Align items using flex

Question

I have a requirement as shown below:

|[]                  [][]|

One element at left side of the viewport and two elements on right side of the viewport. To learn display: flex, I am trying this layout without wrapping the elements.

Is this layout possible with flexbox?

Here is the HTML:

<div class="parent">
    <div class="child child--left"></div>
    <div class="child child--right"></div>
    <div class="child child--right"></div>
</div>

I tried using align-items and align-self but no use. Please help.

CSS:

.parent{
     display: flex;  // flexbox
}

You can use margin-left:auto in the div you need in the right side:

.parent {
  display: flex;
  height: 100px;
  width: 100%;
}

.child {
  flex: 0 0 20px;
  border: solid 1px green;
}

.child--right {
  margin-left: auto;
}

<div class="parent">
  <div class="child"></div>
  <div class="child child--right"></div>
  <div class="child"></div>
</div>

you need to use a spacer defined as flex:auto; in order to align the flex-boxes as intended: DEMO

CSS

.parent{
  display:flex;
}
.spacer{
  flex:auto;
}

and your HTML would be:

<div class="parent">
    <div class="child child--left"></div>
    <div class="spacer"></div>
    <div class="child child--right"></div>
    <div class="child child--right"></div>
</div>

You can use flex to fill a space

body {
  margin: 0;
}

.flex {
  display: flex;
  background: purple;
  width: 100%;
  height: 75px;
}
.item {
  background: orange;
  width: 50px;
  height: 50px;
  margin: 12.5px;
}
.filler {
  flex-grow: 1;
}

<div class="flex">
  <div class="item"></div>
  <div class="filler"></div>
  <div class="item"></div>
  <div class="item"></div>
</div>

You'll notice I've added a div with the class filler and set it to have flex-grow: 1; This means that div will always take up the remaining space.

Applying: margin-<direction>: auto on the child of a flex item will essentially float the item in the opposite direction (with none of the complications of float).

.child--right {
  margin-left: auto;
}

A way to do this without using an extra filler element is to use auto-margins.

CSS

.child--left {
    margin-right: auto; /* <== here's the auto margin */
}

It will add a margin to the right of .child--left which will fill up the available space within .parent (essentially acting like there's a filler element between the left and right children, but actually without the filler element)
