如何对齐标签并垂直选择框（中间）

Question

在那里的CSS大师出局，我无法弄清楚使得第一个标签/选择对而不中间对齐的CSS，但第二个在中间保持一致。

查看下面的图像中的问题。我的目标是使第一个标签/选择对align在中间对齐，了解使其发生的CSS规则。

<div class="pure">
    <form class="pure-form-inline">
        <div class="pure-g">
            <div class="pure-u labelArea">
                <label>Choose Project:</label>
            </div>
            <div class="pure-u-1-4">
                <select></select>
            </div>
        </div>
        <div class="pure-control-group">
            <label>Choose Customer:</label>
            <select></select>
        </div>
    </form>
</div>

Answer 1

一种简单的方法是给出label元素的线路高度等于下拉阵选择器的高度。但是，此解决方案仅取决于您的标签仅是单行文本，如果您有任何多线的标签，它将不起作用，并且您应该使用上面详述的vertical-align方法。

label {
    line-height:25px;
}

Answer 2

label, select {
    display: inline-block;
    vertical-align: middle;
}

.

Answer 3

You have additional divs around the first label/select pair, which force this behaviour.

If you remove the unnecessary divs around the first label/select pair and add the same class as in the second, you should be fine

<div class="pure">
    <form class="pure-form-inline">
        <div class="pure-control-group">
            <label>Choose Project:</label>
            <select></select>
        </div>
        <div class="pure-control-group">
            <label>Choose Customer:</label>
            <select></select>
        </div>
    </form>
</div>

Answer 4

Try with this vertical align fix:

/* Vertical Align Fix */

.valign:before {
    content:"";
    height:100%;
    display:inline-block;
    vertical-align:middle;
}
.valign > * {
    display: inline-block;

}
.valign-m { vertical-align: middle; }

Give the class (.valign) to the parent (The div containing the select)

And this other class to the inner elements (select + label)

See if it works.
