How does css center the photo vertically?

Using absolute positioning to realize vertical centering

1. Add a relative positioning attribute (position: relative) to the parent element of the img, and an absolute positioning attribute (position: absolute) to the child element, that is, the picture img element.

2. Set the top attribute of the picture element to 50%.

3. Now we need to set a negative margin-top value for the img element, which is half the height of the element you want to center vertically. * if you are not sure the height of the element, you can use the transform:translateY (- 50%) attribute instead of margin-top.

Remember: if you want to center horizontally at the same time, you can do it with the same technique as vertical centering.

Examples are as follows:

.posdiv {width: 300px; height: 250px; position: relative; border:1px solid red;}. Posdiv img {width: 100px; position: absolute; top: 50%; margin-top:-50px;}
