#left {
    position: fixed;
    left: 0;
    top: 0;
    height: 100vh;
    width: 300px;
    /* background: blue; *//* 解开此处注释来查看效果 */
}

#right {
    position: fixed;
    left: 300px;
    top: 0;
    height: 100vh;
    width: calc(100vw - 300px); 
    /* 如果浏览器不支持CSS3 calc方法，可以使用js计算宽度 */
    /* background: red; *//* 解开此处注释来查看效果 */
