Adding asterisk to required fields in Bootstrap 3
My HTML has a class called .required that is assigned to required fields.
Here is the 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>
I added the following to my CSS;
.form-group .required .control-label:after {
content:"*";color:red;
}
Still that does not give a red * around the required fields. What am I missing here? Isn't there a direct way in Bootstrap 3 to introduce * to required fields?
EDIT
The * in terms and conditions does not appear immediately to a checkbox. How to fix this?
Use .form-group.required without the space.
.form-group.required .control-label:after {
content:"*";
color:red;
}
Edit:
For the checkbox you can use the pseudo class :not(). You add the required * after each label unless it is a checkbox
.form-group.required:not(.checkbox) .control-label:after,
.form-group.required .text:after { /* change .text in whatever class of the text after the checkbox has */
content:"*";
color:red;
}
Note: not tested
You should use the .text class or target it otherwise probably, try this html:
<div class="form-group required">
<label class="col-md-2 control-label"> </label>
<div class="col-md-4">
<div class="checkbox">
<label class='text'> <!-- use this class -->
<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>
Ok third edit:
CSS back to what is was
.form-group.required .control-label:after {
content:"*";
color:red;
}
HTML:
<div class="form-group required">
<label class="col-md-2"> </label> <!-- remove class control-label -->
<div class="col-md-4">
<div class="checkbox">
<label class='control-label'> <!-- use this class as the red * will be after control-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>
Assuming this is what the HTML looks like
<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>
To display an asterisk on the right of the label:
.form-group.required .control-label:after {
color: #d00;
content: "*";
position: absolute;
margin-left: 8px;
top:7px;
}
Or to the left of the label:
.form-group.required .control-label:before{
color: red;
content: "*";
position: absolute;
margin-left: -15px;
}
To make a nice big red asterisks you can add these lines:
font-family: 'Glyphicons Halflings';
font-weight: normal;
font-size: 14px;
Or if you are using Font Awesome add these lines (and change the content line):
font-family: 'FontAwesome';
font-weight: normal;
font-size: 14px;
content: "\f069";
.form-group .required .control-label:after should probably be .form-group.required .control-label:after. The removal of the space between .form-group and .required is the change.
The other two answers are correct. When you include spaces in your CSS selectors you're targeting child elements so:
.form-group .required {
styles
}
Is targeting an element with the class of "required" that is inside an element with the class of "form-group".
Without the space it's targeting an element that has both classes. 'required' and 'form-group'
use simple css,
.myform .required:after {
content: " *";
color: red;
font-weight: 100;
} <form class="myform">
<div class="col-md-12">
<label for="xxx_fname" class="form-label required">First Name</label>
<input type="text" class="form-control" id="xxx_fname" >
</div>
<div class="col-md-12">
<label for="xxx_lname" class="form-label required">Last Name</label>
<input type="text" class="form-control" id="xxx_lname" >
</div>
</form
