/* Global Remedies
******************/

/* Use border-box by default, globally */
*, ::before, ::after { box-sizing: border-box; }

/*
* Consistent line spacing...
* CSS Inline Layout Module Level 3: https://drafts.csswg.org/css-inline-3/#line-sizing-property
*/
html { line-sizing: normal; }

/* Remove the tiny space around the edge of the page */
body { margin: 0; }


/* Headings
***********/

/* Switch to rem units for headings */
/* @@@ Initial values are based on existing browser defaults */
h1 { font-size: 2rem; }
h2 { font-size: 1.5rem; }
h3 { font-size: 1.17rem; }
h4 { font-size: 1.00rem; }
h5 { font-size: 0.83rem; }
h6 { font-size: 0.67rem; }

/* Keep h1 margins consistent, even when nested */
h1 { margin: 0.67em 0; }


/* Typography
*************/

/* Overflow by default is bad */
pre { white-space: pre-wrap; }

/*
* 1. Solid, thin horizontal rules
* 2. Remove Firefox `color: gray`
* 3. Remove default `1px` height, and common `overflow: hidden`
*/

  border-style: solid;
  border-width: 1px 0 0;
  color: inherit;
  height: 0;
  overflow: visible;
}


/* Embedded Elements
********************/

/*
* 1. Block display is usually what we want
* 2. Remove strange space-below when inline
* 3. Responsive by default
*/
img, svg, video, canvas, audio, iframe, embed, object {
  display: block;
  vertical-align: middle;
  max-width: 100%;
}

/*
* Maintain intrinsic aspect ratios when `max-width` is applied
* (iframe, embed, and object have no intrinsic ratio, set height explicitly)
*/
img, svg, video, canvas {
  height: auto;
}

/*
* There is no good reason elements default to 300px,
* and audio files are unlikely to come with a width attribute
*/
audio { width: 100%; }


/* Old Browsers
***************/

/* Remove the border on images inside links in IE 10 and earlier */

/* Hide the overflow in IE 10 and earlier */
svg { overflow: hidden; }

/* Default block display on HTML5 elements */

* 2. Remove the padding in IE 10
