Avoid incorporating blank rulesets into your work

Having trouble accessing an HTML image from a CSS script. Can anyone help?

HTML

<!DOCTYPE html>
<html>
    <head>
        <title>MB</title>
        <meta charset="utf-8">
        <link rel="stylesheet" href="style.css">


    </head>
    <body>
        <div class="Top">
            <img class="img-Sale" src="Images/Sale.png" alt="Sale">

        </div>
    </body>
</html>

Answer №1

Imagine a ruleset as a set of guidelines for styling elements on a webpage. An empty ruleset means these guidelines are completely empty. Essentially, the warning is telling you not to do this:

.box-Empty {

}

If you try to add any CSS properties inside the curly brackets, like {background-color: red;}, they will have no effect.
