Help with a custom "landing page" formatting

Site URL: https://www.thecarolamoon.com/must-have-brand-images-optin

Hello all,

I'm nearly done with my landing page: YAY!

Can you help me with a few niggling issues please?

• Despite having tried both "list-style-type: none;" and "list-style: none;" with and without "!important;", I still have double bullet points (normal and image style)
• I want to reduce the button margin (space above and below the button) to be reduced, but this code doesn't seem to be doing the trick:
  <style>.sqs-block-button .sqs-block-button-element--medium {
    padding:10px 25px !important;
    margin-top:-40px !important; 
    margin-bottom:-40px !important;
  }
  </style>
• SORTED, I'D LEFT A <FONT> TAG OPEN: (I need the list font/copy and the above line "Find out what brand photos will..." to be in black or #333333, but it seems to default to the site-wide colour settings...)
• Also, I'd love to reduce the space between the "Find out..." line and then the bulleted list below... 

Help please, and thank you in advance!

Phew, managed to sort the font colour issues, I'd left a <font> tag open 🤦‍♀️
