Question

我的代码有一些小错误，看起来如何现在一切正常，但是当我进入手机屏幕调试并来到我的另一个div课程之前

On descktop everything alright i want to create menu like this

想要此“我的购物篮”和“个人资料” div出现在此图像之前....

这是我的代码：

Answer 1

如果要将“我的购物篮和个人资料”显示在前台，可以使用z-index属性设置优先级。签出https://www.w3schools.com/cssref/pr_pos_z-index.asp。通过将汉堡图像z-index设置为-1，该汉堡图像将出现在背景中，并且可以清晰地查看“我的购物篮和个人资料” div。

谢谢

Answer 2

我仍然使用z-index：999；关于我的购物篮和个人资料内容，但仍然存在相同的问题，我尝试添加z-index：-1;当我将z-index添加到div中时，将div的内容添加到汉堡，fried_dishes之类的div中，谢谢:)

我认为您的问题来自{ "name": "truffle-init-webpack", "version": "0.0.2", "description": "Frontend example using truffle v3", "scripts": { "lint": "eslint ./", "build": "webpack", "dev": "webpack-dev-server" }, "author": "Douglas von Kohorn", "license": "MIT", "devDependencies": { "babel-cli": "^6.22.2", "babel-core": "^6.22.1", "babel-eslint": "^6.1.2", "babel-loader": "^6.2.10", "babel-plugin-transform-runtime": "^6.22.0", "babel-preset-env": "^1.1.8", "babel-preset-es2015": "^6.22.0", "babel-register": "^6.22.0", "copy-webpack-plugin": "^4.0.1", "css-loader": "^0.26.1", "eslint": "^3.14.0", "eslint-config-standard": "^6.0.0", "eslint-plugin-babel": "^4.0.0", "eslint-plugin-mocha": "^4.8.0", "eslint-plugin-promise": "^3.0.0", "eslint-plugin-standard": "^2.0.0", "fs": "0.0.1-security", "html-webpack-plugin": "^2.28.0", "json-loader": "^0.5.4", "mongodb": "^3.1.4", "style-loader": "^0.13.1", "truffle-contract": "^1.1.11", "webpack": "^2.2.1", "webpack-dev-server": "^2.3.0" }, "dependencies": { "web3": "^0.20.2" } }类的z-index: -1

.pm_h_menu ul

请记住要检查CSS上的每个z-index，在这种情况下，您需要在标头上设置较高的z-index。

谢谢

Answer 4

嗨，我只是编辑我的CSS文件并删除少量代码并解决了这样的问题

/* 
| HEADER MENU | 
*/
.pm_h_menu ul {
    list-style-type: none;
    margin: 0;
    padding: 0;
    overflow: hidden;
    font-family: 'Montserrat', sans-serif;
    text-transform: uppercase;
    background-color: #333;
    letter-spacing: 1px;
    -webkit-transition: .3s;
    transition: .3s;
    z-index: -1;
}

至->

list-style-type: none;
overflow: hidden;
font-family: 'Montserrat', sans-serif;
text-transform: uppercase;
background-color: #333;
letter-spacing: 1px;
-webkit-transition: .3s;
transition: .3s;
z-index: 5;
position: fixed;
float:right;
right:0;
top:0;
margin:0;
padding:0;

和html

 <div class="pm_h_menu">
            <ul>
                <li><a href="./?p=pm_shop"><i class="fas fa-shopping-basket txt_color_pm"></i> <b>My Basket</b></a></li>
                <li><a href="./?p=profile"><i class="fas fa-user txt_color_pm"></i> <b>Profile</b></a></li>
            </ul>
        </div>
        <div class="pm_clear"></div>
