使图像占据Flex项目的全高

Question

I have a container that is 100vh (minus the fixed nav height).

<section class="container">

Inside this container I have some text:

 <div class="text">
    <p>title</p>
 </div>

Which can be of any length as the content is dynamic.

Below this text I have an image:

 <div class="image">
    <img src="https://s-media-cache-ak0.pinimg.com/736x/d1/a6/64/d1a664bca214bf785a293cbc87950fc4.jpg">
 </div>

The image needs to fill the rest of the 100vh (- nav height) container.

I use:

.container{
    display:flex;
    flex-flow: column nowrap;
    ....

Fiddle

The issue I am having is that I need the image to be the height of the rest of the space.

How can I do this? In my fiddle, if your screen is small it is being cut off and if your screen is large it does not fill the space. Height: 100% fails to work, making it too large.

Flex solutions only please, no table tricks - thanks!

Answer 1

Make the image container ( .image ) a flex container with height: 100% .

You can then fine-tune the image's aspect ratio and alignment with object-fit / object-position .

 nav { position:fixed; background:grey; width:100%; height: 100px; } main { padding-top: 100px; } .container { display:flex; flex-flow: column nowrap; height: calc(100vh - 100px); background: green; border: 3px solid brown; } .text { background: yellow; } /* ***** NEW ***** */ .image { display: flex; justify-content: center; height: 100%; } img { width: 100%; object-fit: contain; } 

 <nav>Nav</nav> <main> <section class="container"> <div class="text"><p>title</p></div> <div class="image"> <img src="https://s-media-cache-ak0.pinimg.com/736x/d1/a6/64/d1a664bca214bf785a293cbc87950fc4.jpg"> </div> </section> <section class="container"> <div class="text"><p>hello</p></div> <div class="image"> <img src="https://s-media-cache-ak0.pinimg.com/736x/d1/a6/64/d1a664bca214bf785a293cbc87950fc4.jpg"> </div> </section> </main> 

Revised Fiddle

Note that the object-fit property is not supported by IE. For more details and a workaround see: https://stackoverflow.com/a/37127590/3597276

Answer 2

Maybe not exactly what you wanted, but if you move the image to a div and use it as a background, you can get the desired effect.

Fiddle

HTML: Nav

title

<section class="container">
  <div class="text">
    <p>hello</p>
  </div>
   <div class="imageWrap">
     <div class="image"></div>
   </div>
</section>
</main>

CSS:

nav {
  background: grey;
  width: 100%;
  height: 100px;
  position: fixed;
}
main{
  padding-top: 100px;
}
.container{
    display: flex;
    flex-flow: column nowrap;
    height: calc(100vh - 100px);
    background: green;
    border: 3px solid brown;
}
.imageWrap {
  flex: 1;
  display: flex;
}
.image {
  flex: 1;
  background-size: contain;
  background-repeat: no-repeat;
  background-image: url(https://s-media-cache-ak0.pinimg.com/736x/d1/a6/64/d1a664bca214bf785a293cbc87950fc4.jpg)
}
.text{
    background: yellow;
}
