When I add a form to my landing page the Submit and Clear buttons look correct when I'm working in the Design Studio editor, but when I preview or approve the landing page, the Clear button moves to a different line.
In your landing page template there are two sections for "fancy button". Since most customers choose not to display the "Clear" button, having both fancy button sections does not affect a form's appearance on the landing page. If you want to display both the "Submit" and the "Clear" buttons on your landing page on the same line, the you'll need to remove code from your landing page template.
Steps to edit the landing page template
1. Choose your landing page template in the Design Studio
2. Click Edit Draft
3. Click HTML Source
4. Scroll until you find "<!-- Jquery for fancy things!-->"
5. Highlight and remove the following text from the template
// to make fancy buttons. Uses noConflict just in case
var $jQ = jQuery.noConflict();
// Use jQuery via $j(...)
6. Click Save and Close
7. Click Template Actions
8. Click Approve
This change will affect all of the landing pages that use this template, so you'll need to be consistent with how you display the "Clear" button. After approving the landing page template you'll need to re-approve all of the landing pages that use this landing page template.
