Markdown Template / style like "read the docs" for documents

thanks…

now it looks great with this improved CSS code

.important {
  border-color: #ffb100; 
  background-color: #fff9e6;
  border-left: 5px solid #ffb100;
  border-right: 5px solid #ffb100;
  border-radius: 5px;
}
.important h3 {
  background-color: #ffb100;
  padding-top: 0.5em;
  padding-bottom: 0.5em;
  padding-left: 1em;
  color: white;
}
.important h3:before {
    content: "⚠️ ";
}
.important p {
  padding-left: 1em;
  padding-right: 1em;
}
.important p:first-of-type {
  padding-top: 0.5em;
}
.important p:last-of-type {
  padding-bottom: 0.5em;
  border-bottom: 5px solid #ffb100;
}

it looks like this

Indeed, even slightly “nicer” border margins than in @ThorstenG’s example
