1、CSS用:focus伪类就能实现内部边框的颜色，边框颜色改为了红色。具体代码如下：<!DOCTYPE html><html><head><meta charset="UTF-8"><title>百度经验</title><style type="text/css">* {margin: 0; padding: 0;}.main {margin: 50px auto; width: 400px;}.inp {width: 200px;height: 30px;}.inp:focus {outline:none; border: 1px solid red;}</style></head><body><div class="main"><input type="text" class="inp"></div></body></html>
