Make Flex Item Expand On Hover, Shrinking Its Siblings

I'm trying to solve a flexbox issue where I want to have three divs per row, first equal in size, but when hovering a div, that one grows and the other ones on the same row shrink.

Solution 1:

Do I have to wrap each row in a separate container or is there a way to solve this?

You would need to wrap each row in a separate container.

The layout is not possible with flexbox because wrapping is enabled.

This means that items in a single row can't be made to expand while shrinking its siblings without triggering a wrap. There's nothing to force the siblings to shrink, when they can just wrap.

Without flex-wrap: wrap the row length has a hard limit. You can then give an item any large length on hover (I use flex-basis: 100%, in my example), and it can expand while shrinking its siblings, without any wrapping concerns.

.container {
  display: flex;
}

.box {
  flex-basis: 33.33%;
}

.box:hover {
  flex-basis: 100%;
}


/* for demo only */.box {
  transition: .5s;
  border: 1px dashed red;
  box-sizing: border-box;
}

<divclass="container"><pclass="box">Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut la bore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud. Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt
    ut labore et dolore magna aliqua. </p><pclass="box">Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud. Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt
    ut labore et dolore magna aliqua. </p><pclass="box">Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud. Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt
    ut labore et dolore magna aliqua. </p></div><divclass="container"><pclass="box">Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut la bore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud. Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt
    ut labore et dolore magna aliqua. </p><pclass="box">Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud. Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt
    ut labore et dolore magna aliqua. </p><pclass="box">Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud. Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt
    ut labore et dolore magna aliqua. </p></div>

Solution 2:

I have tried my best to get them aligned in the same container but they don't seem to fit there. It is better for you to take them in separate containers.

By this, they will look good and you could do some easy stylings if you need to apply separately.

Here is the Fiddle

.container {
  display: flex;
  flex-wrap: wrap;
  width: 100%;
  justify-content: space-between;
}

.box {
  width: 30%;
  flex: 112%;
  transition: all 0.3s ease-in-out;
}

.box:hover {
  flex-grow: 2;
}

<divclass="container"><divclass="box"><p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud. Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt
      ut labore et dolore magna aliqua. </p></div><divclass="box"><p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud. Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt
      ut labore et dolore magna aliqua. </p></div><divclass="box"><p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud. Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt
      ut labore et dolore magna aliqua. </p></div></div><divclass="container"><divclass="box"><p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud. Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt
      ut labore et dolore magna aliqua. </p></div><divclass="box"><p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

      ut labore et dolore magna aliqua. </p></div><divclass="box"><p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
