我有一个导航菜单,可以调整特定窗口大小的大小。工作得很好,但我有一个问题,导航列表居中在它的父div,但同一div中的徽标没有。以下是代码:
HTML
<nav id="top_menu">
<div id="logo"> <img src="images/logo.svg"> </div>
<ul class="navigation">
<li data-slide="1">Home</li>
<li data-slide="2">Skills</li>
<li data-slide="3">Over mij</li>
<li data-slide="4">Portfolio</li>
<li data-slide="5">Contact</li>
</ul>
</nav>
CSS(Sass with Bourbon mixins)
// NAVIGATION
#top_menu {
@include display(flex);
@include flex-flow(row wrap);
@include justify-content(flex-start);
@include align-content(center);
position: fixed;
width: 100%;
top: 48px;
left: 0;
background-color: white;
height: 80px;
z-index: 1;
@media screen and (max-width:960px) {
height: 60px;
top: 36px;
}
@media screen and (max-width:640px) {
top: 0;
height: auto;
@include flex-flow(column wrap);
@include justify-content(center);
@include align-content(center);
}
}
#logo {
display: block;
margin-left: 3%;
width: 12%;
max-width: 150px;
min-width: 100px;
@media screen and (max-width:640px) {
margin: 0;
width: 100%;
}
img {
position: relative;
width: 100%;
max-width: 150px;
min-width: 100px;
}
}
.navigation{
width: 82%;
list-style: none;
margin: 0;
@include display(flex);
@include flex-flow(row wrap);
@include justify-content(flex-start);
@include align-content(center);
//@media all and (max-width:800px) {
// @include justify-content(space-around);
//}
@media all and (max-width:960px) {
width: 75%;
@include justify-content(space-around);
}
@media all and (max-width:640px) {
width: auto;
@include flex-flow(column wrap);
padding: 0;
}
li {
color: black;
text-decoration: none;
display: block;
margin: 0 20px 0 20px;
padding: 10px;
font-family: 'PT Sans', sans-serif;
font-size: 20px;
text-transform: uppercase;
line-height: 40px;
@media all and (max-width:960px) {
margin: 0;
font-size: 18px;
line-height: 30px;
}
@media all and (max-width:640px) {
text-align: center;
padding: 10px;
}
&:hover,&.active {
box-shadow: 0px 10px 0px 0px rgba(245, 86, 78, 1);
color: #333;
font-weight: bold;
cursor:pointer;
@media screen and (max-width: 960px) {
box-shadow: 0px 6px 0px 0px rgba(245, 86, 78, 1);
}
}
}
}
到目前为止我发现的是它并没有真正把两个div放在彼此之下;将导航的宽度更改为更低或更高的位置会更改徽标的位置。然而,我无法找到如何解决这个问题,并将徽标粘贴在导航上方的中心位置。我喜欢弹性盒子,但有时候有点难以理解。我在这里做错了什么?

问题是当您需要使用align-items时,您正在使用align-content属性。 Align-items用于控制项目在同一行上的对齐方式。 Align-content用于控制行相对于其他行的对齐方式。

.navigation{
width: 82%;
list-style: none;
margin: 0;
border: 1px solid;
@include display-flex;
@include flex-flow(row wrap);
@include justify-content(flex-start);
@include align-items(center);
}

flex-box
很安静但不是那么坚固,我会使用来自IE8的display:table
。
这是一个例子,修改了图像和li字体大小的行为。

#top_menu {
display:table;
width:100%;
text-align:center;
background:gray linear-gradient(to bottom, #555 , #eee);
padding:5px;
box-shadow:0 0 5px;
}
#logo , .navigation{
display:table-cell;
vertical-align:middle;
margin:0;
padding:0;
text-align:justify;
font-size: 20px;
line-height:0;
width:18%;
}
.navigation {
width:82%;
}
.navigation li {
display:inline-block;
color: black;
text-decoration: none;
margin: 0 20px 0 20px;
padding: 10px;
font-family: 'PT Sans', sans-serif;
font-size: 1em;
text-transform: uppercase;
line-height: 2em;
}
.navigation:after {
content:'';
display:inline-block;
width:100%;
vertical-align:top;
}
img {
width:100%;
min-height:100px;
max-height:250px;;
max-width: 250px;
min-width: 100px;
vertical-align:top;
display:block;
margin: 2px auto;
}
@media all and (max-width:960px) {
#logo , .navigation
{
display:block;
font-size:0.8em;
width:100%;
}
#logo img {
width:100px;}
}
更新代码以调整图像大小,直到菜单下拉
