Form not Aligning Properly

The Gravity Forms CSS isn't being output on the page so the form isn't being styled at all.

This is either because CSS output is turned off on the Gravity Forms page Settings or more likely your theme lacks the necessary wp_head() function call in your header.php file and the wp_footer() function call in your footer.php file.

Make sure your header.php and footer.php file have these function calls in place.

wp_head() documentation can be found here:

wp_footer() documentation can be found here:

How are you displaying the form on that page?

Are you using the function call or the shortcode?

If you are using the shortcode is that page content being called directly or does it contain a WordPress loop?

Let me know, this determines the next step because in certain cases the scripts need to manually be enqueued if used outside the standard shortcode in a loop display method.

It's getting the submit style buttons from your theme. If you want to change the button style you can add some custom CSS to your themes CSS to style that element.

You would target it by adding this CSS to your themes stylesheet:

body .gform_wrapper .gform_footer input[type=submit] {YOUR CSS GOES HERE}

You would add whatever CSS you want to style the button to your liking.

It looks the way it does right now because of styles being applied by your theme due to CSS inheritance.
