How to make slideToggle worked when clicking on a different div elements with the same class?

Good day! How to make so that when you click on the contents diva with the class "issue", unfolded it and its contents? Questions can be many. I would not want anyone to assign their id.
<div class="issue-block">
<div class="issue">Question 1: Kind of account Earth from the Sun?</div>
<div class="otvet">Here is the answer to the question.</div>
