Checkboxes on Form not aligned, despite applying CSS from previous support topics

I’ve read and applying the recommended CSS to the Additional CSS in Customise section of Wordpress (see beow):

imagel

My checkboxes on this page are still out of line: Fun & Learning | Educational Summer Camps for Kids (form is right at the bottom of the page).

Could someone assist with where I’m going wrong?

Hi Dominique. The checkboxes look aligned to me. Are you seeing something different, or am I looking in the wrong place?

It was corrected by one of our team. Something to do with a theme conflict!
