Semantics in design system is all about ensuring that each design element conveys its intended meaning and purpose clearly. In product design, this means making design choices that guide users naturally through their journey. For example, buttons and icons should be intuitively placed and visually represent their function to make the experience smoother. When semantics are applied properly in design, it helps users interact with the product more effectively and with less confusion.

Semantics also plays a role in structuring web pages in a way that reflects the true purpose of each element. Semantic UI, as a design framework, emphasizes using HTML elements with meaningful names that describe their function. This practice not only improves the look of the interface but also boosts accessibility by ensuring screen readers and other assistive technologies can understand the layout and functionality of the page.

By understanding and applying semantics in design, teams can create more intuitive products where every element has a clear role, leading to a seamless user experience.
