我想制作我的ul
height
变量,因此当width
和600px
之间的768px
屏幕有height
时(例如ul
),例如390px
,以及height
介于768
和900
之间的另一个height
( ul
)420px
,如此等等。
我不明白为什么我的媒体查询无效。
以下是代码:
HTML:
<div id="meniu">
<div id="cat" >
<div class="catico">
<img src="img/Categories.png"/>
</div>
<div class="cattext">
Categories:
</div>
</div>
<ul>
<li><div class="cerculet"></div><a href="#" class="dece">All categories </a> </li>
<li><div class="cerculet"></div><a href="#" class="dece">Everything </a> </li>
<li><div class="cerculet"></div><a href="#" class="dece">Nature </a> </li>
<li><div class="cerculet"></div><a href="#" class="dece">Animals </a> </li>
<li><div class="cerculet"></div><a href="#" class="dece">popular </a> </li>
<li><div class="cerculet"></div><a href="#" class="dece">Traveling </a> </li>
<li><div class="cerculet"></div><a href="#" class="dece">Companies </a> </li>
<li><div class="cerculet"></div><a href="#" class="dece">Sports</a> </li>
<li><div class="cerculet"></div><a href="#" class="dece">Food</a> </li>
<li><div class="cerculet"></div><a href="#" class="dece">Restaurants</a> </li>

<li><div class="cerculet"></div><a href="#" class="dece">Business</a> </li>
<li><div class="cerculet"></div><a href="#" class="dece">Technology</a> </li>
<li><div class="cerculet"></div><a href="#" class="dece">Music</a> </li>
<li><div class="cerculet"></div><a href="#" class="dece">Art</a> </li>

<li><div class="cerculet"></div><a href="#" class="dece">Films</a> </li>
<li><div class="cerculet"></div><a href="#" class="dece">Books</a> </li>
<li><div class="cerculet"></div><a href="#" class="dece">Products</a> </li>
</ul>
</div>
这是 CSS :

答案 0 :(得分:3)
您需要切换查询的顺序,因为您使用的是非移动优先方法,这意味着最后一个查询将覆盖第一个查询。
另外,您正在其中一个查询中查看px
,需要在and
之间留出空格
所以这个:
@media screen and(max-height:767px){
#meniu ul{
height:390px;
}
}
@media (min-height:768px) and (max-height:899){
#meniu ul{
height:450px;
}
}
应该是这样的:
@media (min-height:768px) and (max-height:899px){
#meniu ul{
height:390px;
}
}
@media screen and (max-height:767px) {
#meniu ul{
height:450px;
}
}

你可以试试这个:
@media only screen and (max-device-width: 899px) and (min-device-width: 768px)
{
ul
{
height: 390px;
}
}
@media only screen and (max-device-height: 760px) and (min-device-height: 600px)
{
ul
{
height: 420px;
}
}

确保将以下元标记添加到<head>
部分
<meta name="viewport" content="width=device-width, initial-scale=1">
这对于使用@media
查询
