推荐答案
我相信你正在寻找大纲 CSS属性psuedo属性）：
I believe you are looking for the outline CSS property (in conjunction with active and hover psuedo attributes):
/* turn it off completely */
select:active, select:hover {
outline: none
}
/* make it red instead (with with same width and style) */
select:active, select:hover {
outline-color: red
}
style和outline-width
