如何在列表元素的下一行缩进文本

Question

>我有一个无序列表：

<ul class="list_arrow2">
    <li>
        <span style="display: inline-block; width: 150px; font-weight: bold;">
            Signup Options </span>&ndash; &nbsp; Describe your signup options 
            that an applicant can choose from. List the signup option type, 
            description, and price. For example, the two signup options might be 
            Customer or Distributor; each option would carry a different description 
            of cost and details.
    </li>
    <li>
        <span style="display: inline-block; width: 150px; font-weight: bold;">
            Order Options </span>&ndash; &nbsp; Indicate any additional purchase 
            options that an applicant may have. This may be in the form of a single 
            item or package item order. For example, you might want to give the 
            applicant a choice to purchase a "starter kit" that includes various 
            products that you sell. Be sure to list the details of these items, 
            including a description and price.
    </li>
    <li>
        <span style="display: inline-block; width: 150px; font-weight: bold;">
            Autoship Options </span>&ndash; &nbsp; This section can be exclusive 
            of the Order Options section or you can include both. The Autoship 
            section is just like the Order Options section except that the applicant 
            is agreeing to receive the order on an monthly, recurring basis. Be 
            sure to include descriptions, pricing, etc.
    </li>
    <li>
        <span style="display: inline-block; width: 150px; font-weight: bold;">
            Payment Options </span>&ndash; &nbsp; List the types of credit cards 
            you accept (Visa, M/C, AMEX, Diners). Also, if you intend on taking 
            personal checks online, or ACH, be sure to add this to your details. 
            If you plan on taking online checks, or ACH, please contact your Account 
            Manager for more details on getting this set up.
    </li>
    <li>
        <span style="display: inline-block; width: 150px; font-weight: bold;">
            Terms and Conditions</span>&ndash; &nbsp; Please provide the full text 
            of your terms and conditions and/or Distributor Agreement. This will 
            be displayed for the applicant to agree to before proceeding with 
            their registration.
    </li>
    <li>
        <span style="display: inline-block; width: 150px; font-weight: bold;">
            Confirmation Message </span>&ndash; &nbsp; Please provide us with 
            the text that is displayed once the applicant successfully signs up. 
            This text is also emailed to the new applicant.
    </li>
    <li>
        <span style="display: inline-block; width: 150px; font-weight: bold;">
            Welcome Message </span>&ndash; &nbsp; Please provide us with the text 
            that is displayed as an introduction to the applicant.
    </li>
</ul>

现在，如果文本溢出到下一行，它将一直向左对齐（例如在顺序选项下的右侧）。 保持列表标题（订单选项）向左对齐的最佳方法是什么，如果描述订单选项的文本溢出到下一行以与自身对齐？

订单选项 - 这是一些文本我对流动的文本很丑订单选项 - 这是一些文本                我非常满腔的文字！

这是我的 CSS

ul.list_arrow, ul.list_arrow2 {
    margin: 0px 0 15px 15px!important;
}
ul.list_arrow li {
    padding: 2px 2px 2px 0px;
    list-style-image: url(../images/icon/arrow_a.gif);
}
ul.list_arrow2 li {
    padding: 2px 2px 2px 0px;
    list-style-image:url(../images/icon/arrow.png)
}
dl.list_arrow, dl.list_arrow2 {
    margin: 0px 0 15px 15px!important;
}
dl.list_arrow dt {
    padding: 2px 2px 2px 0px;
    list-style-image: url(../images/icon/arrow_a.gif);
}
dl.list_arrow2 dt {
    padding: 2px 2px 2px 0px;
    list-style-image:url(../images/icon/arrow.png)
}

Answer 1

你可以缩进跨度，就像这样（在这里小提琴）：

li {
  padding-left:150px;
}
li span {
  margin-left: -150px;
}​

不过，更好的方法是设置一个悬挂缩进（小提琴）：

li {
  margin-left:150px;
  text-indent:-150px;
}

定义列表将更好地满足您的需求。请参阅此 jsFiddle 示例。

.HTML

<dl class="list_arrow2">
    <dt>Signup Options </dt>
    <dd>–&nbsp;&nbsp; Describe your signup options that an applicant can choose 
    from. List the signup option type, description, and price. For example, the 
    two signup options might be Customer or Distributor; each option would carry 
    a different description of cost and details</dd>
    <dt>Order Options </dt>
    <dd>–&nbsp;&nbsp; Indicate any additional purchase options that an applicant 
    may have. This may be in the form of a single item or package item order. For 
    example, you might want to give the applicant a choice to purchase a &quot;starter 
    kit&quot; that includes various products that you sell. Be sure to list the details 
    of these items, including a description and price. </dd>
    <dt>Autoship Options </dt>
    <dd>–&nbsp;&nbsp; This section can be exclusive of the Order Options section
