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 Solution 3: Use Solution 4: Use a single Solution 5: Use the ARIA role Finally, the author also discussed some unrecommended practices, such as using The article summarizes the advantages and disadvantages of various methods and suggests that the most appropriate solution should be selected according to the actual situation, with semantics and accessibility priority.

This is visually feasible, but the subtitles may be ignored by screen reader users.<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.<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.role="doc-subtitle" . The author introduces the ARIA role role="doc-subtitle" to represent subtitles.

Load external CSS files using JavaScript conditions, suitable for situations where flexibility is required; 3. Containment on the server side, suitable for scenarios using server-side languages. This approach can optimize website performance and maintainability, but requires balance of modularity and performance.

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.
