CSS边距用于在任何元素之间留出空间为此我们在CSS中使用“ margin”属性 。 Syntax: 句法 Element{
margin: length|auto|initial|inherit;
}
保证金崩溃 (Margin Collapsing) When two margins are touching each other vertically, they are collapsed. But when they touch horizontally, they do not collapse. 当两个边距垂直相互接触时它们将被折叠。 但是当它们水平接触时它们不会塌陷。 Example: 例 !DOCTYPE html
head
style
div {
margin: 20px;
}
/style
/head
html
body
div
Some content
/div
div
Some more content
/div
/body
/html
Output 输出量 They will be 20px apart since vertical margins collapse over one and other. (The spacing will not be the sum of two margins.) 由于垂直边距会彼此重叠因此相距20px 。 (间距将不是两个边距的总和。) 在给定边上应用保证金 (Apply Margin on a Given Side) In CSS you can specify a given side to apply a margin too. The four properties provided for this purpose are, 在CSS中您也可以指定给定边以应用边距。 为此目的提供的四个属性是 margin-left 左边距 margin-right 右边距 margin-top 上边距 margin-bottom 底边 Example: 例 !DOCTYPE html
head
style
#myDiv {
margin-left: 30px;
height: 100px;
width: 100px;
background-color: red;
}
/style
/head
html
body
div idmyDiv
Some content
/div
/body
/html
Output 输出量 负边距 (Negative Margins) CSS has properties that can be set to negative values. This property can be used to overlap elements without absolute positioning. CSS具有可以设置为负值的属性。 此属性可用于重叠元素而无需绝对定位。 Example: 例 !DOCTYPE html
head
style
.over {
margin-left: -20px;
background-color: #f40;
color: #fff;
}
/style
/head
html
body
div classover
Some content
/div
/body
/html
Output 输出量 保证金属性简化 (Margin property simplification) Here the shorthand is used to specify margin in every direction without writing for every direction. 在这里速记用于指定每个方向上的边距而无需为每个方向编写。 Example: 例 !DOCTYPE html
head
style
p {
margin: 1px;
/* 1px margin in all directions */
background-color: #f40;
color: #fff;
}
/style
/head
html
body
p
Some content
/p
/body
/html
Output 输出量 边距CSSlength | auto | initial | inherit (CSS for margin: length|auto|initial|inherit) margin: 1px;
margin: 1px 1px;
margin: 1px 1px 1px;
margin: 1px 1px 1px 1px;
左右上和下边距 (Left, Right, Top and Bottom Margins) To provide margins for left, right, top and bottom to an object, we can use margin-left, margin-right, margin-top and margin-bottom properties respectively. 要为对象的左侧右侧顶部和底部提供边距我们可以分别使用margin-left margin-right margin-top和margin-bottom属性。 Example: 例 !DOCTYPE html
head
style
p {
margin-left: 10px;
margin-right: 10px;
margin-top: 20px;
margin-bottom: 30px;
/* 1px margin in all directions */
background-color: #f40;
