所以我试图理解为什么当我指定.thenav
类的宽度时,它不会扩展到页面的整个宽度。
我理解它正在考虑.container
类的特征,但我不明白为什么以及在指定宽度的情况下解决方案是什么?请帮助!
这是我正在发生的事情的图片(我附上了一张正在发生的事情的图片,因为jsfiddle让div出现在100%而且不是):
这是我的jsfiddle:

没有绝对定位并且宽度为100%的子div(如果它的显示是block
的默认值,则不需要)将被设置为它的容器宽度。您的div.container
设置为width
设置为1300像素,它是div.thenav
的父元素,因此div.thenav
的宽度也将是1300像素。
您可以删除容器上的宽度:
.container {
margin: 0px auto;
background-size: cover;
/*width: 1300px; remove this */
height: 100%;
}
或:
将div.thenav
移到div.container
之外,如下所示:
(https://jsfiddle.net/nod19rze/)
<div class="header">
<h1 id="box" onload="changed()"><image src="nbaone.png" width="40px" height="55px" class="nba">NBA Legends</h1>
<div class="thenav" onload="changed()">
<!-- contents of thenav here -->
</div>
<div class="container">
</div>
</div>

容器应该是第一个包装器,然后是标头,这可以解决问题。我不确定这是否是你需要的。请检查这个小提琴: https://jsfiddle.net/estgLn1q/1/
<div class="container">
<div class="header">
</div>
</div>
或者如果您想保持相同的html结构,请从&#39; .container&#39;中删除width:1300px
。这将导致容器采用与其父容器相同的宽度。

我只会将#box
和.thenav
移出.container
,然后在这些元素之后启动该类。
