Practical usage of CSS Filter
CSS filter Instantly change the visual presentation of an image or any HTML element without modifying the original file. Brightness and contrast are suitable for dealing with cover readability, grayscale and sepia can establish a consistent brand mood, hue-rotate can quickly explore color matching, and drop-shadow can generate shadows based on the outline of transparent content.
Multiple filters are calculated from left to right, so the order may affect the results. In order to maintain text and image legibility, check again on the actual background after reducing opacity or contrast. Applying a large number of blur may also increase the browser's drawing cost, especially when animation, it needs to be restrained.

- Drag each parameter and toggle side-by-side or slider comparisons.
- After confirming the result, copy the CSS and paste it into the style of the target element.
