// 1. Remove the margin in all browsers.

// 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.

// Avoid 300ms click delay on touch devices that support the `touch-action` CSS property.
//
// In particular, unlike most other browsers, IE11+Edge on Windows 10 on touch devices and IE Mobile 10-11
// DON'T remove the click delay when `<meta name="viewport" content="width=device-width">` is present.
// However, they DO support removing the click delay via `touch-action: manipulation`.

// 1. Browsers set a default `min-width: min-content;` on fieldsets,
//    unlike e.g. `<div>`s, which have `min-width: 0;` by default.
//    So we reset that to ensure fieldsets behave more like a standard block element.
//    See https://github.com/twbs/bootstrap/issues/12359
//    and https://html.spec.whatwg.org/multipage/#the-fieldset-and-legend-elements
