WordPress templates, available online, are in two versions:
As a rule, free templates are downloaded in thousands, and they can be found at many sites of similar blogs. If the template (also known as R & D) is in addition functional and very beautiful, the sites with a similar design are growing like mushrooms. The advantage of such templates is that they are very easy to install, and to change them based on your needs does not requires you to have extensive knowledge of layout and PHP, only the basics of HTML.
At the moment not everyone can afford to order a unique template for the blog site, because you have to pay: the cost of website design, layout, editing, and introduction of certain functions in the template. Therefore, it would be best, if you download the most suitable to your needs one of the best wordpress templates and install it on your blog.
