I'm trying to make a website form look like this where the right side of text fields are aligned
When I change the size of the screen, the text fields are no longer in alignment. How can I keep them aligned regardless of screen size?
Here is my code:
<head>
<META HTTP-EQUIV="Content-type" CONTENT="text/html; charset=UTF-8">
<title>Coat Request Form</title>
</head>
<body>
<form target="_top" action="https://www.salesforce.com/servlet/servlet.WebToLead?encoding=UTF-8" method="POST">
<p>
<input type=hidden name="oid" value="00Di0000000gO95">
<input type=hidden name="retURL" value="http://www.empowermentplan.org/#!thank-you/jiwpq">
<span style="display:inline-block" margin-right="30px">
<label class="required" for="first_name" style="display:block">First Name</label>
<input id="first_name" maxlength="40" name="first_name" size="20" type="text" required /><br>
</span>
<span style="display:inline-block">
<label class="required" for="last_name" style="display:block">Last Name</label>

</span>
<label style="display:block">Who are the coats for?</label>
<textarea id="00Ni000000H0Cy2" name="00Ni000000H0Cy2" rows="3" type="text" wrap="soft"></textarea><br>
