Minimalist web design is popular for many reasons, especially for:
There are no unnecessary details and distractions – it is easier to perceive the content, search for the necessary information, and focus on reading or choosing a product.
Simple site navigation and ease of checkout. You don’t need to understand the interface for a long time and get used to it.
High download speed. Since there are no “heavy” elements on the site, there are no problems loading content.
