I am very new in web languages, still learning. So, I created a landing page (mostly using bootstrap) as a github page. For the submit button, i put the following code in html:
<input type="submit" value="Click to subscribe" name="subscribe" id="mc-embedded-subscribe" class="button btn btn-outline-danger">
Here btn btn-outline-danger refers to the style sheet of bootstrap. Now the button is showing up as it should be on phones and other browsers (I tested with Opera). But with firefox it shows something like this
. But it should have been like this.
Any help why is this happening?
