Pull Request Process

Describe the issue you are trying to resolve

This PR addresses six of 12 tasks in Issue 86 - (https://github.com/specollective/spec-frontend/issues/86) - am trying to merge in key changes as they are made.

Describe the changes you've made to resolve the issue

• Modifies the GetInvolved, ContactForm, and DonationTable components to address the following issues (taken verbatim from linked issue above)

• Use the contribution tiers as the primary image
• Remove learn more show more info interaction
• Link to documentation site (we can choose the specific page later)
• Body copy font is incorrect, should be Montserrat
• Donate button should open OC in a new window
• Contact Us button doesn't anchor to the Contact form at the bottom of the page

Add screenshots of the UI before and after your changes have been made

Before and After - cards

Before and After - contribution table

1) 2)

After:

Before and After - mobile (IPhone XR)

Additional Notes

• On the contribution table in GetInvolved.tsx, I will work to right align the ellipsis (...) on the next PR per Figma design.
• For mobile, I chose to keep the existing DonationImg image since that adding a contribution tier would have likely necessitated another card. If another card with the contribution tier is desired, perhaps that could be a future PR.
