Why background-clip: content-box doesn't work?-CodePudding

In the given code background-clip: padding-box; is working but the background-clip: content-box; isn't working. Please tell me what is wrong here. I found that padding must be there for the background-clip property to work and I have added the padding as well.

CodePudding user response：

Your code is working, you just added the padding to the wrong element ".temp h3" instead of ".temp"
