sanitize.css
sanitize.css is a CSS library that provides consistent, cross-browser
default styling of HTML elements alongside useful defaults.
It is developed alongside normalize.css, which means every normalization
is included, and every normalization and opinion are clearly marked and
documented.

Features
Box sizing defaults to border-box
*, ::before, ::after {
box-sizing: border-box;
}
Backgrounds do not repeat by default
*, ::before, ::after {
background-repeat: no-repeat;
}
Pseudo-elements inherit text decoration and vertical alignment
::before,
::after {
text-decoration: inherit;
vertical-align: inherit;
}
Cursors only change to hint non-obvious interfaces
html {
cursor: default;
}
Text has a comfortable line height in all browsers
html {
line-height: 1.5;
}
Tabs appear the same on the web as in a typical editor
html {
tab-size: 4;
}
Words break to prevent overflow
html {
word-break: break-all;
}
Documents do not use a margin for outer padding
body {
margin: 0;
}
Navigation lists do not include a marker style
nav ol, nav ul {
list-style: none;
padding: 0;
}
Media elements align to the text center of other content
audio, canvas, iframe, img, svg, video {
vertical-align: middle;
}
SVGs fallback to the current text color
svg:not([fill]) {
fill: currentColor;
}
Tables do not include additional border spacing
table {
border-collapse: collapse;
}
Textareas only resize vertically by default
textarea {
resize: vertical;
}
Single taps are dispatched immediately on clickable elements
a, area, button, input, label, select, summary, textarea, [tabindex] {
-ms-touch-action: manipulation;
touch-action: manipulation;
}
ARIA roles include visual cursor hints
[aria-busy="true"] {
cursor: progress;
}
[aria-controls] {
cursor: pointer;
}
[aria-disabled="true"], [disabled] {
cursor: default;
}
Visually hidden content remains accessible
[aria-hidden="false"][hidden] {
display: initial;
}
[aria-hidden="false"][hidden]:not(:focus) {
clip: rect(0, 0, 0, 0);
position: absolute;
