What does proper tagging in HTML ensure for users with disabilities?

Proper tagging in HTML enhances navigation and interaction for users with disabilities by providing a structured and semantic layout of the content. When HTML elements are correctly tagged, assistive technologies like screen readers can interpret the content more accurately and convey it to users in a meaningful way. For example, correct use of heading tags (h1, h2, etc.) allows users to understand the hierarchy of information and navigate quickly through the sections of a webpage.

Additionally, proper tagging helps to ensure that visual and interactive elements, like forms and buttons, are accessible. Assistive technologies rely on these tags to provide context and functionality, helping users to interact with web content effectively. This means that users with disabilities can navigate websites more easily and engage with the content without encountering barriers, significantly improving their web experience.
