customising individual form fields

[jhatter]

Hi,

Using the html and style below, for forms I have created, please can someone show how I can customise it to do the following:

1) extend just the "message" input box so that the height is (say) 3 times more than the other input boxes?

2) make it compulsory to complete name and email in the form and include a small graphic to indicate this.

Thanks in anticipation of your response.

<form method="post" action="fieldset.html">
<fieldset>
<legend> Press &amp; Media Enquiries</legend>

<div>
<label for="fullname">Name:</label>
<input type="text" name="fullname" id="fullname" class="txt" />
</div>

<div>
<label for="fullname">Publication:</label>
<input type="text" name="Publication" id="Publication" class="txt" />
</div>

<div>
<label for="email">Email address:</label>
<input type="text" name="email" id="email" class="txt" />
</div>

<div>
<label for="telephone">Telephone:</label>
<input type="text" name="telephone" id="telephone" class="txt" />
</div>

<div>
<label for="message">Message:</label>
<input type="text" name="message" id="message" class="txt" />
</div>
</fieldset>

<div>
<input type="submit" name="btnSubmit" id="btnSubmit" value="Submit" class="btn" />
</div>
</form>

For the message, just add this:

style="500px"

To the message input, as for the auto-form-checking, you'd need to search around google using keywords like "javascript auto form checking"

Thanks for your reply, excuse my ignorance but where exactly do I put the style="500px" ?

<label for="message">Message:</label>
<input type="text" name="message" id="message" class="txt" style="width:500px"/>
</div>
