Make Divs of Different Heights Fill Vertical Space on New Line

make divs of different heights fill vertical space on new line

Your best option is to use Masonry but if you insist on CSS only solution then you should use columns
Here is Demo

.wrapper {
 -webkit-column-count: 3; /* Chrome, Safari, Opera */
 -moz-column-count: 3; /* Firefox */
  column-count: 3;
 -webkit-column-gap: 0; /* Chrome, Safari, Opera */
 -moz-column-gap: 0; /* Firefox */
  column-gap: 0;
  width: 100vw;
}

.wrapper div {
  display: inline-block;
  width: 100%;
  vertical-align: top;

}

<div class="wrapper">
    <div class="item" style="height: 400px; background-color: #ddd"></div>
    <div class="item" style="height: 200px; background-color: #000"></div>
    <div class="item" style="height: 200px; background-color: #ececec"></div>
    <div class="item" style="height: 700px; background-color: #DC0F0F"></div>
    <div class="item" style="height: 400px; background-color: #B429A2"></div>
    <div class="item" style="height: 200px; background-color: #009EBA"></div>
    <div class="item" style="height: 200px; background-color: #694141"></div>
    <div class="item" style="height: 400px; background-color: #29B436"></div>
    <div class="item" style="height: 200px; background-color: #74B2BD"></div>
    <div class="item" style="height: 700px; background-color: #DCDA0F"></div>
</div>

Make a div fill the height of the remaining screen space

2015 update: the flexbox approach

There are two other answers briefly mentioning flexbox; however, that was more than two years ago, and they don't provide any examples. The specification for flexbox has definitely settled now.

Note: Though CSS Flexible Boxes Layout specification is at the Candidate Recommendation stage, not all browsers have implemented it. WebKit implementation must be prefixed with -webkit-; Internet Explorer implements an old version of the spec, prefixed with -ms-; Opera 12.10 implements the latest version of the spec, unprefixed. See the compatibility table on each property for an up-to-date compatibility status.

(taken from https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Flexible_boxes)

All major browsers and IE11+ support Flexbox. For IE 10 or older, you can use the FlexieJS shim.

To check current support you can also see here:

Working example

With flexbox you can easily switch between any of your rows or columns either having fixed dimensions, content-sized dimensions or remaining-space dimensions. In my example I have set the header to snap to its content (as per the OPs question), I've added a footer to show how to add a fixed-height region and then set the content area to fill up the remaining space.

html,body {  height: 100%;  margin: 0;}
.box {  display: flex;  flex-flow: column;  height: 100%;}
.box .row {  border: 1px dotted grey;}
.box .row.header {  flex: 0 1 auto;  /* The above is shorthand for:  flex-grow: 0,  flex-shrink: 1,  flex-basis: auto  */}
.box .row.content {  flex: 1 1 auto;}
.box .row.footer {  flex: 0 1 40px;}

<!-- Obviously, you could use HTML5 tags like `header`, `footer` and `section` -->
<div class="box">  <div class="row header">    <p><b>header</b>      <br />      <br />(sized to content)</p>  </div>  <div class="row content">    <p>      <b>content</b>      (fills remaining space)    </p>  </div>  <div class="row footer">    <p><b>footer</b> (fixed height)</p>  </div></div>
