[英]Why is @media overridden even though my max-height is 768px and not 1280px?
[英]@media screen and (min-width: 1280px){ does not work even though my resolution is 1920*1080
1920 * 1080 不显示导航菜单项
我为除 >1280 之外的所有设备宽度设置 display = none
`@media only screen and (min-width: 100px) and (max-width: 260px) {
header .navigation {
display: none;
}
@media only screen and (min-width: 260px) and (max-width: 350px) {
header .navigation {
display: none;
}
@media only screen and (min-width: 370px) and (max-width: 500px) {
header .navigation {
display: none;
}
@media only screen and (min-width: 500px) and (max-width: 1280px) {
header .navigation {
display: none;
}
@media only screen and (min-width: 350px) and (max-width: 370px) {
header .navigation {
display: none;
}
@media screen and (min-width: 1280px){
header .navigation{
height:3em;
position: relative;
background: dark orange ;
width:98em;
top:50;
left:-12em;
font-size:30px;
font-color: dark orange;
font-family: Meow Script;
padding:20px;
}
header .navigation .navigation-items a{
font-family: Meow Script;
position: relative;
background: dark red;
color: white;
font-size: 3em;
font-weight: 500;
width:100px;
font-size:20px;
text-decoration: none;
margin-left: 15px;
transition: 0.3s ease;
left :15em;
padding: 15px 40px;
border-radius:150px;
font-family: Meow Script;
}
header .navigation .navigation-items a span{
border-radius:50px;
width:100px;
font-family: Meow Script;
font-size: 1.2em;
}
header .navigation .navigation-items a:before{
content: '';
position: absolute;
font-family: Meow Script;
width: 0;
height: 3px;
bottom: 0;
left: 0;
transition: 0.3s ease;
}
header .navigation .navigation-items a:hover:before{
width: 100%;
}
}`
if I use the same in a different CSS file without media queries I am able to see the navigation menus in my Laptop 1920* 1080 resolution.
在没有媒体查询的情况下使用 CSS 时显示的导航菜单。 当 CSS 与 1920*1080 笔记本电脑的媒体查询一起使用时,导航菜单不显示
我尝试编写媒体查询,使导航菜单仅显示 >1280 像素的宽度,而不显示较小的屏幕宽度,如移动设备和笔记本电脑。
我为所有设备宽度 <1280px 设置了 display = none。
但是导航菜单不显示 1920*1080 为
很好(>1280px 宽度)
您only
在最后一个mediaQuery
上缺少一个。
@media screen and (min-width: 1280px){
应该
@media only screen and (min-width: 1280px){
开始修复您的 CSS 中的一些错误,如果您不知道如何修复,请尝试使用在线验证器,如下所示:

也许问题不在媒体查询上,而在其他规则生成的 output 上。
关于媒体查询的提示:将所有 CSS 放在媒体查询之外,仅使用它们来更改所需的功能。 注意媒体查询的顺序,有时一条语句会覆盖之前的语句。
试试这个 CSS:
header .navigation {
display: none;
}
header .navigation {
height: 3em;
position: relative;
background: darkorange;
width: 98em;
/* top:50;*/ /* this make the object disappear */
/* left:-12em;*/ /* this make youtr object disappear */
font-size: 30px;
color: #000;
font-family: Meow Script;
padding: 20px;
}
header .navigation .navigation-items a {
font-family: Meow Script;
position: relative;
background: darkred;
color: white;
font-size: 3em;
font-weight: 500;
width: 100px;
font-size: 20px;
text-decoration: none;
margin-left: 15px;
transition: 0.3s ease;
left : 15em;
padding: 15px 40px;
border-radius: 150px;
font-family: Meow Script;
}
header .navigation .navigation-items a span {
border-radius: 50px;
width: 100px;
font-family: Meow Script;
font-size: 1.2em;
}
header .navigation .navigation-items a:before {
content: '';
position: absolute;
font-family: Meow Script;
width: 0;
height: 3px;
bottom: 0;
left: 0;
transition: 0.3s ease;
}
header .navigation .navigation-items a:hover:before {
width: 100%;
}
@media screen and (min-width: 1280px) {
header .navigation {
display: block;
}
}
