This article introduces the relevant knowledge of "how to align an absolute positioning div horizontally and vertically". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!
In general, you can add a margin:0px auto to an element to center the element horizontally on its parent element, and then set it to be vertically centered. But adding margin:0px auto to absolutely positioned objects doesn't work, so do it the old-fashioned way.
The code example is as follows:
The code is as follows:
Ant tribe
.father
{
Width:600px
Height:600px
Background-color:green
Margin:0px auto
Position:relative
}
.children
{
Position:absolute
Width:200px
Height:200px
Left:200px
Top:200px
Background-color:red
}
The above code can center the child div horizontally and vertically in the parent div. Here are a few key points:
1. The parent element uses relative positioning so that the child element can use it as a displacement reference object.
The 2.top attribute value is calculated by the height of the parent element / 2-child element / 2 lens left attribute value: the parent element width value / 2-child element width value / 2.
