我是CSS的超级老兄,我已经制作了一些用于在页面上练习定位项目的方框。可悲的是,我已经遇到了问题!我想把盒子1和2放在一条线上,而盒子3和4放在下一行。我试图使用float: left
使方框2上升到方框1,但事情只是重叠。
**如果可以,会发布图片。

风格
* {
padding: 0;
margin: 0;
}
#box1 {
border: 1px solid black;
text-align: center;
height: 200px;
width: 400px;
margin: 1em;
line-height: 200px;
clear: left;
}
#box2 {
border: 1px solid black;
text-align: center;
height: 200px;
width: 400px;
margin: 1em;
line-height: 200px;
float: left;
}
#box3 {
border: 1px solid black;
text-align: center;
height: 200px;
width: 400px;
margin: 1em;
line-height: 200px;
}
#box4 {
border: 1px solid black;
text-align: center;
height: 200px;
width: 400px;
margin: 1em;
line-height: 200px;
}
我可以设法在第二行上使用float left属性排列第2,3和4行;但是,如果它不在所有三个盒子上,那么它们就会堆叠在一起。

将float: left
放在所有四个框上,并将clear: left
添加到第三个框:
* {
padding: 0;
margin: 0;
}
#box1 {
border: 1px solid black;
text-align: center;
height: 200px;
width: 200px;
margin: 1em;
line-height: 200px;
float: left;
}
#box2 {
border: 1px solid black;
text-align: center;
height: 200px;
width: 200px;
margin: 1em;
line-height: 200px;
float: left;
}
#box3 {
border: 1px solid black;
text-align: center;
height: 200px;
width: 200px;
margin: 1em;
line-height: 200px;
clear: left;
float: left;
}
#box4 {
border: 1px solid black;
text-align: center;
height: 200px;
width: 200px;
margin: 1em;
line-height: 200px;
float: left;
}

<div id="box1">
<h1>Box One</h1>
</div>
<div id="box2">
<h1>Box Two</h1>
</div>
<div id="box3">
<h1>Box Three</h1>
</div>
<div id="box4">

这基本上是解决这个问题的理念。最好的方法是在wrap
div
每组方框
* {
padding: 0;
margin: 0;
}
.boxes {
width: auto;
height: 100px;
}
#box1 {
border: 1px solid black;
text-align: center;
height: 50px;
width: 50px;
margin: 1em;
font-size: 12px;
line-height: 50px;
float: left;
}
#box2 {
border: 1px solid black;
text-align: center;
height: 50px;
width: 50px;
font-size: 12px;
margin: 1em;
line-height: 50px;
float: left;
}
#box3 {
border: 1px solid black;
text-align: center;
height: 50px;
width: 50px;
font-size: 12px;
margin: 1em;
line-height: 50px;
float: left;
}
#box4 {
border: 1px solid black;
text-align: center;
height: 50px;
font-size: 12px;
width: 50px;
margin: 1em;
line-height: 50px;
float:left;
}
