The gender select color in form_wizards.html

[iwantmyway]

Hi, I am newbie in bootstrap.
In form_wizards.html , there is a Gender selection label. The color of it does not change after the selection.
<label class="btn btn-secondary" data-toggle-class="btn-primary" data-toggle-passive-class="btn-secondary"> <input type="radio" name="gender" value="male" class="join-btn"> &nbsp; Male &nbsp; </label>
I want to ask how can I change the color after the gender is selected ? Should I modify the css or the javascript ?

You can modify the javascript code accordingly.Use javascript to check whether radio button is selected and change color accordingly.
