How to delete the default style of the uniapp project carousel and change it to a custom style

In the project, in order to give users a better visual experience, sometimes we need to change the style of the carousel swiper component provided on the uniapp official website to a custom style.

1. Remove the indicator-dots attribute ( whether to display panel indicator dots ) in the component.

2. You need to write a big box to wrap the swiper and view (where the indicator points are placed). Positioning: The father is in harmony with the son, so that the indicator point is centered

3. Give the carousel image a change event (change). When the image changes, the color of the indicator point changes.
