There are a few completely free WordPress themes, but they are not very popular. Most WordPress users choose to buy a theme from one of the many popular theme stores.
However, there are a few free themes that are worth checking out.
One of the best free themes is called Divi. It is a very popular theme and has a lot of features that are not found in many other themes.
It is also very easy to use, so anyone can create a website with it.
Another good free theme is called Twenty Fifteen. It is similar to the Divi theme, but has a few modifications that make it easier to use.
It also has a lot of features, so it is perfect for any website.
Overall, there are a few good free WordPress themes, but they are not as popular as the more popular themes. They are worth checking out if you are looking for a good theme, but do not want to spend money on it.
