What the issue is

Using heading tags (h1, h2, h3, etc.) for styling purposes rather than to structure content hierarchically misleads users who rely on assistive technologies. For example, choosing an <h4> tag because it visually matches the desired text size, despite it being a primary section title that logically should be an <h1> or <h2>. This misuse of headings disrupts the document's structure, leading users to misinterpret the level of importance of various sections on the page.

What the issue is

Using headings (h1, h2, h3, etc.) improperly by skipping levels in the page structure can make it confusing for users who rely on assistive technologies to navigate web content. For example, moving directly from an h1 to an h3 heading without an intervening h2 disrupts the hierarchical structure of a page.
