WeChat, also known as Weixin in China, is one of the most popular social media platforms in the world. Its built-in browser allows users to share web pages and content with friends and family. However, when it comes to sharing HTML-based content, such as a webpage with images, there can be issues with displaying these images correctly.
The Problem

2. Image sizes: WeChat's browser has limitations on the size of images that can be displayed. Large images may be resized or not displayed at all.
3. CSS styles: WeChat's browser may not support certain CSS styles or properties, which can affect the display of images and other content.
