How can I make my flexbox layout take 100% vertical space?
set the wrapper to height 100%
.vwrapper {
display: flex;
flex-direction: column;
flex-wrap: nowrap;
justify-content: flex-start;
align-items: stretch;
align-content: stretch;
height: 100%;
}
and set the 3rd row to flex-grow
#row3 {
background-color: green;
flex: 1 1 auto;
display: flex;
}
demo
You should set height
of html, body, .wrapper
to 100%
(in order to inherit full height) and then just set a flex
value greater than 1
to .row3
and not on the others.
.wrapper, html, body {
height: 100%;
margin: 0;
}
.wrapper {
display: flex;
flex-direction: column;
}
#row1 {
background-color: red;
}
#row2 {
background-color: blue;
}
#row3 {
background-color: green;
flex:2;
display: flex;
}
#col1 {
background-color: yellow;
flex: 0 0 240px;
min-height: 100%;/* chrome needed it a question time , not anymore */
}
#col2 {
background-color: orange;
flex: 1 1;
min-height: 100%;/* chrome needed it a question time , not anymore */
}
#col3 {
background-color: purple;
flex: 0 0 240px;
min-height: 100%;/* chrome needed it a question time , not anymore */
}
<div class="wrapper">
<div id="row1">this is the header</div>
<div id="row2">this is the second line</div>
<div id="row3">
<div id="col1">col1</div>
<div id="col2">col2</div>
<div id="col3">col3</div>
</div>
</div>

EDIT, as mention by @Basj , the code can be shorten . We can also nowdays use grid widely implemented : Below an example with grid for the visitors :
body {height: 100vh;display: grid;grid-template-rows:auto auto 1fr;margin: 0;background-color: orange;grid-template-columns:240px 1fr 240px;}
[id^=row]{grid-column:1/-1}
#row1 {background-color: red;}
#row2 {background-color: blue;}
#row3 {background-color: green;}
#col1 {background-color: yellow;}
#col3 {background-color: purple;}
<div id="row1">this is the header</div>
<div id="row2">this is the second line</div>
<div id="col1">col1</div>
<div id="col2">col2</div>
<div id="col3">col3</div>
