在響應式網站布局中刪除導航欄
[英]Removing navigation bar in responsive website layout
問題描述
我正在嘗試為我的網站刪除移動網站上的導航欄。 但是， display: none; 似乎沒有做任何事情。 我不確定我使用的 javascript 是否會影響這一點，因為我無法阻止 javascript 在屏幕寬度斷點處運行。 要刪除 javaScript 中的元素，我嘗試使用screen.width
我已鏈接以下代碼：
// When the user scrolls down 50px from the top of the document, resize the header's font size window.onscroll = function() {scrollFunction()}; function scrollFunction() { if (document.body.scrollTop > 30 || document.documentElement.scrollTop > 30) { document.getElementById("navbar").style.fontSize = "30px"; document.getElementById("logo").style.width = "100px"; document.getElementById("nav").style.paddingTop = "20px"; } else { document.getElementById("navbar").style.fontSize = "90px"; document.getElementById("logo").style.width = "200px"; document.getElementById("nav").style.paddingTop = "100px"; document.getElementById("navbar").style.backgroundColor = 'green' ; } }

您的 HTML 結構不在<body>標簽之間。 #navbar 上也缺少一個“}”。
/*for Desktop*/
@media only screen and (min-width: 600px) {
...
#navbar {
background-color: white;
...
transition: 1s ease-in-out;
} <- missing
}

' @media screen and (min-width: 600px)內的所有嵌套 css @media screen and (min-width: 600px)只會在width < 600px觸發。 這就是使您的另一個媒體查詢（ @media only screen and (max-width: 600px)嵌套在其中的原因）永遠不會觸發。
移動優先設計是我認為解決這個問題最簡單的方法。
CSS代碼：
li a {
color: black;
}
li a:visited {
color: black;
}
li a:hover {
color: #cebea1;
}
#navbar {
display: none;
}
#navSpace {
margin-top: 0px;
content: "";
}
.mobileNav li {
float: left;
}
.mobileNav li a {
padding: 20px 30px;
}
.mobileNav .menu {
clear: none;
float: right;
max-height: none;
}
.mobileNav .menu-icon {
display: none;
}
@media only screen and (min-width: 600px) {
.mobileNav {
display: none;
}
#navbar {
background-color: white;
padding-top: 25px;
color: black;
text-align: center;
font-size: 90px;
font-weight: bold;
position: fixed;
top: 0;
left: 0;
width: 100%;
transition: 1s ease-in-out;
display: block;
}
.nav {
font-size: 20px;
border-width: 1px 0;
list-style: none;
margin: 0;
text-align: center;
}
.nav li {
display: inline;
}
.nav a {
display: inline-block;
padding: 10px;
padding-right: 20px;
padding-top: 45px;
text-decoration: none;
font-size: 15px;
font-family: "Quicksand", sans-serif;
}
#logo {
padding-left: 10px;
height: auto;
width: 200px;
transition: 1s ease-in-out;
}
#navSpace {
margin-top: 260px;
content: ".";
visibility: hidden;
}
}
