WordPress starter themes and frameworks differ from one another, but they both speed up the development process of building new themes and websites. They’re hallmarks of WordPress’ open-source nature, giving developers head starts in creating new products.
With such a huge user base, WordPress is the world’s most popular CMS. It is also the easiest to use, so it follows that there are many people using it who have little idea of coding and are more business or design oriented. The challenge is thus to create functionality for this non-technical user base that will enable them to create a theme/design/template based on their ideas, without touching any code.
