button{
    background: black;
    border: none;
    padding: 10px 20px;
    display: inline-block;
    font-size: 1rem;
    font-weight: 800;
    width: 200;
    cursor: pointer;
    transform: skew(-21deg);
    span{
        display: inline-block;
    transform: skew(21deg);

    }

        }
    }

CodePudding user response:

Assuming that you're using standard stylesheet, you can't use nesting in styles. For example:

button {
   span {
       ...
   }
   ::hover {
       ...
   }
}

Css shown in snippet above is not valid(or standard) css. You can either do something like this:

button {
   ...
}
button span {
    ...
}
button::hover {
    ...
}

or you can use scss, which is a css preprocessor and allows you to use nesting and other cool features. For details or more ways to implement css in React, read this.
