WordPress themes cater to all sorts of user preferences and needs. Each comes with customizable designs, with the option to modify its code, insert widgets, or add plugins.
There are WordPress themes for every kind of site – from eCommerce websites to food blogs. Generic themes are also available if you prefer them over niche-specific choices.
