对齐复选框和标签 [英] Align checkbox and label

问题描述

我有一个代码如下的表单：

I have a form which code looks like this:

<div id="right_sidebar">

<form id="your_name" name="your_name" action="#" method="post" style="display: block; "> 
    <fieldset>
        <label for="name">Name</label>
        <input type="text" name="name" id="name" value="">
        <label for="lastname">Last Name</label>
        <input type="text" name="lastname" id="lastname">
                <label for="msg"><a href="#" rel="nofollow" id="msg_toggle">Comment <span class="sp"></span></a></label>
        <textarea name="msg" id="msg" rows="7"></textarea>
        <input type="checkbox" name="agree">
        <label for="agree">Accept the terms</label>
                <button class="blue_button" type="submit">Send</button>
    </fieldset>
    </form>

</div>​

其样式如下CSS：

body {
color: #333;
font: 12px Arial,Helvetica Neue,Helvetica,sans-serif;
}

#right_sidebar {
padding-top: 12px;
width: 190px;
position:relative;
}

form {
background: #EEF4F7;
border: solid red;
border-width: 1px 0;
display: block;
margin-top: 10px;
padding: 10px;
}

form label {
color: #435E66;
    display:block;
font-size: 12px;
    }

form textarea {
border: 1px solid #ABBBBE;
margin-bottom: 10px;
padding: 4px 3px;
width: 160px;
-moz-border-radius: 3px;
border-radius: 3px;
}
form label a {
display: block;
padding-left: 10px;
position: relative;
text-decoration: underline;
}


form label a .sp {
background: #EEF4F7;
height: 0;
left: 0;
position: absolute;
top: 2px;
width: 0;
border-top: 4px solid transparent;
border-bottom: 4px solid transparent;
border-left: 4px solid #333;
}

form button.blue_button {
margin-top: 10px;
vertical-align: top;
}

button.blue_button{
color: white;
font-size: 12px;
height: 22px;
-webkit-border-radius: 3px;
-moz-border-radius: 3px;
border-radius: 3px;
}
button.blue_button {
background-color: #76C8C6;
border: 1px solid #7798B7;
text-shadow: 1px 1px 0px #567C9E;
}

如您所见，该复选框位于标签顶部。我希望两者都在同一条线上。因此，它看起来像 []接受条款。以及如何使文本与复选框垂直对齐。

​As you can see the checkbox is on top of the label. I would like both to be "on the same line". So, it would look like "[ ] Accept the terms". And how would I make that the text is vertically aligned to the checkbox.

我该怎么办？

推荐答案

一个选项是修改复选框后面的 label 元素的样式：

One option is to amend the style of the label element that follows the checkbox:

​input[type=checkbox] + label {
    display: inline-block;
    margin-left: 0.5em;
    margin-right: 2em;
    line-height: 1em;
}

但是，这有点脆弱，因为 margin s有点武断（右边距纯粹是将以下按钮强制移至下一行） 。同样，属性等于选择器也可能在较旧的浏览器中引起问题。

This is, however, somewhat fragile as the margins are a little arbitrary (and the margin-right is purely to force the following button to the next line). Also the attribute-equals selector may cause problems in older browsers.

Alien先生在评论中暗示，实际上使用此选择器将复选框本身作为目标很容易-符号：

As implied, in comments, by Mr. Alien it is actually easier to target the checkbox itself with this selector-notation:

input[type=checkbox] {
    float: left;
    margin-right: 0.4em;
}
