Creating a show-more/show-less info box with + and - sign : <p>I want to create a box that has information in it that expands onclick of a '+' icon at the top right. The box should expand and include more information about that specific section and the '+' should transition into a '-' to allow the user to collapse the box to the original format that it was before.</p>

<p>The animation would be similar to  <a href="https://www.w3schools.com/howto/howto_css_menu_icon.asp" rel="nofollow noreferrer">https://www.w3schools.com/howto/howto_css_menu_icon.asp</a> </p>

<p>In simple terms: I need a "show-more/show-less" box that expands/collapses but with a '+' and '-' sign instead of 'show-more' or 'show-less'</p>

<p>How can I achieve this?</p>
