Examples
Excluding a subtree from a container's timing
In this example, the <div> and its contents are excluded from the "hero" container's timing, while the image still contributes to it.
html
<section containertiming="hero">
<img src="hero.jpg" alt="" />
<div containertimingignore>
<!-- content painted here does not count toward the "hero" container's timing -->
</div>
</section>
For examples of how to use the Container Timing API to get timing information, see PerformanceContainerTiming.
