2. QQ 아이콘을 글꼴로 만들고 글꼴을 참조합니다. 예를 들어 QQ 아이콘은 문자 A에 해당하며 다음과 같이 사용할 수 있습니다. 계열: my-font color:red ">A

3. svg-filter 필터를 사용하여 QQ 사진을 색칠해보세요. 아래는 svg 필터입니다.

이 SVG를 로컬 폴더에 저장하고 이름을 filter-test.svg로 지정하세요. 아이콘 색상을 변경하려면 CSS에 filter:url(filter-test. svg#a)- -----참고: 내 svg에는 ID가 a인 필터가 하나만 있습니다.

요약하면 첫 번째 방법은 디자이너에게 피곤하고 아이콘 이미지가 매우 크고 CSS 제어가 번거롭습니다. 아틀라스인 경우 변위를 계산해야 하며 두 번째 방법은 간단하지만 효과가 제한됩니다. 세 번째 방법은 매우 좋습니다. 아이콘에 스타일을 추가하려면 SVG 필터 세트를 만든 다음 필터를 통해 적용하면 됩니다. 브라우저는 SVG와 필터를 지원합니다.

그렇습니다. 개인적으로는 마지막 방법이 재사용과 공유를 위해 온라인에 걸 수 있는 필터이기 때문에 점차 이전 방법을 대체할 것이라고 생각합니다.
