Eliminate render-blocking JavaScript and CSS in above-the-fold content
Your page has 6 blocking script resources and 12 blocking CSS resources. This causes a delay in rendering your page.

None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.

  Consider Fixing:
Leverage browser caching
Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.

Leverage browser caching for the following cacheable resources:

Optimize images
Properly formatting and compressing images can save many bytes of data.

Optimize the following images to reduce their size by 17KiB (38% reduction).

  • Compressing and resizing https://www.nih.gov/sites/all/themes/nih/images/nih-logo-color.png could save 9.7KiB (99% reduction).
  • Compressing https://www.nih.gov/sites/all/themes/nih/images/generated/icons-2x-s6278c9c16d.png could save 7.4KiB (21% reduction).

Prioritize visible content
Your page requires additional network round trips to render the above-the-fold content. For best performance, reduce the amount of HTML needed to render above-the-fold content.

The entire HTML response was not sufficient to render the above-the-fold content. This usually indicates that additional resources, loaded after HTML parsing, were required to render above-the-fold content. Prioritize visible content that is needed for rendering above-the-fold by including it directly in the HTML response.

  • Only about 8% of the final above-the-fold content could be rendered with the full HTML response snapshot:19.

Some of the links/buttons on your webpage may be too small for a user to easily tap on a touchscreen. Consider making these tap targets larger to provide a better user experience.

The following tap targets are close to other nearby tap targets and may need additional spacing around them.

  • The tap target <a href="#main-content" class="element-invisi…ment-focusable">Skip to main content</a> is close to 1 other tap targets final.
