This structure can make it difficult for assistive technologies (such as screen readers) to understand the structure of content and affect accessibility.

Next, the author proposes several alternatives:

Plan 1: Reversal<h2></h2> and<h3></h3> order. Set the subtitle to<h2></h2> , set the title as<h3></h3> . The author believes that this approach is more reasonable if the subtitle is semantically more important.

Solution 2: Use one<h2></h2> And one

Solution 3: Use<hgroup></hgroup> element. The author tried to use<hgroup></hgroup> Pack the title and subtitles and control the visual order through CSS. But the author points out that this approach may not be friendly enough for screen reader users.

Solution 4: Use a single<h2></h2> , and use<strong></strong> Mark the subtitle. This is semantically more concise and controlled by CSS<strong></strong> , the style of the , achieves visual distinction. The author recommends using punctuation marks such as colons between sub-headings and large titles to make them more semantically coherent.

Solution 5: Use the ARIA role role="doc-subtitle" . The author introduces the ARIA role role="doc-subtitle" to represent subtitles. Although the browser supports this role in varying degrees, overall, it is a viable solution.

Finally, the author also discussed some unrecommended practices, such as using<label></label> Elements or pseudo-elements to achieve visual effects, as these methods affect accessibility and content findability.
