What is `CSS`

Strategies

Rely on constant values like px when defining should-be-constant or calculated elements.

Flexbox is for spreading elements out into one direction (and they might wrap onto the next line).

Grid is for positioning elements into a specific grid, so two dimensions (X and Y).

Position relative or absolute allows you to force an element to change its position regardless of the flow of components around it.

Suppress visited link color change:

a, a:visited, a:hover, a:active {
  color: inherit;
}

Adjust Border Radius (how curved are the border corners):

borderRadius: "10px"

/* firefox */
details > summary:first-of-type {
  list-style-type: none;
}

/* chrome */
::-webkit-details-marker {
  display:none;
}
