How to center the photo vertically with css
Use absolute positioning to achieve vertical centering
1. Add to the parent element of img Relative positioning attribute (position: relative), and at the same time, add an absolute positioning attribute (position: absolute) to the child element, that is, the image 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. This value is half the height of the element you want to vertically center. *If you are not sure about the height of the element, you can not use margin. -top, instead use the transform:translateY(-50%); attribute.
Remember: If you want to center horizontally at the same time, you can do it using the same technique you use to center vertically.

<html>
<head>
<style type="text/css">
.posdiv{
width: 300px;
height: 250px;
position: relative;
border:1px solid red;
