I have a HTML div like,
<div id="tab2" class="tab">
<div class="alarm" id="alarm">
<img src="src/alarm.jpg" style="width: 100%; height: 100%; background-size: contain;">
</div>
</div>
So I want to open this div when a button click. I tried to add a link to the button like this way,
<a href="#tab2" class="button">Get Start</a>
But this is not working. How can I do this. Please help me !
