Question

因此经过几天的研究和干预后，我似乎无法理解这个概念。

我想要完成的是在页面顶部有一个导航栏，其中包含三个组件：

顶部导航栏左侧的图像（Logo1）。
导航栏中央的图像（Logo2）。
..最后，在右边的一个汉堡包菜单，用不透明度向下滑动整个页面，并且链接项目以浏览网站。

以下是我试图展示所有这些

的方法

＆＃13;

function openNav() {
document.getElementById("myNav").style.height = "100%";
}

function closeNav() {
document.getElementById("myNav").style.height = "0%";
}

＆＃13;

li{
                text-decoration: none;
            }
            .overlay {
                        height: 0%;
                        width: 100%;
                        position: fixed;
                        z-index: 1;
                        top: 0;
                        left: 0;
                        background-color: rgb(0,0,0);
                        background-color: rgba(0,0,0, 0.9);
                        overflow-y: hidden;
                        transition: 0.5s;
                    }

                    .overlay-content {
                    position: relative;

                    text-align: center;
                    margin-top: 0px;
                }

                .overlay a {
                    padding: 8px;
                    text-decoration: none;
                    font-size: 36px;

                    display: block;
                    transition: 0.3s;
                }

                .overlay a:hover, .overlay a:focus {
                    color: #f1f1f1;
                }

                    font-size: 60px;
                }

                header{

                background:#1d1f20; 
                height:60px; 
                line-height:60px;
                }

                @media screen and (max-height: 450px) {
                    .overlay {overflow-y: auto;}
                    .overlay a {font-size: 20px}
                    .overlay .closebtn {
                    font-size: 80%;
                    top: 15px;
                    right: 35px;

非常感谢任何帮助或指导。我还在学习！ :)谢谢！

Answer 1

你的汉堡图标浮动到左边。只需将其更改为float：right;

function openNav() {
document.getElementById("myNav").style.height = "100%";
}

function closeNav() {
document.getElementById("myNav").style.height = "0%";
}

 

span{
   float: right !important;
   color: white;
 }
li{
                text-decoration: none;
            }
            .overlay {
                        height: 0%;
                        width: 100%;
                        position: fixed;
                        z-index: 1;
                        top: 0;
                        left: 0;
                        background-color: rgb(0,0,0);
                        background-color: rgba(0,0,0, 0.9);
                        overflow-y: hidden;
