重用CSS样式并应用于其他HTML元素

Question

I would like to reuse given css formatting .parsley-errors-list > li and apply it to different HTML element than it it designed to be used for. I would like to apply it to <span> in order not to create another duplicated style and to be sure that span will always be of the same style as .parsley-errors-list > li .

.parsley-errors-list {
    display: none;
    margin: 0;
    padding: 0;
}

.parsley-errors-list > li {
    font-size: 12px;
    list-style: none;
    color: #f05050;
}

EDIT:

Given CSS sample is part of an updatable theme, so I would like to avoid changing it for the maintainability.

Answer 1

That's very easy to do. Just put a comma on the CSS selector like this:

.parsley-errors-list > li, span {
    font-size: 12px;
    list-style: none;
    color: #f05050;
}
