Replacing submit button with custom animated link?

Hi! We use animated links through a plug-in (seen here) and I want to make sure my submit buttons match these same links, but I can’t work out how to do this. It looks to require more CSS knowledge than I currently have. Can anyone tell me what CSS I might need to do this? I know the CSS class for the link, (I used the Inspect tool to find out and it appears to be ‘ue-link’) but can’t work out how to replace the GF buttons with that link style.
