We’ve been using the Top and Bottom separators on our site and just had to remove them from the homepage because GT Metrix/PageSpeed made reference to content shift. When we checked the issue, it was through use of the Separators.
Here is the code referenced in GT Metrix which caused the CLS issue:
#cs-content > div#x-section-3 > div.x-section-separator > svg.angle-top-in
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" viewBox="0 0 100 100" preserveAspectRatio="none" class="angle-top-in" style="fill: rgb(197, 232, 108);">
The entire CLS 1 score was attributable to this Dom Element alone.
Please help as it’s a great feature, but unfortunately, Google considers CLS to be one of their determining features.
