To set the div to be centered in css, we can achieve it through the following methods.
Positioning method: position:absolute
If the child div has a defined width and height, you can use this method. Note: The values of margin-top and margin-left are half of the height and width values. You can try it and see the effect.
margin:auto method
This can also be a positioning method. Using this method requires that the child div must be set to a width value, otherwise it will have no effect~margin:auto is centered horizontally and vertically. If you only set the horizontal centering, you can set it to margin:auto 0; similarly, if you only set the vertical centering, Can be set to margin:0 auto
display:table-cell method
This method is mainly used for vertical center alignment of multi-line text content. Note: text-align:center sets the horizontal center alignment of the text, and vertical-align:middle sets the vertical center alignment.
transform:translate(x,y) method
This is a new attribute in css3. It can be used if the child element does not set the width and height values. Use this method to achieve it. This can be used when we make adaptive pages.
before, after pseudo-element method
