Enhance HubSpot form errors

Created by: st0nebraker

Marketing would like form submission errors to be hidden. To let the fields themselves display the error, for a sleeker UX.

We cannot override HubSpot forms in our repo since they are iframes from an external domain. (ref)

In HubSpot find the global stylesheet and add the following CSS. Take care and edit with caution as there is no version control with these edits.

.hs_error_rollup {
display: none;
}

HubSpot dox on styling their forms.
