As with most shorthand properties, you don’t need to specify all the properties listed, but any omitted properties will
revert to their default values. In the ca of border-style, if you omit a value no border will show at all, becau the default value is none. A border will only be visible as long as the border-style property has been t to something other than none or hidden, or has been restated explicitly after the initial shorthand declaration. Otherwi, no border will show and the border-width will be ret to zero. Therefore, its good practice to specify a value for the border’s style when you’re using shorthand notation.
与⼤多数速记属性⼀样，您⽆需指定所有列出的属性，但是任何省略的属性都将恢复为其默认值。 在border-style的情况下，如果省略⼀个值，则根本不会显⽰任何边框，因为默认值为none 。 仅当border-style属性设置为none或hidden以外的其他值，或者在初始速记声明后已明确地重新设置边框时，边框才可见。 否则，将不会显⽰任何边框，并且border-width将重置为零。 因此，在使⽤速记符号时，最好为边框的样式指定⼀个值。
