The Gravity Forms preview does not show the SUBMIT button while the front end which I styled with MT does show. So I am confident on telling you that I did something wrong with MT on styling the form. Now if I select display: none the button completely disappear which I don’t want. I only want the button to appear on selection one of the option. If I delete the value “block” from “display” the button show as desired but is not centred… getting mad…
I recommend clearing the field where you set display: block (rather than setting display:none, as this will override gravity forms when it tries to show the button).
Regarding centring the button, perhaps you could target the container element for the button (.gform_footer) then set text-align: center?
Inline elements will be centred if the parent element has text-align:center. Block elements do not, but can be centred by setting left and right margins on the block element to auto.
