박스사이징이란?
세 개의 떠 있는 상자를 나란히 쉽게 만들 수 있습니다. 그러나 각 상자의 너비를 늘리는 항목(예: 패딩 또는 테두리)을 추가하면 상자가 깨집니다. 이 box-sizing속성을 사용하면 상자의 전체 너비(및 높이)에 패딩과 테두리를 포함할 수 있으므로 패딩이 상자 내부에 유지되고 깨지지 않습니다.
CSS Box Sizing 장 에서 box-sizing 속성에 대해 자세히 읽을 수 있습니다 .
이미지 나란히
상자 격자를 사용하여 이미지를 나란히 표시할 수도 있습니다.
예시
.img-container {
float: left;
width: 33.33%; /* three
containers (use 25% for four, and 50% for two, etc) */
padding:
5px; /* if you want space between the images */
}
동일한 높이 상자
In the previous example, you learned how to float boxes side by side with an equal width. However, it is not easy to create floating boxes with equal heights. A quick fix however, is to set a fixed height, like in the example below:
Box 1
Some content, some content, some content
Box 2
Some content, some content, some content
Some content, some content, some content
Some content, some content, some content
Example
.box {
height: 500px;
}
However, this is not very flexible. It is ok if you can guarantee that the boxes will always have the same amount of content in them. But many times, the content is not the same. If you try the example above on a mobile phone, you will see that the second box's content will be displayed outside of the box. This is where CSS3 Flexbox comes in handy - as it can automatically stretch boxes to be as long as the longest box:

You can also use float with a list of hyperlinks to create a horizontal menu:

Web Layout Example
It is also common to do entire web layouts using the float property:
Example
.header, .footer {
background-color: grey;
color: white;
padding: 15px;
}
.column {
float: left;
padding: 15px;
}
.clearfix::after {
content:
"";
clear: both;
display: table;
}
.menu {
width: 25%;
}
.content {
width: 75%;
}
