Customize Tooltip

Hi!

I posted now as a new topic. Here's what I want to do. I want to take advantage of the tooltip
in order to secure EAT for the mighty Google. What I like to do is something like this:

My Tooltip Wish image

The problem is that the code on https://generatepress.com/forums/topic/tooltip-stylesheet/
it generates some errors on my end. I use this code:

/* Tooltip */
.tool-tip {
position: relative;
}
.tool-tip-wrap {
position: absolute;
top: 0;
left: -20px;
padding-top: 2em;
display: block;
width: 400px;
opacity: 0;
transition: opacity 0.1s ease-out;
}
.tool-tip-content {
display: block;
padding: 20px;
border: 1px solid #ddd;
background-color: #fff;
box-sizing: border-box;
color: #111;
}
.tool-tip:hover .tool-tip-wrap {
opacity: 1;
}
.tool-tip-wrap:after {
content: '';
position: absolute;
display: block;
width: 0;
height: 0;
top: 1.6em;
left: 20px;
border-left: 8px solid transparent !important;
border-right: 8px solid transparent !important;
border-top: 0 !important;
border-bottom: 8px solid #ddd;
}

Now, on my offline site, I have these errors (show in front of images):

FIRST ERROR

SECOND ERROR

For the sharing button, I use the Ultimate Social Media Icons PLUS plugin - free on WP.

One thing: my site is NOT online, I have it on my computer using Local for WP (https://localwp.com/).
From my experience, sometimes plugins and CSS enter in conflict on Local.

So I would be happy if you can confirm it works online. I use this code and implement it as a shortcode
on main posts: [sc name="names"][/sc] (using Shotcoder plugin - https://wordpress.org/plugins/shortcoder/)

And lastly, would be nice to customize as in my first image, but have no clue what to add - round image,
bold title, and social icons. But it's not mandatory, can live without those.

Thanks!
