Semantic HTML enhances accessibility by using meaningful tags that convey the structure and purpose of content. This allows screen readers and other assistive technologies to interpret web pages more effectively, providing context to users who may have visual impairments.

This clarity not only enhances user experience but also makes it easier for developers to maintain the codebase and ensure consistent styling across the site.
