CSS3 Flexbox: Align-Items: Baseline

The align-items:baseline; property will position the flex-items at the baseline of the container. The baseline value causes flex-items to be aligned based on the content of the flex-items. This is best explained by the following example which shows the result of using the baseline value:

<style>
.flex-container {
    display: -webkit-flex;
    display: flex;
    -webkit-align-items: baseline;
    align-items: baseline;
    width: 400px;
    height: 250px;
    background-color: lightgrey;
}
.flex-item1 {
    background-color: cornflowerblue;
    width: 100px;
    margin: 10px;
    padding: 12px;
}
.flex-item2 {
    background-color: cornflowerblue;
    width: 50px;
    height: 50px;
    margin: 10px;
}
.flex-item3 {
    background-color: cornflowerblue;
    width: 100px;
    height: 100px;
    margin: 10px;
    padding: 20px;
}
</style>
<body>
<div class="flex-container">
    <div class="flex-item1">This is flex item 1</div>
    <div class="flex-item2">flex item 2</div>
    <div class="flex-item3">This is flex item 3</div>
</div>
</body>
This is flex item 1
flex item 2
This is flex item 3

Padding was added to the first and third flex-items to make each flex-item a different size. Notice how the text inside each flex-items are lined up.
