I've a custom checkbox. What I want is to to open a bootstrap modal when the checkbox is checked. I want a bootstrap modal to open just as when clicked a button. Hope you understood my question. How can I do it.
HTML CODE
/*
          ----------------------------------------------
                              CHECKBOX
          ----------------------------------------------

/* Base for label styling */
[type="checkbox"]:not(:checked),
[type="checkbox"]:checked {
  position: absolute;
  left: -9999px;
}
[type="checkbox"]:not(:checked)+label,
[type="checkbox"]:checked+label {
  position: relative;
  padding-left: 25px;
  cursor: pointer;
}
/* checkbox aspect */
