Making a CSS accordion open by clicking on plus sign OR the label

Question

I found a great CSS/html codepen that allows me to view text in an accordion fashion when clicking on text inside the label element of class question, but there's only one problem I have with it:

The problem:

I can't use the plus-signs of class plus to also toggle the accordion. Instead, in the current implementation the accordions only open and allow me to view the answer if I click on the text inside the label elements of class question.

As things stand now, if I click on the plus sign (of class .plus), nothing happens. Can someone help me to modify this code so that clicking on either the plus-sign of class plus or the question text itself inside of the label element toggles the answers' visibility?

Answer 1

I would move the plus sign into a pseudo element of the label, since it doesn't need to be in the markup and is just for display anyways.

  padding: 0 60px 0 0;
}

.centerplease {
  margin: 0 auto;
  max-width: 270px;
  font-size: 40px;
}

.question {
  position: relative;
  background: #8FBC8F;
  margin: 0;

.question:before {

Answer 2

Just place 'plus' within label tag, and of course, fix the positioning.

  <label for="question1" class="question">
    <div class="plus">+</div>This is the question that will be asked?
  </label>

Answer 3

A simple fix for this would be to give your .plus class pointer-events: none;. This allows for the mouse to click through the plus icon, hitting the label behind it.
