请问如何使用 css3 水平对齐 div 标签的两个内容。我的封闭主体的总宽度为 950 像素，我将第一个 div 标签的宽度指定为 470 像素。我的假设是第二个 div 标签将占据 480 像素的剩余空间，但它在定位时没有占据

这是html代码

</div>
<!--There Should be a separator (vertical)-->
<form action="/" method="post">
    <div class="right">Tell us what you think or feel about this site
        <div id="right-UserComment">
            <input type="text" name="Name" placeholder="Name" required />
            <input type="email" name="Email" placeholder="Email Address" required />
            <br />
            <textarea cols="40" rows="3" wrap="hard" required placeholder="What's up?" name="comments"></textarea>
        </div>
        <button type="submit" value="submit">Send</button>
    </div>
</form>

这是CSS，它包括容器、左右div标签css。

container{
    width:950px;
    margin:0;
    margin-left:auto;
    margin-right:auto;
    border-style:solid;
    background-color:orange;
}



.left {
    width:450px;
    margin-left:10px;
}

Answer 2

这是一个带有答案的 JS Fiddle。我使用基于百分比的宽度而不是像素宽度：http://jsfiddle.net/4nHr8/

CSS如下：

.left {
    float:left;
    width: 40%;
    padding: 0 2.5%;
    display:inline-block;
    border-left: 2px solid #333;
}
.right {
    float:left;
    width: 40%;
    padding: 0 2.5%;
    display: inline-block;
}

检查我在外部 div 上添加的以下 html 并为 div 添加样式
