General Ways to Fix/Improve Your Site
There are several strategies you can employ to minimize main thread work and improve your website's performance. Some of these include:
- Simplifying layouts: Use efficient CSS properties and avoid complex layout techniques that can cause expensive calculations on the main thread. For example, use Flexbox or Grid layout instead of floats or absolute positioning.
- Reducing paint operations: Minimize the number of paint operations by using CSS properties that don't trigger paint, such as transform and opacity. Also, consider using the will-change property to inform the browser of upcoming changes to an element's appearance, allowing it to optimize rendering.
