Allowing users to upload images that are displayed in a square container in the UI presents challenges. The uploaded images can vary in size, aspect ratio, and orientation, but they should always fill the container and be centered.
To address this issue, I aim to style the images so that the smaller dimension is set to a specified size while maintaining the original aspect ratio.
If I want all images to have a resulting dimension of 50px (for the smaller side), the conversions would be as follows:
- Portrait image: 100px(w) x 200px(h) => result: 50x100
- Landscape image: 200px(w) x 100px(h) => result: 100x50
- Square image: 100px(w) x 100px(h) => result: 50x50
I require the images to be at least 50px in either dimension. By using max-width and max-height properties, the images will resize to at most 50px...
Criteria for the original approach
- CSS only should be used
- The images must be IMG tags and should not be placed as backgrounds
- Avoid using Javascript
While experimenting with max-dimension styles, I found that controlling both dimensions simultaneously was challenging. I am seeking a solution that addresses this limitation.
Considerations for an alternative approach
The requirements of the original solution may prove too restrictive. In such cases, utilizing CSS backgrounds as outlined in this question could be considered. However, my challenge lies in dynamically defining the images at runtime when users select them, requiring inline styles which I prefer to avoid.
