Flexbox: Layout with Rows

Question

My HTML is like the following example

<div id="wrapper"> <div id="a">a</div> <div id="b">b</div> <div id="c">c</div> <div id="d">d</div> </div> 

On the desktop, I would like divs to appear next to each other, which, of course, is trivial.

On a mobile phone, I need a tabular layout similar to the following

b, c and d have a flexible height, so you have to adapt to this.

Is it possible to do without wrapping b, c and d in a separate div?

Answer 1

Yes, you can do this completely with flexbox ... of course, you will need to choose the width for the first div with the smaller viewports, but I assume that you keep this in mind, ready for the required media request.

 #wrapper { height: 100vh; width: 90vw; border: 1px solid grey; display: flex; flex-direction: column; flex-wrap: wrap; margin: 10px auto; } #wrapper div { flex: 1 0 auto; border: 1px solid white; background: lightblue; text-align: center; } #a { flex-grow: 1; height: 100%; flex-basis: 50%; } @media screen and (min-width: 640px) { #a { height: auto; flex-grow: none; flex-basis: auto; } } 

 <div id="wrapper"> <div id="a">a</div> <div id="b">b</div> <div id="c">c</div> <div id="d">d</div> </div>

Use only flexbox when necessary: ​​on the desktop version:

 * { box-sizing: border-box; } body { margin: 0; } #a { background: tomato; } #b { background: forestgreen; } #c { background: dodgerblue; } #d { background: orange; } #wrapper { overflow: hidden; position: relative; } #wrapper > div { float: left; width: 50%; margin-left: 50%; padding: 5px; } #wrapper > #a { position: absolute; height: 100%; margin-left: 0; } @media all and (min-width: 768px) { #wrapper { display: flex; } #wrapper > div { margin-left: 0; } #wrapper > #a { position: relative; height: auto; } 

 <div id="wrapper"> <div id="a">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed non risus. Suspendisse lectus tortor, dignissim sit amet, adipiscing nec, ultricies sed, dolor.
