<div class="work-wrap">
   <div class="work-item">1</div>
   <div class="work-item">2</div>
   <div class="work-item">3</div>

Answer 1

You can use a flexbox and change the order of the :nth-child(odd) items:

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

.work-item {
  width: 33%;
}

.work-item:nth-child(odd) {
  order: 1;
}

<div class="work-wrap">
  <div class="work-item">1</div>
  <div class="work-item">2</div>
  <div class="work-item">3</div>
  <div class="work-item">4</div>
  <div class="work-item">5</div>
  <div class="work-item">6</div>
</div>
