How do you change the styling of a HubSpot pop up form?

I recently tried adding a HubSpot popup form but I noticed I didn’t like the styles. It wasn’t exactly what I was looking for. The form admin does not provide extensive customization options, but if you are comfortable adding CSS styles you can adjust the popup to fit your needs.

Below are the changes I wanted to make.

  • Larger featured image that could bleed off the bottom edge
  • Larger and colored title text to
  • Larger body text to increase readability
  • A button that looks less like a horizontal bar
  • White background instead of light gray to increase contrast
