How can class selectors enhance CSS styling?

Class selectors are a powerful feature in CSS that allow you to apply styles to multiple elements simultaneously. When you define a class selector in your stylesheet, you can assign that class to any number of HTML elements within your webpage. This means that instead of needing to write separate CSS rules for each individual element you want to style, you can simply use the class selector to apply the same styles across many elements.

For example, if you have multiple <div> tags that require the same background color and font properties, you can create a class called .highlight and apply it to all those <div> tags. This not only streamlines your CSS code but also promotes consistency throughout your design, as any changes made to the styles for that class will automatically reflect across all associated elements.

In contrast, other options focus on aspects such as targeting a single HTML element (which doesn't leverage the full power of classes), overriding existing styles (which can be a function of specificity rather than class selectors), or excluding elements from being styled (which is not an inherent capability of class selectors). Thus, the ability to apply and reuse styles efficiently across multiple elements is what makes class selectors particularly valuable in CSS styling.
