many templates here among a sort of many other items available for sale.
Check out this link to Envato Marketplace, where you will find a bunch of different templates.
A template is not always ready to go and some expertise in the web world is required but youtube can show and support your decision to build if you have the many hours to build your own website.
Hope this helps
