I'm in the process of creating an app landing page using the Bootstrap framework (Bootstrap 4 alpha). I have used text-align:center in the jumbotron id to center everything, but the email form is not aligning properly.
Is there a way to center align the email form and ensure that it stays centered regardless of the width of the webpage?
This is the code in the stylesheet.
.jumbotron
{
background-image: url(background.jpg);
text-align: center;
margin-top: 50px;
}
Here is the main code.
<div class="jumbotron" id="jumbotron">
<h1 class="display-3">My Awesome App!</h1>
<p class="lead">This is why YOU should download this fantastic app!</p>
<hr class="m-y-2">
