Elements in a flex container are not wrapping

Question

When I try to insert block elements in a flex container, they all stay on the same line as if they were inline-blocks.

I would like the two first div's to be on the same line, and the last one to be on a second line. Sadly, that doesn't seem to work.

Anyone have any idea ?

 <div style="display: flex"> <div style="display: inline-block"> This is an inline block element </div> <div style="display: inline-block"> This is an inline block element </div> <div style="display: block"> This is a block element </div> </div> 

Answer 1

An initial setting of a flex container is flex-wrap: nowrap . This means flex items are forced to remain in a single line.

You can override the default with flex-wrap: wrap .

The display value of flex items is ignored in flex layout.

A flex container, which is an element with display: flex or display: inline-flex , establishes a flex formatting context . Although similar to a block formatting context , there are differences.

One difference is that children of a flex container ignore the display property.

Another difference is that, in a flex container, margins don't collapse, and the float and clear properties have no effect.

A flex container also comes with several default settings. Among them:

• justify-content: flex-start - flex items will stack at the start of the line
• flex-shrink: 1 - flex items are allowed to shrink and will not overflow the container
• align-items: stretch - flex items will expand to cover the cross-size of the container
• flex-direction: row - flex items will align horizontally
• flex-wrap: nowrap - flex items are forced to stay in a single line

Note the last two items.

Flex items will line up in a row and cannot wrap.

If you want to have two flex items on the first line, and a third item on the second line, allow the container to be multi-line with flex-wrap: wrap .

 .container { display: flex; flex-wrap: wrap; } .box { flex: 0 0 45%; height: 50px; margin: 5px; background-color: lightgreen; border: 1px solid #ccc; } 

 <div class="container"> <div class="box"></div> <div class="box"></div> <div class="box"></div> </div> 

Also, if you want flex containers to display inline, use display: inline-flex not display: flex . These are comparable to display: inline-block and display: block .

Answer 2

• use flex-wrap:wrap in parent because by default the flex-wrap is nowrap

• use flex-basis:50% in child, to divide both inline-block elements in same size.

 *, *::before, *::after { box-sizing: border-box } body { margin: 0 } .flex { display: flex; flex-wrap: wrap } .flex div { flex: 0 50%; /*change to 1 50% to see the difference */ border: 1px solid black; padding: 10px } 

 <div class="flex"> <div> This is an inline block element </div> <div> This is an inline block element </div> <div> This is a block element </div> </div>
