How to style a echo function with multiple variables

I would like my code to display two variables on the same echo function, however, I want them to style them differently. Making the 'id' smaller and a different color. I do not know how to separate the two variables so I can add some code in-between.

I tried to use a second echo function, but then the 'id' displays at the bottom, separate from the 'quote' function.

echo "<p class='dash'>---------</p>","<p class='center' style='color:white' align='center'>" .$row['quote'] .$row['id'];

The output will just display like this (bold text for output):
--------
"This is the quote variable"1

However, I need is displayed like this:

-------
"This is the quote variable"
1

So basically what is needed is some way to add style to the second one. (I already styled the first one)

Solution

Another way which eliminates use of dot concatenation operator:

<?php
$row["quote"] = "This is the quote";
$row["id"] = 1;
$p = [];
$p[0] = "<p class='dash'>---------</p>\n";
$p[1] = "<p class='center' style='color:white' align='center'>$row[quote]<br>\n$row[id]</p>\n";
echo $p[0],$p[1];

Example HTML implementation:

.dash {
  color: blue;
  font-weight: 300;
}

.center {
  text-algin: center font-weight:900;
}

body {
background:navy
}

<p class='dash'>---------</p>
<p class='center' style='color:white' align='center'>This is the quote<br> 1
</p>
