CSS one char per line-CodePudding

I need all the text written in i a div to be vertical, like one character per line and centered.

The only way i've achieved is giving the div a fixed width of width: 7%; and a word-break: break-all;

Is there any way using CSS to achieve this with no fixed width?

.flex-container {
    display: flex;
    border: 1px solid #000000;
}

.flex-container > div {
    width: 400px;
    height: 300px;
    text-align: center;
    line-height: 75px;
    font-size: 30px;
}

.flex-container > div:nth-child(odd) {
    background-color : #62d962;
}

.flex-container > div:last-child {
    display: flex;
    justify-content: flex-end;
}

.flex-container > div:last-child div {
    width: 7%;
}

.flex-container div:last-child div:nth-child(odd){
    background-color: #65e9e3;
    word-break: break-all;
    line-height: 1em;
    padding: 1em 0;
}

<div >
  <div></div>
  <div></div>
  <div>
    <div>Box</div>
    <div></div>
    <div>Box</div>
    <div></div>
    <div>Box</div>
  </div>
</div>

You can use writing-mode and text-orientation CSS properties, to achieve the desired output.

.flex-container {
    display: flex;
    border: 1px solid #000000;
}

.flex-container > div {
    width: 400px;
    height: 300px;
    text-align: center;
    line-height: 75px;
    font-size: 30px;
}

.flex-container > div:nth-child(odd) {
    background-color : #62d962;
}

.flex-container > div:last-child {
    display: flex;
    justify-content: flex-end;
}

.flex-container > div:last-child div {
    writing-mode: vertical-rl;
    text-orientation: upright;
}

.flex-container div:last-child div:nth-child(odd){
    background-color: #65e9e3;
    line-height: 1em;
    padding: 1em 0;
}

<div >
  <div></div>
  <div></div>
  <div>
    <div>Box</div>
    <div></div>
    <div>Box</div>
    <div></div>
    <div>Box</div>
  </div>
</div>
