Some ideas to apply as base CSS rules for new projects.

base.css

html {
	box-sizing: border-box;
	cursor: default;
	font-family: system-ui, sans-serif;
	text-size-adjust: none;
	-webkit-tap-highlight-color: transparent;
}

*,
*::before,
*::after {
	box-sizing: inherit;
	position: relative;
}

/* Themed highlight color */
::selection {
	background-color: #0366d6;
	color: white;
}

code {
	cursor: text;
}

/* 
textarea and input[type="text"] already receive 
"cursor: text" via browsers' base stylesheets 
*/

a {
	cursor: pointer;
}

button[disabled], 
input[disabled] {
	cursor: default;
}
