Open expanded block by link in accorderon/spoiler/toggle

The case can be like this – for example, from the main page you need to place links to an internal page where a list of questions and answers is placed. On the inner page, the link should expand the answer to a specific question.

The solution is here:

HTML code:

<div class="info"><span class="target-fix" id="info"></span> 
<!-- 1 Block -->
<div><span class="target-fix" id="info1"></span> <a href="#info1" id="open-info1" title="open">text 1</a> <a href="#info" id="close-info1" title="close">text 1</a>
<div class="info-content">
<p>text 1 text 1</p>
</div>
</div>
<!-- 2 Block -->
<div><span class="target-fix" id="info2"></span> <a href="#info2" id="open-info2" title="open">test 2</a> <a href="#info" id="close-info2" title="close">text 2</a>
<div class="info-content">
<p>text 2 text 2</p>
</div>
</div>
<!-- 3 Block -->
<div><span class="target-fix" id="info3"></span> <a href="#info3" id="open-info3" title="open">test 3</a> <a href="#info" id="close-info3" title="close">test 3</a>
<div class="info-content">
<p>text 3 text 3</p>
</div>
</div>
<!-- 4 Block -->
<div><span class="target-fix" id="info4"></span> <a href="#info4" id="open-info4" title="open">test 4</a> <a href="#info" id="close-info4" title="close">test 4</a>
<div class="info-content">
<p>text 4 text 4</p>
</div>
</div>
<!-- 5 Block -->
<div><span class="target-fix" id="info5"></span> <a href="#info5" id="open-info5" title="open">test 5</a> <a href="#info" id="close-info5" title="close">test 5</a>
<div class="info-content">
<p>text 5 text 5</p>
</div>
</div>
</div>
