Web design: HTML forms

The form used to submit messages to the guestbook hasn’t changed either in many years. The original markup was

<h2 id="writeMsg">Write a new message</h2>

<form id="msg" method="post" action="gb_post.asp">

<p>Subject:<br /><input type="text" name="fTitle" style="width:400px;"/></p>
<p>Your name:<br /><input type="text" name="fName" style="width:400px;" /></p>
<p>E-mail:<br /><input type="text" name="fMail" style="width:400px;" /></p>
<p>Website:<br /><input type="text" name="fWeb" style="width:400px;" /></p>
<p>Message text:<br /><textarea name="fMsg" cols="74" rows="12" style="width:600px; height:200px;"></textarea></p>

<li>Also include the website protocol (most often <code>http://</code>).
(The <code>mailto:</code> e-mail protocol is understood and should not be entered.)</li>
<li>By submitting a message you accept the "<a href="gb_rules.asp">terms of use</a>".</li>

<p><strong>Security check</strong><br />Enter the sum to unlock the questbook!<br />
<input type="text" name="security1" readonly="readonly" value="16" />
<input type="text" name="security2" readonly="readonly" value="26" />
<input type="text" name="security3" />

<p><input type="submit" value="Send message" /> <input type="reset" value="Reset" /></p>


the rendering of which is given below.

Rendering of the above HTML

I have now changed this to

<section id="writeMsg">

<h2>Write a message</h2>

<form method="post" action="gb_post.asp">

<label for="InputTitle">Subject:</label>
<input id="InputTitle" name="fTitle" type="text" size="50" required="required">
<label for="InputName">Your name:</label>
<input id="InputName" name="fName" type="text" size="50" required="required">
<label for="InputMail">Your e-mail address (optional):</label>
<input id="InputMail" name="fMail" type="email" size="50">
<label for="InputWeb">Your website (optional):</label>
<input id="InputWeb" name="fWeb" type="url" size="50">
<small>Include the protocol, e.g. <kbd>http://</kbd>.</small>
<label for="InputMsg">Message text:</label>
<textarea id="InputMsg" name="fMsg" cols="74" rows="12" required="required"></textarea>

<legend>Security check</legend>
<p>Compute the sum to unlock the guestbook.</p>
<input name="security1" readonly="readonly" value="3" type="text" size="4"> +
<input name="security2" readonly="readonly" value="19" type="text" size="4"> =
<input name="security3" type="text" size="4" autocomplete="off" required="required"
oninput="security3.setCustomValidity(parseInt(security1.value) + parseInt(security2.value) !=
parseInt(security3.value) ? 'Incorrect value.' : '')">

<input id="InputAcceptRules" type="checkbox" name="fAcceptRules" value="yes" required="required" />
<label for="InputAcceptRules">I have read and I accept the
<a href="gb_rules.asp" target="_blank">terms of use</a>.</label>

<input value="Send message" type="submit">
<input value="Reset" type="reset">



which looks like

Rendering of the above HTML

There are quite a few improvements:

In order to style this, a very small piece of CSS is needed:

#writeMsg label + input, #writeMsg label + textarea {
display: block;
#writeMsg fieldset {
display: inline;

Indeed, I clearly want text fields and similar controls to be positioned below their labels, but I do want checkboxes and radio buttons, which precede their labels, to remain inline.

The second rule is needed to reduce the width of the fieldset.

Notice that labels, fieldsets, and legends are not new to HTML5 (and neither is good general design). On the other hand, the new types of input controls (type=email and type=url), the autocomplete attribute, and client-side validation are HTML5 additions.
