58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}

By changing:

test, err := time.Parse("10/15/1983", "10/15/1983")

Go has excellent build tools that mitigate the need for using make. For example, go install won't update the target unless it's older than the source files.

However, a Makefile can be convenient for wrapping Go commands with specific build targets that simplify usage on the command line. Since most of the targets are "phony", it's up to you to weigh the pros and cons of having a dependency on make versus using a shell script. For the simplicity of being able to specify targets that can be chained and can take advantage of make's chained targets,

Snippet development
Quickly finding snippets

There are some ways you can quickly find a snippet file:

    *

      M-x yas/new-snippet

      Prompts you for a snippet name, then tries to guess a suitable directory to store it, prompting you for creation if it does not exist. Finally, places you in a new buffer set to snippet-mode so you can write your snippet.
