在文字后显示所需的星号？

Question

我试图asterisk red star在文本后显示,但文本的宽度不允许在文本后插入星号.见下面的例子

码

<div class="col-sm-4 col-sm-offset-1 required-field">
     @Html.LabelFor(model => model.ContactPhoneNumber, new { @class = "control-label-nobold" })
</div>

生成Html

  <label class="control-label-nobold" for="ContactPhoneNumber">If you wish to be contacted by phone, enter your phone number</label>
</div>

CSS

.required-field:after {
    content: "*";
    font-weight: bold;
    color: red;
}
*, *:before, *:after {
    -webkit-box-sizing: border-box;
    -moz-box-sizing: border-box;
    box-sizing: border-box;
}

页

明星显示下一行

文字的宽度不允许我添加星号

如何在文字旁边添加星标？

Answer 1

添加:after到标签.

.required-field .control-label-nobold:after {
content: "*";
font-weight: bold;
color: red;
}

更新:抱歉,错过了.required-field类.
