// Body
//
// 1. Remove the margin in all browsers.
// 2. As a best practice, apply a default `background-color`.
// 3. Prevent adjustments of font size after orientation changes in IE on Windows Phone and in iOS.
// 4. Change the default tap highlight to be completely transparent in iOS.

  margin: 0; // 1

// Future-proof rule: in browsers that support :focus-visible, suppress the focus outline
// on elements that programmatically receive focus but wouldn't normally show a visible
// focus outline. In general, this would mean that the outline is only applied if the
// interaction that led to the element receiving programmatic focus was a keyboard interaction,
// or the browser has somehow determined that the user is primarily a keyboard user and/or
// wants focus outlines to always be presented.
//
// See https://developer.mozilla.org/en-US/docs/Web/CSS/:focus-visible
// and https://developer.paciellogroup.com/blog/2018/03/focus-visible-and-backwards-compatibility/

// Content grouping
//
// 1. Reset Firefox's gray color
// 2. Set correct height and prevent the `size` attribute to make the `hr` look like an input field
//    See https://www.w3schools.com/tags/tryit.asp?filename=tryhtml_hr_size

hr {
  margin: $hr-margin-y 0;
  color: $hr-color; // 1
  background-color: currentColor;
  border: 0;
  opacity: $hr-opacity;
}

hr:not([size]) {
  height: $hr-height; // 2
}


// Typography
//
// 1. Remove top margins from headings
//    By default, `<h1>`-`<h6>` all receive top and bottom margins. We nuke the top
//    margin for easier control within type scales as it avoids margin collapsing.

%heading {
  margin-top: 0; // 1
  margin-bottom: $headings-margin-bottom;

  font-style: $headings-font-style;
