Flexbox and rtl

Question

I have following layout, but in rtl copy button goes to the left. How do I keep copy button on the right like it was no rtl?

I tried some solutions here but I cannot make it work: flexbox align column left and right

.data {
  display: flex; /* displays flex-items (children) inline by default */
  align-items: flex-start; /* vertical alignment / optional but recommended / if you don't want that flex-items match in height, which by default they do (default value of stretch, which makes them fill the flex-containers height and where the height of all items is dictated by the height of the "tallest" one) / you can also try the value of center */
  max-width: 400px;
  direction: rtl;
}

.code {
  color: #fff;
  margin: 0;
  padding: 8px !important;
  line-height: 1.2;
  font-size: 11px;
  background: #bbb;
  border: 1px solid #333;
  word-wrap: break-word;
  /*float: left; not necessary*/
}

.copy {
  color: #ccc;
  /*display: inline-block; not necessary*/
  padding: 3px !important;
  font-size: 12px;
  cursor: pointer;
  border: 1px solid #999;
  /*float: right; not necessary*/
  margin-left: 10px; /* design purposes */
}

<div class="data">
  <p class="code">Praesent molestie. Nunc Venenatis Sapien Ultrices Dui. Vivamus dolor. Integer vel ante. Proin felis. Maecenas non nisl eu mi hendrerit fringilla.</p>
  <div class="copy">COPY</div>
</div>

Answer 1

You can just apply flex-direction: row-reverse to your flex container. In this case you don't have to set order for every flex item.

.data {
  display: flex; /* displays flex-items (children) inline by default */
  align-items: flex-start; /* vertical alignment / optional but recommended / if you don't want that flex-items match in height, which by default they do (default value of stretch, which makes them fill the flex-containers height and where the height of all items is dictated by the height of the "tallest" one) / you can also try the value of center */
  max-width: 400px;
  flex-direction: row-reverse; /* new */
}

.code {
  color: #fff;
  margin: 0;
  padding: 8px !important;
  line-height: 1.2;
  font-size: 11px;
  background: #bbb;
  border: 1px solid #333;
  word-wrap: break-word;
  /*float: left; not necessary*/
}

.copy {
  color: #ccc;
  /*display: inline-block; not necessary*/
  padding: 3px !important;
  font-size: 12px;
  cursor: pointer;
  border: 1px solid #999;
  /*float: right; not necessary*/
  margin-left: 10px; /* design purposes */
}

<div class="data">
  <p class="code">Praesent molestie. Nunc Venenatis Sapien Ultrices Dui. Vivamus dolor. Integer vel ante. Proin felis. Maecenas non nisl eu mi hendrerit fringilla.</p>
  <div class="copy">COPY</div>
</div>

Please note that direction: rtl should be used for languages written from right to left (like Hebrew or Arabic), not for reversing your layout.

Use the order property.

By default, all flex items are set to order: 0, which means their appearance in the source dictates their order in the layout.

You can change the visual order of flex items using positive and negative integers.

.data {
  display: flex;
  align-items: flex-start;
  max-width: 400px;
  direction: rtl;
}

.code {
  color: #fff;
  margin: 0;
  padding: 8px !important;
  line-height: 1.2;
  font-size: 11px;
  background: #bbb;
  border: 1px solid #333;
  word-wrap: break-word;
}

.copy {
  order: -1; /* NEW */
  color: #ccc;
  padding: 3px !important;
  font-size: 12px;
  cursor: pointer;
  border: 1px solid #999;
}

<div class="data">
  <p class="code">Praesent molestie. Nunc Venenatis Sapien Ultrices Dui. Vivamus dolor. Integer vel ante. Proin felis. Maecenas non nisl eu mi hendrerit fringilla.</p>
  <div class="copy">COPY</div>
</div>

Of course, you can also achieve what you want by simply switching the order of the elements:

.data {
  display: flex;
  align-items: flex-start;
  max-width: 400px;
  direction: rtl;
}

.code {
  color: #fff;
  margin: 0;
  padding: 8px !important;
  line-height: 1.2;
  font-size: 11px;
  background: #bbb;
  border: 1px solid #333;
  word-wrap: break-word;
}

.copy {
  color: #ccc;
  padding: 3px !important;
  font-size: 12px;
  cursor: pointer;
  border: 1px solid #999;
}

<div class="data">
  <div class="copy">COPY</div><!-- now this element is listed first -->
  <p class="code">Praesent molestie. Nunc Venenatis Sapien Ultrices Dui. Vivamus dolor. Integer vel ante. Proin felis. Maecenas non nisl eu mi hendrerit fringilla.</p>
</div>
