所以我有一个简单的两个DIV窗格的网站:一个内容区域和一个固定的300px菜单,两者最多都是1200px。我希望用户能够调整窗口大小并使LEFT窗格缩小,同时保持固定的正确菜单。但是现在我找不到任何方法来做到这一点,一切看起来都很好,但是如果我调整窗口大小,左侧窗格不会缩小,而右侧菜单只是包裹在屏幕的底部。使用左侧菜单可以轻松实现,但菜单位于右侧。以下是我到目前为止的情况:
#main
{
max-width: 1200px;
margin-right: auto;
margin-left: auto;
margin-top: 0;
display: block;
padding: 0;
}
#left
{
max-width: 890px;
float: left;
padding-right: 10px;
}
#right
{
width: 290px;
top: 0;
float: right;
padding-right: 10px;
padding-left: 10px;
}

您可以使用CSS calc()
来调整左侧容器的宽度。
<强> HTML 强>
<div id="main">
<div id="left"></div>
<div id="right"></div>
</div>
<强> CSS 强>
#main{
width: 100%; //set to 100% since you're capping it at 1200 anyways
max-width: 1200px;
/* margin-right: auto;
margin-left: auto;
margin-top: 0; */ condense these to the following:
margin: 0 auto;
/*display: block;*/ already a block element so not necessary
padding: 0;
overflow: hidden; //add to correct floating elements
}
#left{
background: red; //just for my test
height: 100px; //just for my test
width: calc(100% - 300px); //readjusts based on screen size
float: left;
padding-right: 10px;
-moz-box-sizing: border-box; //if you use padding add these lines to fix issue of padding adding to width
-webkit-box-sizing: border-box;
box-sizing: border-box;
}
#right{
background: black; //just for my test
height: 100px; //just for my test
width: 300px;
/*top: 0;*/ //dont need, not doing anything
float: right;
/*padding-right: 10px;
padding-left: 10px;*/ //can condense to following:
padding: 0 10px;
-moz-box-sizing: border-box; //see padding explanation above
-webkit-box-sizing: border-box;
box-sizing: border-box;
}
如果您担心旧浏览器,可以使用display: table
和display: table-cell
执行此操作,如下所示:
<强> CSS 强>
#main{
width: 100%;
max-width: 1200px;
margin: 0 auto;
display: block;
padding: 0;
display: table; //add
table-layout: fixed; //add
}
#left{
display: table-cell; //use instead of float
background: red;
height: 100px;
padding-right: 10px;
-moz-box-sizing: border-box;
-webkit-box-sizing: border-box;
box-sizing: border-box;
}
#right{
display: table-cell; //use instead of float
background: black;
height: 100px;
width: 300px;
padding: 0 10px;
-moz-box-sizing: border-box;
-webkit-box-sizing: border-box;
box-sizing: border-box;
}

而不是浮动div,请尝试左右窗格中的display: inline-block
,或CSS3 flexbox(取决于您支持旧版浏览器的距离)。
