Positioning doesn’t work, the browser will move when you zoom in or out
Reply to the discussion (solution)
http://www.w3school.com.cn/css/css_positioning_absolute.asp Understand the concept of absolute relative, I don’t know what position you are talking about What is it? I don’t use it.
Try this:
When editing to the middle position, the display will be just right. When browsing, just zoom in or out and the browser will go to the left
<style>body{ position:relative;}h2.pos_abs {position:absolute;left: 400px;top: 77px; } </style>
You If you want to zoom in and out the left and right widths, you should use percentages instead of pixel units. The absolute positioning should be set at the outermost layer. The relative distance to the left is the right percentage
It should be like this. I recommend you a website. Learn css

If you want to zoom in or out the left and right widths, you should use percentages instead of pixel units, and absolute positioning should be set at the outermost layer. Which percentage is correct relative to who is left? Thank you for understanding
