Is the centering of the Bootstrap image responsive?
Article Introduction：The responsiveness of the centered Bootstrap image depends on the specific situation. text-center is only valid for in-line elements, while mx-auto needs to rely on the width of the parent element, which may cause the image to be centered and distorted. The best way to achieve responsive image centering is to use container elements to set width and mx-auto for horizontal centering, or use the Bootstrap grid system to finely control the layout. A common mistake is to use text-center or mx-auto directly on the image. For performance optimization, appropriate image sizes should be used and best practices should be followed. Understanding principles rather than blindly using classes will help avoid traps and write efficient code.
