Tips for making clip-path: path(...) to crop graph adaptive size

When cropping a graph with clip-path: path(...) , it is a common problem to make it automatically resize based on the button size. This article will provide a solution.

The key is to use relative units (percentages). In this way, no matter how the button size changes, the clipping path will be adjusted accordingly.

First, understand the coordinate system of path function. Assuming the button width is width and the height is height , the path point is defined using percentages. For example, crop a circle:

 clip-path: path('M 50% 0 A 50% 50% 0 0 1 100% 50% A 50% 50% 0 0 1 50% 100% A 50% 50% 0 0 1 0 50% A 50% 50% 0 0 1 50% 0 Z');

M 50% 0 means starting from the top of the center of the button; A 50% 50% 0 0 1 100% 50% Draw an arc with a radius of half the width and height of the button, and so on.

By percentage, the path is scaled proportionally regardless of the button size changes, for an adaptive effect.

To crop other shapes, just adjust the path coordinates according to the shape and use percentages to make sure they fit different sizes.
