CSS基礎篇--CSS3之多列布局columns詳解

columns語法：columns：[ column-width ] || [ column-count ]

設置或檢索對象的列數和每列的寬度:

• [ column-width ]：設置或檢索對象每列的寬度；
• [ column-count ]：設置或檢索對象的列數。

css代碼：

body{font:14px/1.5 georgia,serif,sans-serif;}
p{margin:0;padding:5px 10px;background:#eee;}
h1{margin:10px 0;font-size:16px;}
.test{
    width:628px;
    border:10px solid #000;
    -moz-columns:200px 3;
    -webkit-columns:200px 3;
    columns:200px 3;
}
.test2{
    border:10px solid #000;
    -moz-columns:200px;
    -webkit-columns:200px;
    columns:200px;
}

html代碼：

<h1>列數及列寬固定:</h1>
<div class="test">
    <p>This module describes multi-column layout in CSS. By using functionality described in this document, style sheets can declare that the content of an element is to be laid out in multiple columns. </p>
    <p>On the Web, tables have also been used to describe multi-column layouts. The main benefit of using CSS-based columns is flexibility; content can flow from one column to another, and the number of columns can vary depending on the size of the viewport. Removing presentation table markup from documents allows them to more easily be presented on various output devices including speech synthesizers and small mobile devices.</p>
</div>
<h1>列寬固定，根據容器寬度液態分佈列數:</h1>

結果如圖所示：

如下列出column運用的相關屬性
1.column-width：<length> | auto 設置或檢索對象每列的寬度
如：-moz-column-width:200px;

2.column-count：<integer> | auto 設置或檢索對象的列數
如：-webkit-column-count:3;

3.column-gap：<length> | normal 設置或檢索對象的列與列之間的間隙
如：column-gap:normal;column-gap:40px;

4.column-rule：[ column-rule-width ] || [ column-rule-style ] || [ column-rule-color ]設置或檢索對象的列與列之間的邊框。複合屬性。至關於border屬性

如：column-span:all;

6.column-fill：auto | balance 設置或檢索對象全部列的高度是否統一。

7.column-break-before：auto | always | avoid | left | right | page | column | avoid-page | avoid-column 設置或檢索對象以前是否斷行。

auto：既不強迫也不由止在元素以前斷行併產生新列
always：老是在元素以前斷行併產生新列
avoid：避免在元素以前斷行併產生新列

8.column-break-after：auto | always | avoid | left | right | page | column | avoid-page | avoid-column 設置或檢索對象以後是否斷行。

auto：既不強迫也不由止在元素以後斷行併產生新列

avoid：避免在元素以後斷行併產生新列

9.column-break-inside：auto | avoid | avoid-page | avoid-column 設置或檢索對象內部是否斷行。
