How to remove duplicate properties in css?

Question

css

I found out for myself that there are a lot of duplicates in css; in the position example, sometimes their values ​​are different.. I associate
this with git
.case_wrap .same__text {
margin: 90px 0 100px;
position: relative;
padding-left: 15px;
padding-right: 15px;
position: relative;
}
Is there a way to clean it automatically?? or manually??

It removes duplicates, but whether it removes such ones is a question, so I won’t give a 100% guarantee, try it, tell me.
