In completing this challenge, I learned how to:

• add a box-shadow to a button, e.g.,

.payment-btn {
  box-shadow: 0 1rem 1rem $pale-blue;
}

• place elements on top of (or underneath) other elements using position: relatve and z-index, e.g.,

.payment-btn {
  position: relative;
  z-index: 1;
}

.cancel-btn {
  position: relative;
}

• name classes according to BEM (block, element, modifier) conventions

• There are some aspects of the BEM methodology such as redefinition levels and declarations that I didn't need to learn about for this project. However, I suspect that these ideas will come in handy for larger projects.

• To build this project, I used a very simple Makefile. I know that there are alternatives better suited to web development such as Gulp. I intend to learn how to use Gulp on a future project.

• mdn web docs: box-shadow - This is where I learned how to add a box-shadow to an element.

• Methodology/BEM - This is an excellent resource where you can learn about BEM class-naming conventions and file structure. Other BEM-related topics are covered as well.
