最近想做一个前端登录页面，背景好看的，格式中规中矩的，这么难？我自己创一个吧！
效果图如下：
源码可以参考我的github，复制源码即可用：gym02/loginPage_Vue: 使用Vue+Axios搭建的动态登录网页，按钮和输入框渲染了动画，复制即可使用 (github.com)
(喜欢可以点个小星星start)评论区可以私我发这个mp4的背景图
html源码：

<script>new Vue({el:".login-box",data:{user:{username:'',password:''}},methods:{login(){axios.post("/user/login",this.user).then(resp =>{if(resp.data.code == 200){window.location.href = "http://localhost:8080/index.html";this.$message({message: '登陆成功',type: 'success'});}else{this.$message({message: '登陆失败',type: 'error'});}})}}})
</script></body>
</html>里面引入的各种css，js文件可以在上面我给出的github链接找到，复制下来。因为格式很大，这里不便分享。
需要背景图的可以评论区私我，有求必回！
