CSS horizontally centered and vertically centered multiple solutions

CSS tutorials A variety of solutions that are centered horizontally and vertically
Vertical-align is a good attribute, but this attribute was initially for the cell of the table. Of course, this property does not work on block-level elements, but it works on inline elements such as spans (this time, the property is set to a negative element content to move down, positive values move up).

The following is a more professional, vertically centered, centralized solution. Recorded here for inspection.

1, single line vertically centered

The text is vertically centered in the layer Vertical-align property is not available. We have a more ingenious way here: the height of the set height is the same height as the line-height!

Example source code [www.jzread.com]
<div style= "line-height:500px;height:500;" >
2, the level of the center

Set div width Less than the width of the parent div, set margin:0 auto;

Example source code [www.jzread.com]
#parentdiv
{
width:500px;
}
#childdiv {
width:200px;
margin:0 Auto;
}
3, the level of text horizontally centered

In Childdiv CSS plus text-align:center;

Example source code [www.jzread.com]
#parentdiv
{
width:500px;
}
#childdiv {
width:200px;
margin:0 Auto;
Text-align:center;
}
4, the DIV layer vertically centered

 example source code [www.jzread.com]
<div style= "Width:275px;height:375px;border:solid red;"
<div style= "background:green;height:375px; width:275px; position:relative; Display:table-cell; Vertical-align:middle; "
     <div
           style= Background:red;position:static;position:absolute9; top:50%; "
