How to wrap items in flexbox for smaller screens? - html

Question

I'm trying to create a layout for different resize. I need to reach the result in these images here:
I have this code:
.container {
position: relative;
display: flex;
align-items: stretch;
}
.item {
background-color: black;
box-sizing: border-box;
padding: 20px;
flex: 2;
color: #fff;
}
.item:nth-child(2) {
background-color: grey;
flex: 1
}
.item:nth-child(3) {
background-color: green;
flex: 0.5;
}
#media screen and (max-width: 990px) {
.container {
height: auto;
display: table;
}
.item:nth-child(2) {
float: left;
}
.item:nth-child(3) {
float: right;
}
}
<section class="container">
<div class="item">
<h2>title1</h2>
<hr>You'll notice that even though this column has far more content in it, instead of the other columns ending early, they size themselves to meet the end of this column vertically.</div>
<div class="item">
<h2>title2</h2>
<hr>Normally, the only way to achieve this would be either a hack, or to set all boxes to min-height.
</div>
<div class="item">
<h2>title3</h2>
<hr>This is a column with not much content.
</div>
</section>
Here there's a codepen https://codepen.io/darudev/pen/pyBrzL
Problem is in 990px resize view, I don't find solution to create the same view as "mockup".
Is there someone that can help me or give me some suggestions?
Thank you.

You don't need the table and float properties in your code.
#media screen and (max-width: 990px) {
.container {
height: auto;
display: table;
}
.item:nth-child(2) {
float: left;
}
.item:nth-child(3) {
float: right;
}
}
The entire layout can be made with flexbox.
Here's the solution: When the screen resizes smaller than 990px, allow flex items to wrap and give the first item a 100% width, which forces the following items to the next line.
.container {
display: flex;
}
.item {
background-color: black;
box-sizing: border-box;
padding: 20px;
flex: 2;
color: #fff;
}
.item:nth-child(2) {
background-color: grey;
flex: 1;
}
.item:nth-child(3) {
background-color: green;
flex: 0.5;
}
#media screen and (max-width:990px) {
.container { flex-wrap: wrap; }
.item:first-child { flex-basis: 100%; }
}
<section class="container">
<div class="item">
<h2>title1</h2>
<hr>You'll notice that even though this column has far more content in it,
instead of the other columns ending early, they size themselves to meet the end
of this column vertically.</div>
<div class="item">
<h2>title2</h2>
<hr>Normally, the only way to achieve this would be either a hack, or to set
all boxes to min-height.</div>
<div class="item">
<h2>title3</h2>
<hr>This is a column with not much content.
</div>
</section>
