I'm new to web development and I'm trying to figure out how to center my form on the page using CSS and HTML. Can someone help me out?
<form action="login.php" method="post">
username: <input type="text" id="txtusername" /><br />
password: <input type="text" id="txtpassword" /><br />
<input type="submit" value="login" />
</form>
To center an item horizontally using CSS, add a div with a specific width and margin: 0 auto. Unfortunately, there isn't a quick fix for vertically centering a page.
<div style="width: 500px; margin: 200px auto 0 auto;">
<form action="login.php" method="post">
Username: <input type="text" id="txtusername" /><br />
Password: <input type="text" id="txtpassword" /><br />
<input type="submit" value="login" />
</form>
</div>
One option is to use position:fixed, but I recommend adjusting the margin-top instead, as shown in the example above.
Check out this JSFiddle example for reference. Enjoy!
Just a tip: the values for the margin property are margin: [top] [right] [bottom] [left], which explains the 200px for top, 0px for bottom, and auto for left and right.
<table border="0" align="center" cellpadding="0" cellspacing="0" width="300">
<tr>
<td>
<form method="post" action="flogin.php">
<table width="100%" cellpadding="7" cellspacing="0" border="0">
<tr>
<td colspan="3"><center><strong>Enter Your Information </strong></center><br /></td><br />
</tr>
<tr>
<td width="30%">First Name</td>
<td width="10%">:</td>
<td width="60%"><input type="text" name="first_name" /></td>
</tr>
<tr>
<td width="30%">Last Name</td>
<td width="10%">:</td>
<td width="60%"><input type="text" name="last_name" /></td>
</tr>
<tr>
<td width="30%">Email Address</td>
<td width="10%">:</td>
<td width="60%"><input type="text" name="email" /></td>
</tr>
<tr>
<td colspan="3"><center><input type="submit" name="submit" /></center><br /></td>
</tr>
</table>
</form>
</td>
</tr>
</table>
To apply the following style, insert it within the <HEAD> tag:
<STYLE type="text/css">
form {
margin: auto;
width: 30em; /* experiment with other values too */
}
</STYLE>
