flexbox align column left and right

Learning how to use flexbox, with typical css I could float one of two columns left and another right with some gutter space in-between. How would I do that with flexbox?

#container {
width: 500px;
border: solid 1px #000;
display: -webkit-flex;
display: -ms-flexbox;
display: flex;
}
#a {
width: 20%;
border: solid 1px #000;
}
#b {
width: 20%;
border: solid 1px #000;
height: 200px;
}

<div id="container">
<div id="a">
a
</div>
<div id="b">
b
</div>
</div>




Answer

You could add justify-content: space-between to the parent element. In doing so, the children flexbox items will be aligned to opposite sides with space between them.

Updated Example

#container {
    width: 500px;
    border: solid 1px #000;
    display: flex;
    justify-content: space-between;
}

#container {
    width: 500px;
    border: solid 1px #000;
    display: flex;
    justify-content: space-between;
}

#a {
    width: 20%;
    border: solid 1px #000;
}

#b {
    width: 20%;
    border: solid 1px #000;
    height: 200px;
}
<div id="container">
    <div id="a">
        a
    </div>
    <div id="b">
        b
    </div>
</div>


You could also add margin-left: auto to the second element in order to align it to the right.

Updated Example

#b {
    width: 20%;
    border: solid 1px #000;
    height: 200px;
    margin-left: auto;
}

#container {
    width: 500px;
    border: solid 1px #000;
    display: flex;
}

#a {
    width: 20%;
    border: solid 1px #000;
    margin-right: auto;
}

#b {
    width: 20%;
    border: solid 1px #000;
    height: 200px;
    margin-left: auto;
}
<div id="container">
    <div id="a">
        a
    </div>
    <div id="b">
        b
    </div>
</div>
