Subscribe button not working on touch screen/mobile device - html

Question

I made a subscribe button for a mailing list and it works on PC/desktop view, but not on mobile devices (touchscreens).
You can click it and it works on desktop, but it doesn't do anything when you touch it on a mobile device.
It's just plain html and CSS. The code is below along with the media only properties.
Thanks in advance!

Answer 1

you must change the type of button to submit or leave it with out type
just like this
<button type="submit" class="addbut1">Subscribe</button>
or
<button class="addbut1">Subscribe</button>
so the code will be like this
<div class="main">
<form
action="mailto:info#feudalerockband.com?subject=Mailing List"
method="POST"
enctype="text/plain"
name="EmailForm"
id="singular-form">
<button class="shown" type="button" id="subs">Subscribe to our mailing list!</button>
<div id="email-input">
<input type="text" placeholder="Email" id="email" name="Email Address">
<button class="addbut1">Subscribe</button>
</div>
<div id="success">Successfully subscribed to mailing list!</div>
</form>
</div>
