Mobile carousel image height adaptation: Can CSS achieve image height adaptation?

In mobile web design, carousel map height adaptation is a common challenge. How to make carousel pictures perfectly displayed under various screen sizes without affecting the page layout is the focus of many developers. Especially when avoiding JavaScript, can CSS alone achieve high image adaptability? This article will discuss this.

The core question is: How to ensure that the carousel image can be displayed optimally under different screen sizes? It is an easy way to directly set the carousel image width to 100% so that the image width is adaptable and the height is fixed to the preset value. But this depends on the UI design draft and may cause the picture to be deformed or displayed incompletely.

Another common method is to fix the carousel graph height and adapt to width. This also depends on the exact picture size provided by the UI design draft, and the front-end developers can set a fixed height according to the design draft. This method ensures the image proportions and avoids deformation, but lacks flexibility, and different sizes of pictures may require maintenance of multiple styles. In fact, this is not really a picture height adaptation, but a preset height.

Therefore, using CSS alone, it is difficult to achieve true image height full adaptability, usually requiring preset height or width and adjust according to the design draft. To achieve more flexible adaptation, it is usually necessary to dynamically obtain image height in combination with JavaScript.
