Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
The -webkit-box-reflect
CSS property lets you reflect the content of an element in one specific direction.
/* Direction values */ -webkit-box-reflect: above; -webkit-box-reflect: below; -webkit-box-reflect: left; -webkit-box-reflect: right; /* Offset value */ -webkit-box-reflect: below 10px; /* Mask value */ -webkit-box-reflect: below 0 linear-gradient(transparent, white); /* Global values */ -webkit-box-reflect: inherit; -webkit-box-reflect: initial; -webkit-box-reflect: unset;

Specifications
Not part of any standard. The standard way to do reflection in CSS is to use the CSS element()
function.
