查看使用flexbox。
我猜你会做这样的事情:
.container {
display:flex;
flex-flow: row nowrap;
}
.column {
margin: 0 1em;
display: flex;
flex-flow: column nowrap;
justify-content: space-between;
align-items: flex-end;
flex: 1 1 0;
}

<div class = "container">
<div class = "column"> <p>foo foo foo</p><button> button</button></div>
<div class = "column"> <p>foo foo bar
foo foo barfoo barfoo barfoo barfoo
foo foo barfoo barfoo barfoo barfoo
foo foo barfoo barfoo barfoo barfoo
foo foo barfoo barfoo barfoo barfoo
foo foo barfoo barfoo barfoo barfoo
foo barfoo barfoo barfoo bar</p><button> button</button></div>
<div class = "column"> <p>foo RAHA RAHAHAR</p><button> button</button></div>
</div>
