mailchimp with modx - indent

Hi

I would like to ask how you can have the same indention to this code:
<p>[+MailChimp.message+]</p>
<form method="post" action="[~[*id*]~]">
<label>First Name: <input type="text" name="mc_FNAME" value="" /></label>

<label>Last Name: <input type="text" name="mc_LNAME" value="" /></label>

<label>Email: <input type="text" name="mc_EMAIL" value="" /></label>

<label>Website: <input type="text" name="mc_URL" value="" /></label>

<input type="submit" name="subscribe" value="Subscribe" />
</form>

<form class="mailchimp" method="post" action="[~[*id*]~]">
<label>First Name:</label><input type="text" name="mc_FNAME" value="" /><br />
<label>Last Name:</label> <input type="text" name="mc_LNAME" value="" /><br />
<label>Email: </label><input type="text" name="mc_EMAIL" value="" /><br />
<label>Website:</label> <input type="text" name="mc_URL" value="" /><br />
<input type="submit" name="subscribe" value="Subscribe" />
</form>

i can’t seem to find this form css class. is it inside the mailchimp?

Thanks

hey thanks but if I create the css that means i’ll just add it to the chunks?
is that right?
