Overlapping CSS flexbox items in Safari

Question

What's the correct CSS to force Safari to not overlap flex items within a default flex container?

Safari seems to give too much width to flex items with lots of content.

Safari: (v8.0.8 on Mac OS X 10.10.5 Yosemite)

The flex items display fine in Chrome and Firefox.

Chrome:

CSS:

main {
   display: flex;
   border: 3px solid silver;
   }
main >div {
   background-color: plum;
   margin: 10px;
   }

HTML:

<main>
   <div>
      Doh!!!!!!!!!!!
   </div>
   <div>
      Lorem ipsum dolor sit amet, consectetur adipiscing
      elit, sed do eiusmod tempor incididunt ut labore et
      dolore magna aliqua. Ut enim ad minim veniam.
   </div>
</main>

Answer 1

The element is shrinking. You need to set the flex-shrink property to 0 on the shrinking element.

main >div:first-child {
  -webkit-flex: 0;
  flex-shrink: 0;
}

Answer 2

I also had a similar issue where flex box direction changed to column overlapped items on iPad. The issue was with the flex: 0 1 0; property applied to child element. Give the base value auto. flex: 0 1 auto;

.parent{
    display: flex;
    flex-direction: column;
}
.parent .child{
    flex: 0 1 auto;
}
