[.🇨🇺] Post Color Highlighting 2022-11-16

One day I was checking the Invision Community website and I came across this feature, so I set out to replicate it for Xenforo.
Step number 1:
We create a template called xf_post_highligh and copy the following code:

<div class="message-cell message-cell--main">

.admin_highlight {
border: 2px solid red;
box-shadow: 0 0 10px red;
}

[data-container-key="node-X"]
{
.admin_highlight {
border: 2px solid red;
box-shadow: 0 0 10px red;
}
    }
