CSS Column and Chrome Error: Avoiding Flow Overflow Content

Question

When used column-count, it seems to clip any overflow content .

#columns {
  -webkit-column-count: 1;
  -webkit-column-gap: 10px;
  /*-webkit-column-fill: auto;*/
  -moz-column-count: 1;
  -moz-column-gap: 10px;
  /*-moz-column-fill: auto;*/
  column-count: 1;
  column-gap: 10px;
  /*column-fill: auto;*/
  border: 1px solid red;
  overflow: visible;
}
.pin {
  width: 100%;
  display: inline-block;
  padding: 10px;
  margin-bottom: 5px;
}

<div id="columns">

  <div class="pin">

    <a href="#">
      <span class="onsale">Sale!</span>
      <img src="#.jpg" />
    </a>
    <h3>Product 1</h3>
    </a>
  </div>

</div>

Run codeHide result

Result:

Any ideas how I can fix this?

EDIT 1:

This seems to be a bug in Chrome .

everything is fine in Firefox:

EDIT 2:

span.onsale {
    min-height: 3.236em;
    min-width: 3.236em;
    padding: .202em;
    font-size: 1em;
    font-weight: 700;
    position: absolute;
    text-align: center;
    line-height: 3.236;
    top: -.5em;
    left: -.5em;
    margin: 0;
    border-radius: 100%;
    background-color: $highlight;
    color: $highlightext;
    font-size: .857em;
    -webkit-font-smoothing: antialiased;
}

Answer 1

I'm not sure how you create your own .onsale, so I stylized my own way.

If you use position:relativein .pin, then position:absolute, you can achieve what you want.

: webkit-column-count:1 Chrome, 1 , , .onsale position:absolute

#columns {
 
  border: 1px solid red;
  
}
.pin {
  width: 100%;
  display: inline-block;
  padding: 10px;
  margin-bottom: 5px;
  position: relative
}
.onsale {
   min-height: 3.236em;
    min-width: 3.236em;
    padding: .202em;
    font-size: 1em;
    font-weight: 700;
    position: absolute;
    text-align: center;
    line-height: 3.236;
    top: -.5em;
    left: -.5em;
    margin: 0;
    border-radius: 100%;
    background-color: lightgreen;
    color: white;
    font-size: .857em;
    -webkit-font-smoothing: antialiased;
}

<div id="columns">
  <div class="pin">
    <a href="#">
      <span class="onsale">Sale!</span>
      <img src="//placehold.it/300x300" />
    </a>
    <h3>Product 1</h3>
  </div>
  <div class="pin">
    <a href="#">
      <span class="onsale">Sale!</span>
      <img src="//placehold.it/300x300" />
    </a>
    <h3>Product 2</h3>
  </div>
</div>
