I don’t see that you have even passed your form to your template from your view. When you call render it should look like this:

    render(request,"login.html", {'login_form': login_form})

Now if you are using login_form correctly in the template like so:

    <div class='form-group'>
        {{login_form.username}}
        {{login_form.password}}
    </div>

That will handle your errors for you and display them. If you want more fine grained control you could do this:

{% for field in login_form %}
    <div class="fieldWrapper">
        {{ field.errors }}
        {{ field.label_tag }} {{ field }}
        {% if field.help_text %}
        <p class="help">{{ field.help_text|safe }}</p>
        {% endif %}
    </div>
{% endfor %}

Now you can modify around each individual element. Please read this for more information on form rendering and this example: https://docs.djangoproject.com/en/1.10/topics/forms/#form-rendering-options

EDIT:

    <form action="/login/" method="post" autocomplete="off">
{% csrf_token %}
<div class="form-group marb20 {% if login_form.errors.username %}errorput{% endif %}">
    {{login_form.username}}        
</div>
<div class="form-group marb8 {% if login_form.errors.password %}errorput{% endif %}">
   {{login_form.password}}
</div>

<div class="error btns login-form-tips" id="jsLoginTips">{% for key,error in login_form.erroes.items %}{{error}}{% endfor %}{{ msg }}</div>
 <div class="auto-box marb38">

    <a class="fr" href="forgetpwd.html">forget the password？</a>
 </div>
 <input class="btn btn-green" id="jsLoginBtn" type="submit" value="sign_in > " />
{% csrf_token %}
</form>

You have to pass just login_form as shown below if form is not valid. Because you are accessing login_form.errors.username in your template.

def post(self, request):
    login_form = LoginForm(request.POST)
    if login_form.is_valid():
        ....
    else:
        return render(request,"login.html",{"login_form":login_form})
