Reducing layout shift is crucial for improving your Cumulative Layout Shift (CLS) scores, which measure visual stability. To achieve this, you should focus on reserving space for dynamic content and ensuring elements load predictably.

Example Concept: CLS can be minimized by setting explicit width and height attributes on images and videos, using CSS aspect ratio boxes for responsive media, and avoiding inserting content above existing content without reserving space. This ensures that the layout remains stable as the page loads.

Additional Comment:

Use "min-height" for containers that load dynamic content to prevent shifts.
Preload key web fonts to avoid shifts caused by font loading.
Reserve space for ads and embeds to avoid unexpected layout changes.
Test your site with tools like Lighthouse to identify and fix CLS issues.
