How to make an alternating responsive grid?

Time:11-11

I have a 2-column grid as follows: some text, followed by an image related to that text. On the other row the order is flipped:

| Text 1           | Image for Text 1 |
| Image for Text 2 | Text 2           |
| Text 3           | Image for Text 3 |

I created a standard grid to achieve it (jsfiddle: https://jsfiddle.net/6yxLpqmr/), extract from source:

<div class="pure-g">
  <article class="pure-u-1 pure-u-md-1-2">Text 1</article>
  <article class="pure-u-1 pure-u-md-1-2">Image for Text 1</article>
  <article class="pure-u-1 pure-u-md-1-2">Image for Text 2</article>
  <article class="pure-u-1 pure-u-md-1-2">Text 2</article>
  <article class="pure-u-1 pure-u-md-1-2">Text 3</article>
  <article class="pure-u-1 pure-u-md-1-2">Image for Text 3</article>
  <!-- many more alternating articles like this -->
</div>

However, once the grid is collapsed on a narrow screen, it results in:

Text 1
Image for Text 1
Image for Text 2
Text 2
Text 3
Image for Text 3
<...>

Which is un-intuitive.

Q1: How can I change the result to:

Image for Text 1
Text 1
Image for Text 2
Text 2
Image for Text 3
Text 3

Q2: is it possible to write CSS in a way that creates the alternation by itself (without generating the CSS of course), while semantically keeping the HTML "in order" (image/text/image/text/...)?

It is better to create child box and use flex-direction: column-reverse. Check out the jsFiddle here.

            <article class="pure-u-1 pure-u-md-1-2">Image for Text 1</article>
        </div>
        <div class="box">

            <article class="pure-u-1 pure-u-md-1-2">Text 2</article>
        </div>
    </div>

CodePudding user response:

You can use order along with an appropriate media query to achieve that:

@media screen and (max-width: 425px) {
  .pure-g > article:nth-child(2) {
    order: -1;
  }
}

Check out the updated jsFiddle here or the snippet below.

.pure-g > article:nth-child(2) {
  order: -1;
}
