How to change line break order when using bidi-override and right-to-left direction with CSS?

I’m using a little script which hides mail addresses using the fact that you can reverse text by using unicode-bidi: bidi-override and direction: rtl.

<span>
    <span>moc.e</span>
    <span>ussi-</span>
    <span>kaerb</span>
    <span>-enil</span>
    <span>@sser</span>
    <span>dda-l</span>
    <span>iam-t</span>
    <span>set</span>
</span>

With the following output:

[email protected]

Unfortunately, this doesn’t work when the mail address is too long and contains a line-break:

The reverse text direction causes that the end of the mail address comes before the line break:

-break-issue.com
test-mail-address@line

Check out the code snippet:

div {
  display: inline-block;
  margin: 0 10px 10px 0;
  padding: 10px;
  vertical-align: top;
  font-size: small;
}

.small {
  border: 1px solid red;
  width: 170px;
}

.big {
  border: 1px solid green;
  width: 280px;
}

strong {
  display: block;
  margin-bottom: 30px;
}

span.eeb-rtl {
  unicode-bidi: bidi-override !important;
  direction: rtl !important;
  display: inline !important;
}

span.eeb-rtl span.eeb-sd {
  display: inline !important;
  padding-left: 0 !important;
}
<div class="small">
  <strong>Small container</strong>
  <span class="eeb eeb-rtl">
    <span class="eeb-sd">moc.e</span><span class="eeb-sd">ussi-</span><span class="eeb-sd">kaerb</span><span class="eeb-sd">-enil</span><span class="eeb-sd">@sser</span><span class="eeb-sd">dda-l</span><span class="eeb-sd">iam-t</span><span class="eeb-sd">set</span>
  </span>
</div>
<div class="big">
  <strong>Big container</strong>
  <span class="eeb eeb-rtl">
    <span class="eeb-sd">moc.e</span><span class="eeb-sd">ussi-</span><span class="eeb-sd">kaerb</span><span class="eeb-sd">-enil</span><span class="eeb-sd">@sser</span><span class="eeb-sd">dda-l</span><span class="eeb-sd">iam-t</span><span class="eeb-sd">set</span>
  </span>
</div>

Is there any CSS option to correct the line breaking order in a small container?

The result should be:

test-mail-address@line-
break-issue.com

    This is a very dirty solution but hey it works ¯_(ツ)_/¯ . I changed the classnames because I was having a hard time following the code btw.

    div {
  display: inline-block;
  margin: 0 10px 10px 0;
  padding: 10px;
  vertical-align: top;
  font-size: small;
}

.small {
  border: 1px solid red;
  width: 170px;
}

.big {
  border: 1px solid green;
  width: 280px;
}

strong {
  display: block;
  margin-bottom: 30px;
}



.text-piece {
  unicode-bidi: bidi-override;
  direction: rtl;
}

/* Add enough to cover all of your segments */
.text-piece:nth-last-child(1) {order:1}
.text-piece:nth-last-child(2) {order:2}
.text-piece:nth-last-child(3) {order:3}
.text-piece:nth-last-child(4) {order:4}
.text-piece:nth-last-child(5) {order:5}
.text-piece:nth-last-child(6) {order:6}
.text-piece:nth-last-child(7) {order:7}
.text-piece:nth-last-child(8) {order:8}
.text-piece:nth-last-child(9) {order:9}
.text-piece:nth-last-child(10) {order:10}

.wrapper-span {
  display: flex;
  flex-wrap: wrap;
}
    <div class="small">
  <strong>Small container</strong>
  <span class="wrapper-span">
    <span class="text-piece">moc.e</span><span class="text-piece">ussi-</span><span class="text-piece">kaerb</span><span class="text-piece">-enil</span><span class="text-piece">@sser</span><span class="text-piece">dda-l</span><span class="text-piece">iam-t</span><span class="text-piece">set</span>
</div>
<div class="big">
  <strong>Big container</strong>
  <span class="wrapper-span">
    <span class="text-piece">moc.e</span><span class="text-piece">ussi-</span><span class="text-piece">kaerb</span><span class="text-piece">-enil</span><span class="text-piece">@sser</span><span class="text-piece">dda-l</span><span class="text-piece">iam-t</span><span class="text-piece">set</span>
  </span>
</div>

    I’m assuming you want to prevent web scraping, so you’re displaying email like this. If you are already using "little script", the best solution is to improve it. With your permission I am trying to reproduce your script. I’m giving you a javascript code example but you can easily transfer to any other programming language like php, becase I think this one should happen on the backend side.

    const email = '[email protected]';

small.innerHTML = convertEmail(email);
big.innerHTML = convertEmail(email);

function convertEmail(emailString) {
  const email = emailString.split('').reverse().join('');
  const emailArray = email.match( new RegExp(`.{1,${5}}`, 'g') ).map( (el, index, arr) => `<span style="order: ${index * -1}">${el}</span>` );
  return `<span class="emial">${emailArray.join('')}</span>`;
}
    body {
  display: flex;
  gap: 16px;
}

#small {
  border: solid 1px red;
  padding: 10px;
  width: 170px;
}

#big {
  border: solid 1px green;
  padding: 10px;
}

.emial {
  display: flex;
  flex-wrap: wrap;
}

.emial span {
  unicode-bidi: bidi-override;
  word-break: keep-all;
  direction: rtl;
}
    <div id="small"></div>
<div id="big"></div>
