How to remove shadow & rollover border on uploaded submit button image?

I want to use a custom graphic for this submit button – and uploaded a JPG, but it has a drop shadow and a rollover border that I'd like to be removed as it doesn't look good with the button. Can I do this with CSS? I don't mind if it moves down and over a notch, I just don't want the dropshadow and the rollover blue border. 

This button is on this form:

Thanks!

Please try injecting the following CSS code to the form to remove the background and shadows for the Submit button.

.form-submit-button {

box-shadow: none !important;

-webkit-box-shadow: none !important;

-webkit-border-radius: none !important;

border-radius: none !important;

background: none !important;

}

.form-submit-button-blue:hover {

  border: none !important;

}

Hope this information helps! 

Thanks! That removed the drop shadow on the regular instance of it, but it still shows a blue border upon rollover, any way to remove that?

Could you try changing the Button style to default button style from the Submit button properties?

I selected the first button Style, and that removed the blue border rollover, thanks!
