With the help of a WordPress theme, you can design the layout and appearance of your website in the front-end.

For a WordPress interview question about themes, here’s a suitable answer:

“WordPress themes are collections of files (such as templates, stylesheets, and images) that work together to define the look and functionality of a WordPress website. They control the design, layout, and presentation of content on a WordPress site, allowing users to change the appearance of their website without altering the underlying content. Themes can be customized, developed from scratch, or chosen from thousands of pre-made options available in the WordPress theme directory or from third-party theme developers. They are essential components of WordPress, providing users with the flexibility to create websites tailored to their specific needs and preferences.”
