html align element relative to parent that has a width

given the html below. without changing any properties of the main element, how can i make the html element with id left/right be aligned to the left/right of the main element?

<!doctype html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Document</title>
    <style>
      main {
        width: 400px;
        margin: auto;
        border: 5px solid green;
        text-align: center;
      }
      #left {
        border: 5px solid red;
      }
      #right {
        border: 5px solid blue;
      }
    </style>
  </head>
  <body>
    <main>
      <span id="left">left</span>
      <span id="right">right</span>
      <div>content below left and right</div>
    </main>
  </body>
</html>

using float: left (or right) does align the elements, but it affects how other elements are displayed relative to them.

You can also play with text-align and keep your elements as inline elements

main {
  width: 400px;
  margin: auto;
  border: 5px solid green;
  text-align: justify;
}
main * {
  display: inline-block;
}
main div {
  width: 100%;
  text-align: center;
}

#left {
  border: 5px solid red;
}

#right {
  border: 5px solid blue;
}

<main>
  <span id="left">left</span>
  <span id="right">right</span>
  <div>content below left and right</div>
</main>

You can use float left and right and then apply clear: both; to the following element/s.

Addition after comment: "Normal" content floats next to floated elements, i.e. it's positioned at the left/right borders of the floated elements, as you obviously experienced when trying it. If you want the subsequent element/s to start below a floated element, you can add clear: left or right or both (try these options to see the effect).

main {
  width: 400px;
  margin: auto;
  border: 5px solid green;
  text-align: center;
}

#left {
  border: 5px solid red;
  float: left;
}

#right {
  border: 5px solid blue;
  float: right;
}
#right + div {
  clear: both;
}

<!doctype html>
<html lang="en">

<head>
  <meta charset="UTF-8" />
  <meta name="viewport" content="width=device-width, initial-scale=1.0" />
  <title>Document</title>
</head>

<body>
  <main>
    <span id="left">left</span>
    <span id="right">right</span>
    <div>content below left and right</div>
  </main>
</body>

</html>
