0.32102 cumulative layout shift collected from the Cumulative Layout Shift API.
These HTML elements contribute most to the Cumulative Layout Shifts of the page. The higher score, the more layout shift.
| Score | HTML Element |
|---|---|
| 0.32102 | <div id="bodyContent" class="content"></div>,<div class="pre-content heading-holder"></div> |
| body > div#mw-mf-viewport > div#mw-mf-page-center > main#content > div#bodyContent,body > div#mw-mf-viewport > div#mw-mf-page-center > main#content > div:eq(1) | |

The elements that have shifted place is highlighted in the image (that have a higher value than 0.01). If the element shifted outside of the viewport, you will not see it there. It can be hard to understand what content that has shifted, if that's the case, checkout the video or the filmstrip of the run.
