MIUI 옵션 상자 스위치 스타일 시뮬레이션-HTML 튜토리얼-php.cn

IOS용 스위치 시뮬레이션도 있고, 물론 MIUI용 스위치 시뮬레이션도 있습니다

설정 옵션에서 스위치 스타일을 보다가 갑자기 해보고 싶어졌습니다

최종 효과는 아래와 같습니다.

구현 과정

1. 옵션 상자 체크박스

물론 아날로그 스위치에는 옵션박스가 필요하며 여기서는 체크박스 체크박스를 사용합니다

2. 전환 과정을 이해하세요

스위치 버튼을 클릭하여 켜거나 끌 수 있습니다. 기본 체크박스는 아이콘의 효과를 얻을 수 없으므로 그림에서 스위치를 표현하려면 추가 요소가 필요합니다

그리고 체크박스의 클릭 효과와 클릭 후 체크 여부의 효과를 활용해야 체크박스를 숨길 수는 없지만 덮어쓸 수는 있습니다

중복 태그 사용을 줄이기 위해 의사 요소(before 및 :after)를 사용할 수 있으며 태그 구조는

3. 스위치 구현

:before 의사 요소를 스위치 배경 레이어로 사용하고 :after 의사 요소를 스위치 항목(예: 작은 원)으로 사용합니다.
