我的 HTML 有一个名为 .required
的类,它被分配给所需的字段。
下面是 HTML:
<form action="/accounts/register/" method="post" role="form" class="form-horizontal">
<input type='hidden' name='csrfmiddlewaretoken' value='brGfMU16YyyG2QEcpLqhb3Zh8AvkYkJt' />
<div class="form-group required">
<label class="col-md-2 control-label">Username</label>
<div class="col-md-4">
<input class="form-control" id="id_username" maxlength="30" name="username" placeholder="Username" required="required" title="" type="text" />
</div>
</div>
<div class="form-group required"><label class="col-md-2 control-label">E-mail</label><div class="col-md-4"><input class="form-control" id="id_email" name="email" placeholder="E-mail" required="required" title="" type="email" /></div></div>
<div class="form-group required"><label class="col-md-2 control-label">Password</label><div class="col-md-4"><input class="form-control" id="id_password1" name="password1" placeholder="Password" required="required" title="" type="password" /></div></div>
<div class="form-group required"><label class="col-md-2 control-label">Password (again)</label><div class="col-md-4"><input class="form-control" id="id_password2" name="password2" placeholder="Password (again)" required="required" title="" type="password" /></div></div>
<div class="form-group required"><label class="col-md-2 control-label">first name</label><div class="col-md-4"><input class="form-control" id="id_first_name" maxlength="30" name="first_name" placeholder="first name" required="required" title="" type="text" /></div></div>
<div class="form-group required"><label class="col-md-2 control-label">last name</label><div class="col-md-4"><input class="form-control" id="id_last_name" maxlength="30" name="last_name" placeholder="last name" required="required" title="" type="text" /></div></div>
<div class="form-group required"><label class="col-md-2 control-label"> </label><div class="col-md-4"><div class="checkbox"><label><input class="" id="id_tos" name="tos" required="required" type="checkbox" /> I have read and agree to the Terms of Service</label></div></div></div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-primary">
<span class="glyphicon glyphicon-star"></span> Sign Me Up!
</button>
</div>
</div>
</form>
我在 CSS 中添加了以下内容;
.form-group .required .control-label:after {
content:"*";color:red;
}
但仍然没有在所需字段周围给出红色 *
。我错过了什么?难道在 Bootstrap 3中没有一种直接的方法将 *
引入到所需的字段中吗?
*
的条款和条件不会立即出现在复选框中。如何解决这个问题?
