Why does a Dreamweaver cc16, Bootstrap v3.3.6, created, hyperlinked Button set into a PHP 7 created html page, work in current version Opera & Chrome browsers but not in current version IE or Firefox browsers?
Page in question is: https://howtoliveoffthegridnow.com/index.php
The Button in question has the text: =>
FREE: 11 Things To Know Before Going Off The Grid
The Button html code is: =>
`<div align="center" style="font-size: 1.5em">
<button type="button" class="btn btn-lg">
<a href="https://howtoliveoffthegridnow.com/wordpress/get-your-own-off-the-grid-checklist/" title="Access option to download checklist"><strong>FREE: 11 Things To Know Before Going Off The Grid</strong></a>
</button>
</div>`
and the relevant bootstrap.css v3.3.6 is linked conventionally using: =>
`<link rel="stylesheet" type="text/css" href="assets/css/bootstrap.css" />`
This is a critical CTA link so any help in resolving this issue would be most gratefully received. Thank you. /psb
ps: In the case of Firefox, it does not appear to be an issue of Tracking Protection. I turned that off but makes no difference.
Problem found, tested, verified here on a Windows Pro 8.1, 64 bit AMD pc and on an ASUS Windows 8.1 tablet and a Sony Vaio Win Pro 7 Centrino2 laptop. Even works in Safari on the laptop!
