[英]“0” vs “none” as css attribute value
I usually put 0
as value when i want to remove something in css. 当我想在css中删除某些东西时,我通常将
0
作为值。 For example: 例如:
border: 0;
background: 0;
Is there any difference between 0
and none
? 0
和none
任何区别吗?
When used with composite styles like border
and background
, the values will correspond to different properties. 与
border
和background
等复合样式一起使用时,值将对应于不同的属性。
border: 0
will set border-width: 0
while border: none
will set border-style: none
. border: 0
将设置border-width: 0
而border: none
将设置border-style: none
。
background: 0
will set background-position: 0
while background: none
will set background-image: none
. background: 0
将设置background-position: 0
而background: none
将设置background-image: none
。
So, there is a difference. 所以,有一个区别。 In the case of the border, the difference doesn't make any visual difference as both remove the border, but for the background it can make a difference if you also set any other background properties.
在边框的情况下,差异不会产生任何视觉差异,因为两者都删除边框,但对于背景,如果您还设置了任何其他背景属性,它可能会有所不同。
