Hello, I see many web sites and many templates which propose a blog section (like theme forest for exemple).
I would to know if the blog system have to be implemented or if you can use a blog manager like wordpress that they embed in the web page.
I would to make a blog on my website but embed it in my template bought on theme forest
thank you very much.
Only the templates that you can find in the WordPress category are ready to be installed and used as they are with with a blogging platform (in this case WordPress).
There are many other HTML templates that only have styling for a blog, without actually implementing the backsystem. If you buy one of these, you will have to hire someone to transform it into a real WordPress template.
So, in short, if you want an easy solution, simply install WordPress on your site, buy a template only from the WordPress category here on TF and install it.
