Change color of button after click

I have a question with four answers and I want the button to flash green when the correct answer is selected and red when the wrong answer is selected. How can I do that?page

i want to solve this problem with django and not with javascript.

{% for q in questions %}
                {% if q.kategorie == category and q.flaag == True %}
                        {% if questions.has_next %}
                            <div class="flex-container">
                                <div class="container1">
                                     <div class="position_startButton"><button  type="submit" name="next"  value="{{q.question}}" class="nächstefrage_btn">Nächste Frage!</button></div>

As far as I know, any Django solution needs a redirect or page reload. I assume you're not looking for something like this. Otherwise you can handle it with sending a new context to your template.

Anyway, if you don't want to use JS you can do that with this CSS trick. I'm not aware of the browsers' support status.


<div id="nothing"></div>
<div id="one"></div>
<div class="styleSelector">
    <a href='#nothing'>Nothing</a>
    <a href='#one'>style 1</a>
<main class="scene">
    <div class="carre">


.scene .carre{
  -webkit-transition: all 1s;
  -moz-transition: all 1s;
  transition: all 1s;
#one:target ~ .scene .carre {
