CSS not changing the text color-CodePudding

Using Bootstrap4, have set up a div with the class of greenfooter (that takes care ofthe background color and padding), inside I created a container with four columns.

I set up the css to turn the H5 a lighter green color, and set the a tag to be white and lighter green/no text decoration when hovered.

The css code for the color change isn't working, and I think my css is incorrect, can anybody see where I went wrong?

css

    .greenfooter {
        background-color: #5C8627;
        color: white;
    }
    .greenfooter.container.row.col-md-3 h5 {
        color: #C8E72F;
    }

    .greenfooter.container.row.col-md-3 a {
        color: #ffffff;
    }

    .greenfooter.container.row.col-md-3 a:hover {
        color: #C8E72F;
        text-decoration: none;
    }

CodePudding user response：

container is child of greenfooter class element so, a space is needed and so on for row, col-md-3 and h5

.greenfooter {
    background-color: #5C8627;
    color: white;
}
.greenfooter .container.row.col-md-3 h5 {
    color: #C8E72F;
}

.greenfooter .container .row .col-md-3 a {
    color: #ffffff;
}

.greenfooter .container .row .col-md-3 a:hover {
    color: #C8E72F;
    text-decoration: none;
}
