'Draw chessboard with frame with pure html and css

I have already finished a chessboard with pure HTML and CSS. But as I'm not a designer, and I can't figure out how to do a simple thing. I'm trying to make a frame around the board. I'm using CSS border property to make a margin in table.chessboard element (code below). But that margin expands inside the board and decreases the squares on borders.

What can I do to solve this?

Code:

table.chessboard {
  margin: 80px auto;
  background: #999;
  border: 25px solid #333;
}

td.chessboard {
  width: 70px;
  height: 70px;
}

tr.chessboard:nth-child(odd) td.chessboard:nth-child(even),
tr.chessboard:nth-child(even) td.chessboard:nth-child(odd) {
  background: white;
}

<table class="chessboard">
  <tr class="chessboard">
    <td class="chessboard"></td>
    <!-- line above 8 times -->
  </tr>
  <tr class="chessboard">
    <td class="chessboard"></td>
    <!-- line above 8 times -->
  </tr>
  <tr class="chessboard">
    <td class="chessboard"></td>
    <!-- line above 8 times -->
  </tr>
  <tr class="chessboard">
    <td class="chessboard"></td>
    <!-- line above 8 times -->
  </tr>
  <tr class="chessboard">
    <td class="chessboard"></td>
    <!-- line above 8 times -->
  </tr>
  <tr class="chessboard">
    <td class="chessboard"></td>
    <!-- line above 8 times -->
  </tr>
  <tr class="chessboard">
    <td class="chessboard"></td>
    <!-- line above 8 times -->
  </tr>
  <tr class="chessboard">
    <td class="chessboard"></td>
    <!-- line above 8 times -->
  </tr>

Solution 1:^[1]

I assume you want to make a border around all the cells.

table.chessboard {
    margin: 80px auto;
    background: #999;
    border: 25px solid #333;
    border-collapse: collapse; /* */
}
td.chessboard {
    width: 70px; height: 70px;
    border: 2px solid #333; /* */
}
tr.chessboard:nth-child(odd) td.chessboard:nth-child(even),
tr.chessboard:nth-child(even) td.chessboard:nth-child(odd) {
    background: white;
}

<table class="chessboard">
<tr class="chessboard">
    <td class="chessboard"></td>
    <td class="chessboard"></td>
    <td class="chessboard"></td>
    <td class="chessboard"></td>

    <td class="chessboard"></td>
    <td class="chessboard"></td>
    <td class="chessboard"></td>

<tr class="chessboard">

    <td class="chessboard"></td>
    <td class="chessboard"></td>
    <td class="chessboard"></td>
    <td class="chessboard"></td>
    <td class="chessboard"></td>
    <td class="chessboard"></td>
    <td class="chessboard"></td>

<tr class="chessboard">
