Rem equal-to-scale horizontal and vertical screen adaptation solution

In responsive web design, rem units are often used to achieve equal-scale scaling, but when switching horizontally and vertically, the page display effect is often different. This article provides an effective solution to help you maintain a consistent user experience in different screen orientations.

Question: How to avoid horizontal and vertical display differences when using rem for equal-scale scaling?

Solution: Use media queries to control the maximum width of HTML elements and realize centered display.

Sample code:

 @media screen and (min-width: 640px) {
  html {
    max-width: 640px !important;
    margin: 0 auto !important;
  }
}

Code Explanation: When the screen width is greater than or equal to 640 pixels, the code limits the maximum width of the HTML element to 640 pixels and uses margin: 0 auto to center it horizontally. In this way, no matter whether the user is horizontal or vertical, the page content will be kept in a 640 pixel wide container, effectively solving the display difference caused by rem-element ratio zooming, and ensuring the visual consistency of the page under different devices and screen sizes. You can adjust the value of 640px according to actual needs.
