##General Advice

- set the boxsizing property on the _, _::after, and \*::before. Then use the body tag to flow inheritance down to all elements.

```scss
*,
*::before,
*::after {
  margin: 0;
  padding: 0;
  box-sizing: inherit;
}

body {
  font-family: Arial, Helvetica, sans-serif;
  font-size: 1.6rem;
  color: #777;
  padding: 3rem;
  line-height: 1.7;
  box-sizing: border-box;
}
```

- Use rem units where ever you would use a px unit. Set the rem on html as a percentage to allow user styles to override yours, but keep the default a multiple of 10. Since most browsers are 16px default for rem 10/16 = 62.25%.

```scss
html {
  // Set's the rem to 10px in most browsers (16px)
  font-size: 62.5%;
}
```
