Disallow shorthand properties that override related longhand properties.


a { background-repeat: repeat; background: green; }
/**                            ↑
 * This overrides the longhand property before it */

In almost every case, this is just an authorial oversight. For more about this behavior, see MDN's documentation of shorthand properties.

在几乎所有情况下,这只是作者个人的疏忽。关于这种情况的更多信息,请查看 MDN's documentation of shorthand properties



The following patterns are considered warnings:


a {
  padding-left: 10px;
  padding: 20px;
a {
  transition-property: opacity;
  transition: opacity 1s linear;
a {
  border-top-width: 1px;
  top: 0;
  bottom: 3px;
  border: 2px solid blue;

The following patterns are not considered warnings:


a { padding: 10px; padding-left: 20px; }
a { transition-property: opacity; } a { transition: opacity 1s linear; }
a { transition-property: opacity; -webkit-transition: opacity 1s linear; }
