I'm noticing that search forms created in Weblink Designer allow for CSS classes to be applied to form elements. However, I'm not finding any guidance in the Laserfiche Weblink documentation as to where the CSS definitions should go.

I'm seeing "WebLink\Web Files\Custom\CustomWebLinkStyles.css" in the site but I need to confirm that if I put the custom CSS in that file, it's not going to be overwritten or altered.
